The coal forming period of Carboniferous is mainly located in the late Carboniferous Epoch, forming the coal measure strata in the North China, East China and central-south China. During the early Permian Epoch, the coal measure strata of Shanxi formation was formed spanning large area of North China, while during the late Permian Epoch, the ...P916075.

Atlas of Palaeogeography and Lithofacies, Geological Society of London Memoir, No. 13). coal-measure source rock were proposed from both qualitative and (semi-) quantitative aspects. That is to say, a method for (semi-) quantitative predictions of the distribution ranges of coal-bearing intervals based on model wave impedance inversion and neural network wave impedance inversion, along with a method for (semi-) quantitative ...

The prediction and development of three gases, mainly coalbed methane, shale gas, and tight sandstone gas, in the Huainan coal measures of China, has been the focus of local coal mines.
