| Abstract: | Coal beds of C -P coal measure in Xinzh eng mining area,there are propertie s that coal types much many,metamorp hic grade on the high side,and higher in north,lower in south,and distributed in sh ape of belt.The paper emphatically p robe into metamorphism type,and counted the metamorphic te mperature as main influence factor a nd simulated the evolutionary proce ss of metamorphism. |
