Metallogenic series related to Yanshanian granitoids in Tengchong area, Yunnan,China

The Yanshanian magmatic-hydrothermal mineralization formed three ore belts and two important ore concentration districts of Diantan-Dadongchang-Hongyantou lead-zinc-tin-iron-wollastonite deposits and Tieyaoshan-Xiaolonghe tin-tungsten-iron-lead-zinc deposits in Tengchong area. Basing on the previous research and the theoretical methods of metallogenic series, this paper defines the metallogenic series and sub-series related to Yanshanian granitoids and systematically summarizes the spatial-temporal distribution regularity of mineral resources related to Yanshanian granitoids in Tengchong area. The results show that the Yanshanian period is the most critical period for magmatic-hydrothermal mineralization in Tengchong, all ore deposits of tin, lead, zinc, iron, copper, tungsten, gold, silver, pyrite, wollastonite, fluorite, gem, mica, andalusite, rare earth elements, and rare metals are mainly related to the Yanshanian granitoids, forming the specific metallogenic series of Yanshanian granitoids. According to the zonings of granitoids, the spatial distribution of deposits, and ore-forming epochs, the metallogenic series of Yanshanian granitoids in Tengchong area could be further divided into three metallogenic sub-series. By characteristics of the metallogenic sub-series, this paper has summarized and analyzed the potential prospecting prospects in the region. It is hoped that this paper can deepen the understanding of metallogenic regularity of tin (tungsten), lead-zinc, iron, wollastonite, and copper deposits in Tengchong area, providing a reference for geological prospecting, teaching, and scientific research in the future.
