广西钨钼矿成矿规律

广西地处古中国构造域南端,是中国著名的有色金属基地,钨钼资源较丰富。广西钨钼矿矿床类型以热液脉型和矽卡岩型为主,成矿时代分布较广,包括加里东晚期、印支晚期及燕山晚期,区内大型钨钼矿床主要成矿于燕山期。钨钼矿床的空间分布与构造和岩浆岩关系密切,区域性断裂和富含W、Mo等成矿元素的复式岩体对成矿更加有利。本文对广西区内主要钨钼矿床进行了梳理,总结了广西钨钼矿成矿规律,并以典型钨钼矿床特征为依据,划分了11个矿床成矿系列,对区内下一步找矿具有指导意义。

Metallogenic regularities of tungsten and molybdenum deposits in Guangxi

Guangxi is located in the southern part of the ancient Chinese tectonic domain, it is a well-known non-ferrous metal base in China. Guangxi Province is relatively rich in tungsten and molybdenum resources. The types of deposits in Guangxi Province are mainly hydrothermal vein type and skarn type. Tungsten and molybdenum mineralization ages are widely distributed in Guangxi Province, including the late Caledonian, late Indosinian and late Yanshanian period. The large tungsten and molybdenum deposits in the region were mainly formed in the Yanshanian period. The spatial distribution of tungsten and molybdenum deposits is closely related to structure and magmatic rocks. Regional faults and compound rock masses rich in W, Mo and other metallogenic elements are more favorable for mineralization. This paper sorts out the main tungsten and molybdenum deposits, summarizes the metallogenic regularities of tungsten and molybdenum deposits in Guangxi Province, and divides 11 deposits metallogenic series on the basis of the characteristics of typical tungsten and molybdenum deposits, which has guiding signi.cance for the future prospecting in Guangxi Province.
