Abstract: Image segmentation is an important initial operation before building databases for GIS use. Otsu method is a fast and efficient thresholding approach because it is minimizing within class variance. In this study image segmentation has been done by using Otsu thresholding. First, an image contains two main cover types processed by Low Pass filter to enhance separation between classes.Then, use thresholding to segment image into distinct regions (classes), water and land cover. Finally, each distinct region will store in binary image to uses in later image processing. Keywords: Segmenting of remote sensing, thresholding approach, binary image.

Abstract: To investigate the health of vegetation and soil purity in some areas south- western Mosul city, multi spectral remote sensing and Analytical Spectral Device (ASD) field spectrometer were used. Landsat ETM+ image was used to identify tonal spectral anomaly after correct it spectrally by using ENVI’s FLAASH method. A combination of False color composite image (FCC) based on the spectral characteristics of vegetation and soils was selected. This combination consists of (Band7-Red, Band4-Green, Band1-Blue) and also used to express the subtle grey tones as color variations and then some of anomalous reflectivity zones were extracted. Field spectral measurements were applied to determine the spectral reflectance anomaly of vegetation and soils. The spectral measurements of the samples were made in spectral analysis laboratory at (Remote Sensing Center- Mosul University) on a number of samples with a full-range of ASD spectrometer (i. e. 350m to 2500m), both on and off the anomalous spectral zones in order to compare the spectral changes between them. The results confirmed to the existing these reflectance zones by determination an increase in the reflectance at the chlorophyll absorption as well as a shift in the position of the red edge. The results also have indicated that the anomalous relationship between the occurrence of hydrocarbon seepages and anomaly reflectance zones. In this context, the migration of hydrocarbons has a predominantly structural control, related to the listric fault and accompanying fractures..

Abstract: Pegmatite intrusions represent one of the distinguished geological features which are exposed in the north western part of Zagros Suture Zone-ZSZ whose forms appear like dikes and its contain of Volcano-Sedimentary units. In order to determine these features in some areas northern Iraq, remote sensing techniques were used by applying selective image processing methods for determining the spectral signature of these intrusions. Lithological samples were collected and analyzed geochemically and specify Mode analysis of minerals phases and consequently determination the suitable samples for spectral extraction. Depending on the extracted spectral, digital classification was applied on the corrected satellite images to extract the compatible spectral signatures between pegmatite intrusions (in satellite images) and pegmatite field samples. The results showed coincident between this two pegmatite and also determine another zones of pegmatite out of studied area. The density of pegmatite is more in the zone which is located northwestern part from samples area and low density in the other area. The research method gave good efficiency in pegmatite investigation by clarifying these features on the satellite images.ً.

Abstract: A structural and tectonic study was carried out in the area between Baikher and Shaikhan anticlines. It is revealed that the main distinct structural feature is an anticline extending 16 Km northwest – southeasterly obeying the Zagros Range trend. This anticline with 6 km width and 16 km length called Brifka Anticline. Several geologic formations are exposed in the studied area, ranging in time span from the Paleocene to Miocene periods. These formations are Kolosh, Khurmala, Gercus, Avanah and Pila Spi where Kolosh represented the core and Pila Spi makes the carapace of the anticline. The geometrical analysis of this fold along four selected traverses revealed that the anticline is asymmetrical, mostly overturned and verged towards southwest, except in the fourth traverse it is appeared verging towards south. The anticline axis is oriented northwest -southeasterly in the first three traverses whereas it trended towards east- west in the fourth one. The study included the vertical investigation of fold style of folded formations. It appeared that the anticline axis in Pila Spi Fn. is slightly changed from that of Kolosh Fn. in the first and forth traverses, whereas it changed anti clockwise 11-16° from Kolosh to Pila Spi formations in the second and third traverses. The present study showed that the systems okl>c and hol>c are the most dominant joints in the first three traverses whereas hko>a system and ac set are abundant in the fourth traverse. It also revealed that the system hko>a are more abundance than hko>b system which indicate that the compression phase was tensive than the alternative tension. Faults were investigated by field work and satellite image interpretation. It revealed three strike-slip faults inclined to the fold axis. They are BF1, BF2 and Besary faults. Another fault was concluded from the geometric properties and vergency of Brifka anticline. It is a foreland listric fault. This was followed by the determination of the formation thicknesses in order to conclude the sense of displacement of this fault. The determination appeared that the thicker sediments are in the area of the southwestern limb reflecting that the fault is reactivated as reverse foreland listric fault.(.

Abstract: The present study included identification and systematic description of some ammonites from the upper part of Chia Gara Formation, on the southern limb of Maten anticline at Amadia area, northern Iraq. Six species belong to five genera and three families were described. The two species; Berriasella privasensis and Parodontoceras calistoides were previously identified, and four species were left under open nomenclature, due to bad preservation and lack of material, these are; Parodontoceras sp., Spiticeras (Kilianiceras) sp., Substeueroceras sp. and Haploceras sp. The studied ammonites occur as an assemblage fauna in the Durangites Zone, which indicates Late Tithonian age for the upper part of Chia Gara Formation in the Amadia area..

Abstract: Rock magnetic properties have been investigated across the Paleocene/Eocene boundary in two distally separate sections of Paleogene marine sedimentary rocks from Iraq, namely the Sinjar and the Shaqlawa sections. The sediments at the studied sections belong to the Aaliji and the Kolosh formations respectively, which were previously examined for their biostratigraphy by the authors using planktonic and benthonic foraminifera to delineate the Paleocene/Eocene (P/E) transition. Measured magnetic properties include; bulk magnetic susceptibility, hysteresis cycles, isothermal remnant magnetization (IRM) acquisition, and thermomagnetic curves analysis. Rock-magnetic results (i.e. low magnetic coercivity component) indicate greigite as the main magnetic phase at Aaliji rocks, while a mixture of magnetite and greigite with high magnetic coercivity has been observed at Kolosh clastics. Magnetic susceptibility is induced by related to both biogenic minerals (mainly at Aaliji Formation) and transported terrigenous material sources. Multi varied magnitude phases of high bulk rock magnetic susceptibility observed in both formations along PETM lithosomes are attributed to two sources: greigite or biogenic iron oxides source and increase in terrigenous discharge source as inferred by anoxic to suboxic iron - sulfate-reducing conditions and lithological change respectively. Both sources referred to some of environmental conditions associated with Paleocene - Eocene thermal maximum events such as methane dissociation, water stratification, enhanced hydrological and weathering cycles..

Abstract: Rock slopes analysis in south western limb of Perat anticline, near Bekhme village, were studied. Seven stations were chosen to study these slopes which distributed along several exposed formations of Bekhme, Shiranish, Tanjero, Kolosh, Khurmala, and Gercus interbeded with Pila Spi according to their existence on the road, beginning from the Iron Bridge of Bekhme. Stereographic projection technique was used in analyzing and classifying these slopes. Plane sliding along bedding planes and joints is the predominant in the formations of Bekhme, Shiranish, Pila Spi and some of khurmala Formation. Clastic rock Formations of Tanjero, Kolosh, and Gercus help to failure in steep and moderate slopes. Because of no distinctive favorable discontinuities to slide along, these slopes are suffering from raveling processes which means granular disintegration into small components by different processes. The rock slopes of Khurmala Formation are affected by wedge sliding along discontinuities intersections with bedding planes.

The first layer represents the topsoil layer having velocity ranges between (350 m/sec-700 m/sec), and thickness up to 3.2m. The second layer having velocity ranges between 840-1700m and thickness between (3m-14.7m), mostly representing the river deposits, composed specially of river terraces and clays. The third layer was having velocity ranges between (1900 m/sec-2800 m/sec) and depth ranges between (3.0m-17.9m) representing the hard bed, which is mostly composed of marl layers belong to the upper part of Fat’ha Formation.تضمنت الد ا رسة إج ا رء مسح زل ا زلی انکساری تصویری لمشروع المستشفى التعمیمی فی جامعة الموصؿ عمى امتداد 12 مسا ا رً بمساحة إجمالیة مقدارىا 35140 متر مربع. الیدؼ مف المسح الزل ا زلی ىو الکشؼ عف نوعیة وسمؾ الطبقات الصخریة وامتدادىا. ت المسح بوساطة جیاز ) ABEM Terraloc Mk6 ) السویدی الصنع وتمت معالجة البیانات الحقمیة وتمثیمیا باستخدا مجموعة برنامج SeisImager™ /2D لعمؿ مقاطع تصویریة (Tomography) لمطبقات تحت السطحیة. بینت نتائج المسح الزل ا زلی الانکساری وجود ثلاث طبقات فی منطقة الد ا رسة . الطبقة الأولى تمثؿ طبقة مف الترب السطحیة والتی تمتمؾ سرعة زل ا زلیة تت ا روح بیف) 350 /ثا 700 /ثا ( وسمؾ یصؿ إلى ) 3.2 ( - ، والطبقة الثانیة تمتمؾ سرعة زل ا زلیة - تت ا روح بیف ) 840 1700 /ثا( وسمؾ یت ا روح بیف ) 3 - 3 14.7 ( وىی عمى الأغمب تمثؿ طبقة مف الترسبات النیریة (River deposits) والمتکونة بصورة خاصة مف المدممکات النیریة (River terraces) والمواد الطینیة. أما الطبقة الثالثة فتمتمؾ سرعة زل ا زلیة تت ا روح بیف) 1900 /ثا 2800 /ثا ( وعمؽ یت ا روح - بیف ) 17.9 3.0 (، وىی الطبقة الصمبة والتی ىی عمى الأغمب طبقة مف صخور المارؿ العائدة إلى - الجزء العموی مف تکویف الفتحة.

Abstract: The present work includes structural analysis and synthesis of Bashiqa and AL-Fadhlya Anticlines, located (25) km northeast Mosul City – northern Iraq. These structures extend in NW – SE trend for about 25 km within the Foreland Fold Belt of Iraq. Geometrical classification of these folds based on stereographic analysis refers that they were developed by horizontal compressive stress in NE – SW direction. Furthermore, Fourier analysis revealed that SW limbs of both folds are relatively more developed than their NE limbs. This might be ought to higher stress intensity developed within SW limbs of both Anticlines. Such a higher stress intensity expressed in further flexure of SW limbs a round secondary hinges, multi reverse slip faults in SW limb of Bashiqa Anticline, local overturning and minor folding in SW limb of AL-Fadhlya Anticline. The study also revealed a marked variance in detachment depth and shortening percentage between these structures. Bashiqa is deeply detached and less shortened than AL-Fadhlya. Detachment depth variance might be attributed to inversely reactivation of two en – echelon arranged, varied depth, Foreland verged detached faults beneath Bashiqa and AL-Fadhlya folds. Inverse reactivation of these detachment faults during compressive phase led to differential folding and hence detachments of the two folds across a dextral subsurface strike slip fault transverse to these folds. The later one may play as an accommodation fault for differential reverse movement on the varied depth detachment faults beneath these folds. However, wide hinge area of Bashiqa Anticline, disruption of its both limbs by many reverse slip fault have contributed in depletion a considerable amount of shortening compared with AL-Fadhlya Anticline shortening. التحمیل الترکیبی و التکتونی لطیتی بعشیقة والفاضمیة المحدبتین – شمالی الع ا رق 89 The structural model proposed here for Bashiqa and AL-Fadhlya Anticlines is such that: the transversal subsurface strike slip faults (SF3, SF4 of Mutab, 2000) are lateral ramps of Foreland verged detachment faults beneath these structures. The main reverse slip faults on both limbs of Bashiqa fold and that one disrupting (SW) limb of Maqlub Anticline, might linked at depth with the proposed main detachment fault deep seated under Bashiqa structure. Inverse reactivation of this as well as the other shallower under AL-Fadhlya Anticline together with resulting synthetic and antithetic reverse slip faults have effectively contributed in folding process and its style in this area.تتضمن الد ا رسة الحالیة طیتی بعشیقة والفاضمیة الواقعتان عمى بعد 25 کم شمال شرق مدینة الموصل ضمن نطاق طیات الفورلاند فی الع ا رق. تمتد ىاتین الطیتین لمسافة حوالی 25 کم بأتجاه شمال غرب جنوب – شرق. التحمیل الیندسی لمطیتین یشیر إلى أنیما قد تکونتا نتیجة اجیادات أفقیة قادمة من جیة الشمال الشرقی، وان التحمیل الریاضی لمطی )تحمیل فوریر( یظیر بأن الجناح الجنوبی الغربی فی کل من الطیتین ىو أکثر من الجناح الشمالی الشرقی، إذ ان شدة الإجیاد فی الجناح الجنوبی الغربی أدت إلى تکوین خط مفصل ˝ تطو ا ر ثان لمطیتین فی ىذا الجناح، وکذلک إلى تعدد الفوالق العکسیة فی الجناح الجنوبی الغربی لطیة بعشیقة، فضلا عن الانقلاب الموضعی لمطبقات وتکون طیات ثانویة فی بعض المواقع فی الجناح الجنوبی الغربی لطیة الفاضمیة. أ وظیرت الد ا رسة تباینا فی عمق سطح الانفصال ونسبة التقصیر بین طیتی بعشیقة )أکثر عمقا واقل تقصی ا ر( و الفاضمیة )اقل عمقا وأکثر تقصی ا ر(. أوعز اختلاف عمق سطح الانفصال إلى احتمال وجود فالقی انفصال فورلاندیی الاتکاء ومختمفی العمق ومفصولین تناسقیا بفالق مضربی. إن انعکاس الحرکة عمى ىذین الفالقین فی فترة الانضغاط ساىم فی طی الطیتین بشکل أدى إلى انفصالیما عبر فالق مضربی یمینی تحت سطحی مستعرض. وىو فالق توفیقی لمحرکة العکسیة عمى فالقی الانفصال المتباینین فی العمق تحت الطیتین. إن تفاوت الطیتین من حیث الحجم قد یکون سبباً فی تباین نسب التقصیر بین الطیتین )بعشیقة اکبر بکثیر من الفاضمیة(. یشییییر المودییییل الترکیبیییی المقتیییرح فیییی الد ا رسیییة الحالییییة إلیییى أن الفیییالقین المضیییربیی الإ ا زحیییة تحیییت السیطحیین ) SF3,SF4 ( ىمییا عبییارة عیین مصیطبتین جییانبیتین لفییالق الانفصییال الفورلانییدی الاتکیاء تحییت طیییة بعشییقة. و قید تیرتبط الفوالیق المعکوسیة الرئیسیة فیی جنیاحی طییة بعشییقة والفیالق المعکیوس الیرئیس فیی الجنیاح إب ا رىیم سعد إب ا رىیم ألجمیمی و أحمد غانم نایف الع ا زوی 88 الجنیوبی الغربیی لطییة مقمیوب فیی الأعمیاق میع فیالق الانفصیال الیرئیس. کمیا أسییم انعکیاس الحرکیة عمیى فیالق الانفصال الرئیس وما نتج عنیا من فوالق عکسیة متوافقة وغیر متوافقیة بشیکل فعیال فیی عممییة الطیی وطی ا رزه فیی طیتی بعشیقة والفاضمیة.

Abstract: The present research includes studying the electrical resistivity and some engineering parameters (plasticity index, California Bearing Ratio, dry density, clay content, moisture content) for the Soil subgrade of the roads. Six sites were selected to conduct the study at Nineveh Governorate in Northern Iraq. Three of them are located to the east of Tigris river while the others to the west of it. Each site contains four locations, each of them includes five traverses with five sounding points in each traverse. The Constant Separation Traversing and Vertical Sounding are employed for delimitating the resistivity parameters, horizontally and vertically, with Wenner deployment. The field data were represented with six isoresistivity sections which indicate lateral and vertical variations reflecting subgrade soil inhomogeneities in the study area. The required laboratory tests are carried out for the recognition of the physical characteristics for soil classification and determination of the engineering parameters. As well, the present study tried determining relationships between electrical resistivity and engineering parameters through the results of the statistical correlation analysis. The study recommended the possibility of using isoresitivity sections in selecting for the proper sites for subgrade soil samples, and subsequently ending the random method in collecting the samples which always used.تضمن البحث الحالی د ا رسة المقاومیة الکیربائیة وبعض المعاملات الیندسیة )دلیل المدونة ونسبة التحمل الکالیفورنی والکثافة الجافة ونسبة الطین ومحتوى الرطوبة( لمتربة المستخدمة کطبقة أساس لمطرق. تشمل منطقة الد ا رسة ستة مواقع مختمفة من محافظة نینوى فی شمال الع ا رق، ثلاثة منیا تقع إلى الشرق من نیر دجمة اولثلاثة الأخرى فی الجانب الغربی لمنیر. یتضمن کل موقع أربعة م واضع ویشمل کل موضع خمسة أو ستة مسا ا رت لمقیاس حیث یتألف کل مسار من خمسة نقاط جس کیربائی بخمسة فاصلات قطبیة فی کل نقطة جس. تم استخدام أسموبی التحری ثابت الفاصمة والجس العمودی وذلک لتحدید معاملات المقاومیة أفقیا وعمودیا بترتیب وینر. رسمت البیانات الحقمیة عمى ىیئة مقاطع تساوی المقاومیة فی ستة مواقع وبینت النتائج وجود تغای ا رت أفقیة وعمودیة متباینة فی المقاومیة الکیربائیة اولتی تعکس عدم التجانس لمکونات تربة طبقة الأساس فی منطقة الد ا رسة. أجریت الفحوصات المختبریة اللازمة عمى عینات التربة لمتعرف عمى الخصائص الفیزیائیة وتصنیف التربة و ایجاد المعاملات الیندسیة لیا. کما حاولت الد ا رسة الحالیة ایجاد علاقات بین المقاومیة الکیربائیة والمعاملات الیندسیة من خلال نتائج تحمیل الارتباط إحصائیا لقیمیا. توصی الد ا رسة بإمکانیة الاعتماد عمى مقاطع تساوی المقاومیة فی اختیار المواقع الصحیحة لأخذ عینات تربة طبقة الأساس لمطرق لإنیاء الطریقة العشوائیة فی جمع العینات والمعتمدة غالبا.

The study recommended the possibility of using isoresitivity sections in selecting for the proper sites for subgrade soil samples, and subsequently ending the random method in collecting the samples which always used.تضمن البحث الحالی د ا رسة المقاومیة الکیربائیة وبعض المعاملات الیندسیة )دلیل المدونة ونسبة التحمل الکالیفورنی والکثافة الجافة ونسبة الطین ومحتوى الرطوبة( لمتربة المستخدمة کطبقة أساس لمطرق. تشمل منطقة الد ا رسة ستة مواقع مختمفة من محافظة نینوى فی شمال الع ا رق، ثلاثة منیا تقع إلى الشرق من نیر دجمة اولثلاثة الأخرى فی الجانب الغربی لمنیر. یتضمن کل موقع أربعة م واضع ویشمل کل موضع خمسة أو ستة مسا ا رت لمقیاس حیث یتألف کل مسار من خمسة نقاط جس کیربائی بخمسة فاصلات قطبیة فی کل نقطة جس. تم استخدام أسموبی التحری ثابت الفاصمة والجس العمودی وذلک لتحدید معاملات المقاومیة أفقیا وعمودیا بترتیب وینر. رسمت البیانات الحقمیة عمى ىیئة مقاطع تساوی المقاومیة فی ستة مواقع وبینت النتائج وجود تغای ا رت أفقیة وعمودیة متباینة فی المقاومیة الکیربائیة اولتی تعکس عدم التجانس لمکونات تربة طبقة الأساس فی منطقة الد ا رسة. أجریت الفحوصات المختبریة اللازمة عمى عینات التربة لمتعرف عمى الخصائص الفیزیائیة وتصنیف التربة و ایجاد المعاملات الیندسیة لیا. کما حاولت الد ا رسة الحالیة ایجاد علاقات بین المقاومیة الکیربائیة والمعاملات الیندسیة من خلال نتائج تحمیل الارتباط إحصائیا لقیمیا. توصی الد ا رسة بإمکانیة الاعتماد عمى مقاطع تساوی المقاومیة فی اختیار المواقع الصحیحة لأخذ عینات تربة طبقة الأساس لمطرق لإنیاء الطریقة العشوائیة فی جمع العینات والمعتمدة غالبا.

Abstract: In order to study the effect of dolomitization on Mergi Formation sequences (Cenomanian – Early Turonian), Field and petrographical examinations were carried out on fourty six meters (46m) of the type section of this formation. It has been observed that the formation is highly affected by diagenesis processes, especially dolomitization. On the other hand, the effects of other processes such as. cementation, dissolution, micritization and compaction in its both types, physical and chemical were less than dolomitization. Dolomite crystals appeared as rhomb-shaped euhedral to subhedral. The main diagnosed fabrics were Aphanotopic, Contact-rhomb porpherotopic, fogged mosaic, Sutured mosaic, Saddle dolomite and Cloudy-centered clear-rimmed dolomite fabrics. It is concluded that formation of dolomite was by the mechanism of mixing zone model and subsurface dolomitization model.(.

Abstract: A variety of image processing techniques were applied by the use of ENVI 5 program, on Landsat 7 ETM+ for a part of Bekhair anticline which is called Gara Barran anticline. It is located in the north of Duhok city, northern Iraq. Image processing methods were carried on (1, 2, 3, 4, 5, 7) image bands included: numerous false color combinations (RGB composites of three bands) were applied, and the best (741 RGB) was chosen. It was used as a base image for the two types of classification and geological mapping. It was comparted with a published geological map for the same area to indicate the name of the exposed geological formations in Gara Barran anticline which was identified at the field. Several image ratios were applied, and the best (2/3, 3/1, 2/5, 4/3, 5/7, 7/3 7/5) were chosen. In addition, the principal component analysis (PCA) (for all bands of Landsat7 image) was applied, only three of the resulted six components (PC3,PC4,PC5) were better and more useful than the other to discriminate some of the geological formations at Gara Barran anticline. Visual interpretation was applied on resulted images to identify the geological formation outcrops in Gara Barran anticline and the vegetation covered areas were also detected. Then all results were used to identify the exact training areas which were used in the supervised classification. Digital geological map was produced by the use of resulted images which were overlaid in Arc GIS 10.1 program and the transparency of the upper image was increased to 50%. By this way, the effect of vegetation cover was defeated then a digital geological map was exactly detected the geological formations with its contactsاستخدم برنامج ENVI 5 لتطبیق المعالجات الرقمیة المختمفة عمى مرئیة لاندسات 7 ETM+ لتحدید الوحدات الصخریة فی طیة کا ا ربا ا رن والتی تعد جزءا من طیة بیخیر الکبیرة والواقعة شمال مدینة دىوک فی شمالی الع ا رق. تضمنت المعالجات ال م نفذة عمى حزم المرئیة (1, 2, 3, 4, 5, 7) مایأتی: عممیة الدمج الممون الکاذب بعدة تولیفات، واختیار أفضل تولیفة والمتمثمة ب 741 RGB) (. إذ تم اتخاذىا کأساس فی عممیتی التصنیف والترسیم الخ ا رئطی ومقارنتیا بخریطة جیولوجیة منشورة لذات المنطقة لمتعرف عمى أسماء التکاوین الجیولوجیة المنکشفة فی طیة کا ا ربا ا رن والتی تم تمیزىا الزیارة حقمی اً. تطبیق المرئیات التناسبیة بصیغ مختمفة وکانت أفضمیا (2/3, 3/1, 2/5, 4/3, 5/7, 7/3, 7/5) . وتحمیل المرکبات الأساسیة لجمیع حزم مرئیة لاندسات 2، لینتج عنیا ستة مرکبات أساسیة، کانت أکثرىا فائدةً فی تحدید امتدادات بعض التکاوین الجیولوجیة فی طیة کا ا ربا ا رن المرکبات الأساسیة (PC3, PC4, PC5) . تم تفسیر نتائج المعالجات الرقمیة المختمفة بصریاً لتحدید امتدادات التکاوین الجیولوجیة المنکشفة فی طیة کا ا ربا ا رن وتحدید مناطق انتشار الغطاء النباتی الذی یغطی أج ا زء من المکاشف الصخریة فی الطیة. استخدمت المرئیات الناتجة من المعالجة الرقمیة فی تحدید عینات مناطق التدریب لکل تکوین جیولوجی بدقة )استنادا الى المرئیات المستحصمة من المعالجات فی أعلاه( لاستخدامیا فی عممیة التصنیف الموجو. ولرسم وانتاج الخریطة الجیولوجیة الرقمیة، تم تطبیق العدید من عممیات المطابقة (Overlays) لممرئیات الناتجة من المعالجة الرقمیة مع تنظیم مستوى الشفافیة (Transparency) لممرئیة العمیا الى 11 % من خلال برنامج نظم المعمومات الجغ ا رفیة ArcGIS10.1 مما ساعد فی التغمب عمى تأثی ا رت الغطاء النباتی فی نبیل قادر الع ا زوی ریان غازی البناء مثنى محمد ثابت قسم عموم الأرض مرکز التحسس النائی قسم عموم الأرض کمیة العموم جامعة الموصل کمیة العموم جامعة الموصل جامعة الموصل نبیل قادر بکر الع ا زوی و آخرون 566 حجب الرؤیة فی بعض أج ا زء طیة کا ا ربا ا رن ورسم خریطة جیولوجیة رقمیة حددت بدقة إمتدادات التکاوین الجیولوجیة والحدود الفاصمة فیما بینیا.

Abstract: Rock magnetic properties have been investigated across the Paleocene/Eoceneboundary in two distally separate sections of Paleogene marine sedimentary rocksfrom Iraq, namely the Sinjar and the Shaqlawa sections. The sediments at thestudied sections belong to the Aaliji and the Kolosh formations respectively, whichwere previously examined for their biostratigraphy by the authors using planktonicand benthonic foraminifera to delineate the Paleocene/Eocene (P/E) transition.Measured magnetic properties include; bulk magnetic susceptibility, hysteresiscycles, isothermal remnant magnetization (IRM) acquisition, and thermomagneticcurves analysis. Rock-magnetic results (i.e. low magnetic coercivity component)indicate greigite as the main magnetic phase at Aaliji rocks, while a mixture ofmagnetite and greigite with high magnetic coercivity has been observed at Koloshclastics. Magnetic susceptibility is induced by related to both biogenic minerals(mainly at Aaliji Formation) and transported terrigenous material sources. Multivaried magnitude phases of high bulk rock magnetic susceptibility observed inboth formations along PETM lithosomes are attributed to two sources: greigite orbiogenic iron oxides source and increase in terrigenous discharge source asinferred by anoxic to suboxic iron - sulfate-reducing conditions and lithologicalchange respectively. Both sources referred to some of environmental conditionsassociated with Paleocene - Eocene thermal maximum events such as methanedissociation, water stratification, enhanced hydrological and weathering cycles.
