Research on Sedimentary Facies and Paleoenvironment of Fentou Formation, Middle Silurian in
In the research area, Fentou Formation of Middle Silurian exposes widely with horizon steady. Lithologically mainly with yellow-green layered quartz sandstone, yellow-green silty mudstone, quartz sandstone, variegated thin siltstone, silty mudstone and lithic sandstone, including a higher clay content were found. The research indicates three types of sedimentary facies, which includes tide-controlled continental shelf facies, continental shelf facies and tidal flat facies chronologically.
