Minemlogical investigation of the feldspar sand grains collected from the fine sand fraction of the KJuarianwala K-feldspar. Muscovite has been found to be much more common constituent than biotite. The abundance of light minerals was quartz (dominant), Na-Feldspar (major), illite (mica) and K-feldspar (minor) and calcite (traces). Microtextural determination of feldspar grains revealed the following features: 1) elongated and rounded irregular shapes; 2) etched suiface morphology; 3) silica coatdings at the grain suiface; 4) an overgrowth of tubfular and lenticular ciystdals; 5) rough givin suiface; 6) embedding of lenticular crystals under silica coatings; 7) seirated outer boundary of the grain and 8) stepped cleavage pattern. These features revealed the solution, precipitation, overgrowth, etching and cleavage planes as the main shaping mechanism of feldspar sand grains in the suiface layer of a Typic Saloilhid.
