The Jeribe Formation in Well Kor Mor /3 is divided into two microfacies and five submicrofacies identified on the basis of different sedimentological and paleontological criteria.
The first microfacies is lime mudstone which is divided into two submicrofacies: Algal lime mudstone and planktonic foraminiferal lime mudstone, while the second microfacies is fossiliferous lime packstone which is divided into three submicrofacies: Miliolidal lime packstone, pelecypodal lime packstone and echinodermal lime packstone. On the basis of facies properties, sedimentological and paleontological
characteristics, the depositional environments were established. These contain spectrum of depositional sites from inner lagoon to supratidal environments.

The present study deals with the biostratigraphy of the Aquitanian -Lower Early Langhian successions age in Kor Mor well No.3 at Kirkuk area.
The studied section includes six formations with a total thickness of about (430) meters.These are: Ibrahim, Azkand, Anah, Euphrates, Dhiban and Jeribe formations.
Eighteen species and subspecies of planktonic foraminifera and twenty one species and subspecies of benthonic foraminifera are recognized.
Also some forams of benthonic foraminifera to the genus level are identified.
Fragments of mullosca shell, echinoderm, green and red algae were recognized from the studied succession.They permit an identification of five biostratigraphic zones and are from younger to older:
Borelis melo curdica Total Taxon - Range Zone.
Miogypsina globulina Total Taxon - Range Zone.
Miogypsinoides complanatus Total Taxon - Range Zone.
Catapsydrax dissimilis Partial - Range Zone (N.5).
Globigerinoides primordius Partial - Range Zone (N.4).
The first two zones are withen Ibrahim Formation, of Early Miocene (Early Aquitanian) age.Whereas, the third zone affilated to Azkand and Anah formations of Early Miocene (Late Aquitanian) age,The fourth zone is related to Euphrates and Dhiban formations of Early Miocene (Late Burdigalian) age. The last zone represent Jeribe Formation of Middle Miocene (Lower Early Langhian).

تشمل صخور فترة البرديكالين (Burdigalian) على تكويني الفرات والذيبان مع تداخلات لطبقة من تكوين سريكاكني ضمن تكوين الفرات. قسمت صخورالتكوينات الى سبعة سحنات رئيسية وسحنتين ثانويتيين وسحنة صخرية واحدة اعتماداً على المظاهرالرسوبية والمكونات الحياتية، والسحنات الدقيقة لتكوين الفرات هي سحنة الحجر الجيري الطيني- الواكي الحاوي على الطحالب و سحنة الحجر الجيري الواكي- المر¬صوص الحاوي على الطحالب وسحنة الحجر الجيري المرصوص- الحبيبي وسحنة الحجر الجيري الحبيبي الحاوي على السرئيات فضلاً عن سحنة الحجر الجيري الطيني الحاوي على الفورامنيفرا الطافية والتي تمثل تداخل تكوين سريكاكني مع تكوين الفرات، ويشمل تكوين الذيبان على سحنة الحجر الجيري الطيني و سحنة الحجر الجيري الحبيبي الحاوي على المليوليد و سحنة الانهايدرايت الصخرية. من خلال مواصفات هذه السحنات والدلائل الحياتية ولاسيما الفورامنيفرا و الطحالب، تبين ان صخور فترة البرديكالين تضم طيفاً واسعاً من البيئات الممتدة من بيئة اللاكون الخارجي ولغاية بيئة فوق المد.

Facies Analysis and Sedimentary Model of Burdigalian Stagein Kor Mor Well No.3, Kirkuk Area-Iraq

The present study describes the sucessions of the Burdigalian stage, which includes: Euphrates, Dhiban Formations and intervening of Serikagne Formation with Euphrates Formation.
Numerous microfacies are identified, based on different criteria. The microfacies of Euphrates Formation are: algal lime mudstone - wackestone, algal lime wackestone - packstone, lime packstone-grainstone, oolitic lime grainstone, and planktonic foraminiferal lime mudstone which represent the intercalation of Serikagne Formation with Euphrates Formation.
The microfacies of Dhiban Formation are: lime mudstone, miliolidal lime grainstone and anhydrite lithofacies.
On the basic of their properties and other sedimentary and biological features, the depositional environments are inferred. These contain a spectrum of depositional sites from outer lagoon to supratidal environments.
