本文是多年实际工作的总结,旨在通过对现有资料的分析,划分钨矿床的工业类型,总结其地质特征和成矿规律。文中引用了湖南冶金地质勘探公司二○六队及瑶岗仙矿的一些资料,在此一并致谢。一、钨矿床的工业类型湘南地区位于南岭东西向成矿构造带中段之北缘。区内地层自元古界至第四系基本齐全,构造复杂,岩浆活动频繁,特别是燕山期花岗岩广泛出露。在这特定的地质环境下,提供了钨富集成矿的有利地质条件,使本区成为我国钨矿床重要产地之一。我们根据本区钨矿床的成因、矿体形态、围岩、矿石矿物组合和矿床的工业意义,将本区钨矿床分为五种工业类型(表1)。
This article is a summary of many years of practical work, aimed at the analysis of existing data, the classification of tungsten deposits in the industry type, summarizes the geological characteristics and metallogenic regularity. The article quoted Hunan Metallurgical Geological Exploration Company 206 and Yao Gangxian mine some of the information, together with the thanks. First, the type of tungsten deposits in southern Hunan Province is located in the east-west ore-bearing belt in the middle of the northern margin. The strata in the area are basically complete from Proterozoic to Quaternary, with complex structures and frequent magmatic activity, especially the Yanshanian granites. In this particular geological environment, the favorable geological conditions for the enrichment of tungsten are provided, making this area one of the important places for producing tungsten deposits in our country. We classified the tungsten deposits in this area into five industrial types (Table 1) according to the genesis of the tungsten deposit, the morphology of the ore body, the surrounding rock, the mineral assemblage of the ore and the industrial significance of the deposit.
