| Abstract: | The Middle Jurassic Dameigou Formation is coal-bearing strata in eastern Iqe coalfield belongs to limnetic, lakeshore deposit. Structures in the area are rather complex, faults usually have large throw. Macrolithotype of coal is mainly bright coal - semibright coal, appearing as regional metamorphism, metamorphism degree of coal is rising from shallow to deep, from south toward north. |
