广西的锡矿资源丰富,其矿床类型多,成矿条件比较复杂。其中珊瑚钨锡矿在广西锡矿生产中占有重要地位。认识珊瑚钨锡矿的分布规律及其成矿特点,对加强广西的锡矿普查找矿工作将会有重要的现实意义。1广西锡矿床的分布规律1.1锡矿的成矿期本区锡矿成矿期主要为四堡-雪峰期、加里东期、燕山早期和燕山晚期四个岩浆成矿期,海西-印支期亦有小规模成矿。
Guangxi is rich in tin deposits, with many types of deposits and more complicated metallogenic conditions. Coral tungsten and tin mine in Guangxi tin production occupies an important position. Understanding the distribution rules of coral tungsten-tin deposits and their metallogenic characteristics will have important practical significance for strengthening the prospecting work of tin deposits in Guangxi. 1 Distribution of tin-bearing beds in Guangxi 1.1 Tin mineralization period The tin mineralization stages of this area are mainly four magmatic mineralization stages, namely, Silbao-Xuefeng period, Caledonian period, early Yanshanian period and late Yanshanian period. The Hercynian- There are also small-scale metallogenic stages.
