Abstract
The micromorphological and microchemical investigations of the clinopyroxene grains collected from the fine sand fraction in the surface horizon of the Khurrianwala Soil Series revealed the microtextural features: 1) irregular and elongated grains, 2) needle and lenticular shaped overgrowths, 3) parallelism of striations to C direction, 4) dissolution pattern, 5) etching pattern, 6) Si-coatings, 7) cellular humps, and 8) oriented dish shaped pattern. The presence of c1inopyroxenes in the heavy fraction of the fine sand suggests that mafic igneous rocks have contributed to the soil parent material. Submicroscopic investigations of the c1inopyroxcne grains revealed the solution, precipitation/overgrowth and etching as the main shaping mechanisms of minerals. It is also concluded that mineral shape under SEM could provide information about the sedimentary history ..
