Short summary
This study evaluates leucogranites from the Ama Drime Massif, Dinggye, Tibet, as a potential raw material for high-purity quartz. Petrographic, geochemical, and purification analyses of two representative samples show that the rocks are mainly composed of quartz, albite, and K-feldspar. After purification, the quartz reached SiO₂ contents of 99.996 % and 99.995 %, indicating promising potential as a supplementary high-purity-quartz resource.
