Petrographic Characteristics and Depositional Environment of the No. 9 Coal (Pennsylvanian) from the Anjialing Mine,Ningwu Coalfield,China

Abstract

18 coal samples of Coal Seam 9 were taken from the Anjialing Coal Mine, Ningwu Coalfield, Shanxi Province, and were analysed by microscopic method. The results indicate that the macerals are dominated by vitrinite in Seam 9. Six maceral indicies were selected as indicators of peat-forming environments. One diagram is drawn based on the indicators in order to explicate the peat-forming environments of Carboniferous Seam 9. The results indicate that the peat of Carboniferous Seam 9 formed dominantly in the wet swamps and open moors.
