Abstract

At the end of the last century developed quantitative conversion of sediment. This proportion and the relative ratios of disturbance of rock-forming grains. They are indicators of stress state of rock. Develop indicators of temperature change of sedimentary rocks, without the involvement of organic matter. Developed and patented a method of determining the degree of sorting rocks. Describe and explain the mechanism of formation sutures and stylolites contacts. New patterns and indicators to accurately determine the conditions of relatively secondary transformations of rocks and sediments in general, in particular. On the basis of their confirmed results of geophysical studies pointing to the rise deposits of Donbass, possibly as a result of introduction of the mantle diapir. Analysis coalbed distances to the base and between the reservoirs revealed that the temperature gradient in the carboniferous was approximately two times higher (than mentioned in earlier papers). Developed geothermal model of gradual cooling of the earth’s crust in increments of 350 million. Years. In accordance with this model, the geothermal gradient Carboniferous was twice as high. The main result of the developed model is the tendency to reduce the surface temperature of the Earth over time, and this process occurs slowly enough.

Keywords
