Abstract:
The Cambrian age khewra formation sandstone is petrographically analyzed in this research.
Detail mineralogy, texture and diagenesis phenomena were studied. The quartz remains the
dominant framework mineral in all sections while feldspar were the second dominant framework
grain. Khewra Sandstone is scarce of lithics fragment revealed in this petrographic analysis. The
percentage of matrixremains higher throughout in all sections and appeared to be directly related
to higher percentages of feldspar as the alteration of feldspar to clay was observed in most of the
thin section it accounts for higher percentage of matrix. The color, alteration and replacement of
minerals and different orientation of grains narrates that the Khewra Sandstone subjected to all
three diagenetic stages. The Khewra Formation lies in sub-arkosic class.
