Stratigraphy and paleontology of coal beds in the Ghazij Shale, Sor Range-Daghari Coal Field, Quetta Division, Pakistan

Coal mine tunnels and surface sections in the Ghazij Shale of early Eocene age in the coal field near Quetta, Pakistan, were sampled in detail in order to make a foraminiferal analysis. This analysis and consequent correlations suggest that the coal seams are lenticular and have little lateral continuity. The planktonic Foraminifera date the geologic age of the coal-bearing sequences as early Eocene. Other Foraminifera indicate the shallow-water environment of deposition of the coal. Evidence is presented to show that coal was deposited in a series of unconnected swamps or marshes.
