锡(有时是钨)矿化与钽铌矿化在空间上的联系,在找矿中已引起重视.目前已知的钽铌花岗岩型矿床,总是分布在锡(或钨)矿成矿区内,并常见有一种固定的分带性,表现在:钽铌矿化产于岩体顶部,而锡(或钨)矿化常出现在岩体附近或岩体顶部外接触带的脉体中.根据这一规律,研究锡石(或黑钨矿)的含钽性,对预测隐伏含钽铌花岗岩,在普查找矿中有着极其重要的意义.本文是根据作者在某一矿区进行钽铌花
The spatial relationship between tin (sometimes tungsten) mineralization and tantalum-niobium mineralization has drawn much attention in prospecting. The tantalum-niobium-granitoid deposits are now commonly found in the tin (or tungsten) mineralization , And there is a common zonation typical of tantalum-niobium mineralization at the top of the rock mass and the tin (or tungsten) mineralization often occurs in the vein of the rock mass or in the outer contact zone at the top of the rock mass. According to this law, studying the tantalum content of cassiterite (or wolframite) is of great significance for the prediction of concealed tantalum-niobium granite, and is of great significance in the prospecting of censuses.According to the authors’
