Abstract
According to the analysis of micro-characteristics and depositional environment of the main exploit-ed coals, and using the triangular diagram (In the diagram, the significance to indicate coal facies of the minerals in coal, especially authig enicones, has been taken into consideration) and the map of maceral, the authors have found that there is a higher active component and sulfur content in tide-dominated delta plain than that in river-dominated delta plain, and the divergence in the triang ular is small. Besides, the inert component in the coal formed on the tidal flat is high and its distribution is stable, and there is a likeness between different coals formed in the same depositional environment. But there is a difference of microcomposition on the plane because of the various environment.
