Features of the Structure of Carbon-Rich Rocks (Based on the Example of the Lower Silurian Sediments of the Sichuan Depression of the Yangtze Platform).

The petrophysical, geochemical, and lithological features of the structure of graptolite shales from the lower part of the Longmaxi Formation of the Lower Silurian age of the Sichuan Province of the People's Republic of China are considered. The basic patterns of the formation of carbon-rich sediments in the intrashelf depressions are revealed. [ABSTRACT FROM AUTHOR]
