| Abstract: | On the basis of X-ray diffraction analysis of Ceshui Formation coal and its roof mudstone in the Lianyuan coal basin, it is concluded that telemagmatic metamorphism is the main factor leading to the metamorphism of the Ceshui Formation coal in the study region, which has a great impact on the chemical structure of the Ceshui coal series, and the dynamometamorphism is of local and secondary importance. |
