Mametova L. Structurally-mineralogical transformations of gas-bearing sandstones of Donbassis

Work is devoted to research of sandstone's postsedimental transformations of river-bed facies in the southwest, central and northeastern districts of Donbasin. Detailed petrography researches of sandstone's minerals with determination of their structure microdeformation types, appearance of which induced by tectonic processes in ac-companiment of one mineral and formation dissolution reactions of other are carry out. Intercommunication certain types of microdeformations and character of the de-forming processes fixed by the minerals of sandstones and their concordance with a tectonic structure, stages of pool development has being established on the basis of their distribution analysis. The result of carbonates and other mineral research was been presented and their influencing on collecting property has being determined. Application of the terms reconstruction methods of deformation just on the pre-liminary stage of geological works will allow to estimate the physical condition of mountain massif and to heave up of miners work safety level.
