In Bajestan region, as can be seen in its geological map (Ashouri et al; 2008), the Late Cretaceous deposits with very low thickness of Sardar and Jamal formations are only depositional
sediments that are exposed in the Bajestan region and also igneous and metamorphic rocks can be seen in the some parts of studied region.
The prevalent depositional
carbonate component of both matrix and grain phases of oil shale is calcite (Table, Fig.

4 m, signifying the gradual cessation of mangrove type vegetation and related mangrove type depositional
environment from 2.
The aim of this work is to test the potential of REE compositions of vertebrate microremains from Ohesaare beds as a source of geochemical information and proxy to early depositional
137]Cs inventories from erosional to depositional
areas; that is, SOC and TN increased with increasing [sup.
On the basis of the distribution of the foraminifera and vertical facies relationships, three major depositional
environments have been identified in the Early to Middle Miocene succession of the Khamir section.
beginning with an overview of the seismic reflection method in general and its limitations, two major sections focus on the description of seismic stratigraphic techniques themselves--including a manual of basic observations, terminology and classification of seismic facies units and a chapter on well calibration and control--and on the depositional
environment and facies interpretation.
6, formula given by Folk (1968) is one of the most useful methods to determine the nature of the sorting of sediments; its application provides information regarding the effectiveness of the depositional
medium in separating the grains of different classes.
Thus the gray shales do not represent a uniform depositional
environment, but instead environmental conditions vary in a relatively short distance such as between Location A and B.
The JIP will focus on the following key issues: relationships between facies, depositional
sequences and reservoir quality; shale pore types and their effect on total porosity and permeability; porosity-permeability trends for individual Utica and Point Pleasant facies; relative permeability and capillary pressure behavior; and linking core-derived reservoir quality to well logs and well productivity.
2003; Raymond, 1995), the results of their microscopic study, XRD analysis and field observations have been used to interpret the paleoweathering, genesis, provenance and depositional
environments of the Hangu Formation.
