我们在含矿石英脉型钨-锡矿床上进行了包裹体地球化学找矿试验研究,现将所得的试验结果介绍如下. 地质概况该矿床位于广东阳春地堑式复式向斜西南端核部,地层为下侏罗统砂岩、板岩,矿体周围受角岩化,矿床受两组裂隙控制(北西西、北东东).地表细脉带往深部逐渐变为平行侧幕式排列的含钨石英脉组成工业矿体.矿脉主要产于燕山四期隐伏的花岗岩与砂岩、板岩接触的内外带,矿脉两侧发育不同程度的蚀变,如云英岩化、黄玉化
We carried out the inclusion geochemical prospecting experiment on the ore-bearing vein-type tungsten-tin deposits, and the results of the experiments are as follows: Geological background The deposit is located in the southwest tip of the Yangchun graben syncline in Guangdong, The strata are sandstone, slate and ore body surrounding the lower Jurassic, and the orebodies are controlled by two sets of fractures (North West, North East, East). The surface veins gradually become parallel with the side curtain arrangement Tungsten quartz veins make up industrial orebodies, and the veins are mainly produced in the inner and outer belts of the Yanshan Phase IV buried granite and sandstone and slate. Different degrees of alteration are developed on both sides of the veins, such as Yunyanization, Topaz
