| Metallogenic Series, Regularities, and Prospecting Directions of Rare Metal Gemstone Deposits in West Yunnan |
| Using research methods based on metallogenic series deposit theories, this study preliminarily determined the metallogenic series and sub-series of rare metal and gem deposits related to Yanshanian–Himalayan pegmatite and the metallogenic series and sub-series of rare metal deposits related to quaternary supergenesis. The results indicated that large-scale intermediate-acid magmatic intrusions occurred that produced a number of pegmatite rocks and caused significant magma-hydrothermal metallogenic events in the Yanshanian–Himalayan epoch of this area. Rare metal mineralizations, including Be, Nb, Ta, Li, Rb, and Cs, were mainly related to Yanshanian–Himalayan granite and pegmatite and constituted specific rare metal mineral deposits. This study preliminarily described rare metal mineral resources, their characteristics, and metallogenic series deposits and regularities, and analyzed prospecting potential, delineated prospective areas, and deepened our understanding of the metallogenic regularities of rare metals in West Yunnan. |
