M.R. Khan Edward B. Fritz 1975 <p>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.</p> application/pdf 10.3133/ofr75274 en U.S. Geological Survey Stratigraphy and paleontology of coal beds in the Ghazij Shale, Sor Range-Daghari Coal Field, Quetta Division, Pakistan reports
