The Discovery and Geological Implications of Pegmatite-Type High-Purity Quartz in the Qinghe Area, Altay
High-purity quartz (HPQ) is a critical strategic raw material for the semiconductor, optical fiber, and renewable energy industries, yet China still faces a shortage of high-grade domestic resources. To systematically constrain the geological characteristics of pegmatite-type HPQ mineralization in the Qinghe area of th...
