与中酸性岩浆岩有关的矿产有铁、钼、铜、钨、锡、铌、钽、稀土、铍等.岩体中成矿元素丰度在岩体含矿性地球化学评价中的作用,长期以来存在两种观点,即:①认为岩体中成矿元素丰度高,是岩体含矿的标志;②认为岩体本身成矿元素丰度高,未必有利于成矿.本文试图以成矿地质作用为基础,运用元素的基本地球化学性质,对如何根据岩浆岩中成矿元素丰度,进行岩体含矿性地球化学评价,提出几点看法. 成矿元素丰度与成矿作用的关系成矿岩体中成矿元素丰度,按其与非成矿岩体的区别可分为三类:
Minerals related to medium-acidic magmatic rocks include iron, molybdenum, copper, tungsten, tin, niobium, tantalum, rare earth, beryllium, etc. The role of metallogenic abundance in rock mass in ore-bearing geochemical evaluation of rock mass, Since there are two kinds of viewpoints, namely: (1) It is considered that the ore-forming element abundance in rock mass is a sign of ore-bearing of rock mass; (2) It is considered that the mineralization of rock mass itself is high, which may not be conducive to metallogenesis. Based on the geological features of the ore deposits, the basic geochemical characteristics of the elements are used to evaluate how the ore-forming geochemistry of the ore bodies is evaluated according to the abundance of metallogenic elements in the magmatic rocks. The relationship between metallogenic rock ore-forming element abundance, according to its non-ore-forming rock body can be divided into three categories:
