Microstructure Investigation of the Leucratic Granites of the Kargaliiskoe Deposit.

The chemical-mineralogical composition of local leucocratic granites from the Kargaliiskoe ore deposit was studied. Petrographic and scanning electron microscopic analyses were used to investigate the microstructure. Leucocratic granite consists mainly of the minerals microcline, albite, and quartz; it is a valuable nonmetalliferous ceramic raw material, which can replace imported deficit feldspar materials use in ceramic bodies.
