Preliminary Petrography of the Hangu Sandstone, Hangu, Kohat
Abstract
The guartzitic sandstone of the Hangu Formation is mature both texturally and mineralogically. The detritus is diagenetically cemented by secondary silica giving rise to interlocking texture. The petrography and stratigraphic position of the sandstone suggests shallow marine environments of deposition where feldspar, lithic fragments and other softer material were completely destroyed us a result of repeated winnowing by long shore currents, while quartz and a resistant suite of heavy minerals were retained.
