    Annotation The Upper Triassic sandstones of gas-oil reservoirs of Euphrates Graben in Syria are characterized by certain mineralogical characteristics, conditioned by the processes of sedimentogenesis and diagenesis. In the course of the analytical work, it was possible to establish the nature of minerals composing sandstones and their impact on the porosity of rocks. So, for example, a good sorting of detrital grains and their substantial quartz composition is an important factor determining the increased values of porosity. On the other hand, the increased content of clay and authigenic minerals (more than 10-15%) reduces the porosity of rocks studied. Methods of optical microscopy, X-ray diffraction, electron microscopy and chemical analysis were used when describing sandstone. It is shown that the studied sandstones are quartz. Clay minerals, authigenic quartz and carbonates with a small fraction of amorphous material serve as cementitious material of detrital grains. Studies with a scanning electron microscope in conjunction with dispersive X-ray spectroscopy have shown that quartz is clastic and amounts to an average of 70%, and up to 10% of authigenic quartz is also present in the samples. The same studies show differences in the morphology of quartz, which are found in all samples.
