我们为配合广东区域地球化学普查和成矿预测,初步研究了广东西部W、Sn、Cu、Mo、Pb、Zn等六个矿床的地球化学特征和元素分带模型.1.矿床类型简介所研究的矿床有如下六个类型:(1)南山钨矿:属气成高温热液充填型石英脉钨矿床,成矿母岩为隐伏的细粒斑状花岗岩,矿体主要产在下侏罗系的角岩化砂、板岩中.(2)锡山锡矿:为高温热液型石英脉和云英岩型锡石一黑钨矿床,矿的形成与晚期微细粒钾长花岗岩有关,矿体赋存在早期的钾长花岗岩中.
In accordance with the regional geochemical census and ore-forming prediction in Guangdong, we have initially studied the geochemical characteristics and elemental zonation patterns of six mineral deposits such as W, Sn, Cu, Mo, Pb and Zn in western Guangdong.1. There are six types of deposits: (1) Nanshan tungsten ore: a gas into a high temperature hydrothermal filling type quartz vein tungsten deposit, metallogenic host rock for the hidden fine granuloid granite, the ore body is mainly produced in the lower Jurassic angle Petrified sand and slate. (2) Xishan tin deposit: It is a high-temperature hydrothermal quartz vein and a dolomitic cassiterite-wolframite deposit. The formation of the ore is related to the late-stage fine-grained K-bearing granite. Early potassium in granite.
