Remote sensing data were employed to study the soil distribution of Late Quaternary deposits in Bashiqa Structure, north of Mosul City. The outcome of this study distinguished three primary classes of soils depending on their morphogenetic origin. Furthermore, the first two classes encompass five subclasses related to its particular site within the study area, and in which the geomorphological factor plays an important role in the spatial distribution of soil forms; thus providings the tools of soil classification distribution map at the scale of 1/50,000.
The map produced is commensurable with the analysis of Landsat imagery at 1/100,000 scale, which resulted in the development of thematic image classified according to the relevant available computer programs. The separation of these classes accomplished through comparison of reflected spectrum of the optical pixels of the images with the spectral signature of each image pixels related to individual class.
The integration and discussion of the results and documentation of the above mentioned classification were ascertained by field and laboratory examinations in order to verify the differences among these classes and to enhance the variability of spectral reflectance from one site to another.

The Ostracode biostratigraphic evidence and the evolutionary trend of Upper Cretaccous-Lower Tertiary Ostracodes are determinated by using the vertical and lateral distribution and the morphological change of the selective genera and species.
Anommatocythere; Brachycythere; Buntonia; Kaesleria; Mehsella; Nucleolina and Protobuntonia.
The evidence determinated by the study of the above taxa of this time showes closely resemblance in their morphalogical features and suddenly disappears during the Upper Cretaceous of the genera:
Brachycythere; Kaesleria; Mehsella; Protobuntonia and other species continue in the Lower Tertiary, Buntonia; Mehsella and Nucleolina. Otherwise species of Anommatocythere show first appear during the Lower Tertiary .

The present study deals with the distribution of major oxides (Al2O3, CaO, Fe2O3, SiO2 wt%), minor oxides (Cl, K2O, MgO, MnO, Na2O, P2O5, TiO2 wt%), trace elements (Co, Cr, Cu, Ni, Zn ppm.) and the consituents of free lime, insoluble residue and loss on ignition in (38) representing different types of portland cement produced at ( 13) Iraqi factories during the interval 1997 / 1998. The study is concerned with variation in the chemical composition in relation to the nature of raw material or raw mix, burning, cooling and storing conditions and the content of major phases in ordinary, sulfate resistance and white portland cement.
