摘要
湖南省锡矿资源丰富,全省共查明锡矿产地67处,探明锡金属量超过200万吨。前人研究主要针对单个矿床开展,缺乏对湖南省锡矿成矿规律的系统研究。本文通过全面收集整理湖南省锡矿的勘查和研究资料,系统总结了湖南省锡矿的成因类型、成矿地质条件、成岩成矿时代与物质来源等方面的特征,认识到湖南省经历了加里东期—印支期—燕山期多旋回的锡矿成矿作用,锡矿的形成与富含Li、F、W、Sn等微量元素的高分异花岗岩关系密切,成矿物质主要源自地壳中的中元古代沉积岩,部分矿床的成矿过程可能有幔源物质参与。
Hunan province is rich in tin mineral resources,with a total of 67 identified tin deposits and a proven tin metal reserves exceeding 2 million tons.Previous studies mainly focused on individual deposits,lacking systematic research on the mineralization patterns of tin deposits in Hunan province.This article comprehensively collects and organizes exploration and research data on tin deposits in Hunan province,systematically summarizes the characteristics of tin deposits in Hunan province in terms of genetic types,ore-forming geological conditions,diagenetic and ore-forming ages,and material sources.It is recognized that Hunan Province has experienced multiple cycles of tin mineralization from the Caledonian to the Indosinian and to the Yanshan period,and the formation of tin deposits is closely related to highly differentiated granite rich in trace elements such as Li,F,W,and Sn.The ore-forming materials mainly originate from the Middle Proterozoic sedimentary rocks in the crust,and some ore deposits may have mantle derived materials involved in the ore-forming process.
