本文通过对中条山铜矿田电气石和电气石岩地质产状、岩相学和矿物学、矿物化学等特征的研究,指出本区有三种成因类型的电气石:(1)北峪酸性侵入体岩浆期后热液成因电气石;(2)中条群地层中变质热液形成的电气石;(3)赋矿岩石和近矿围岩中热液蚀变电气石。第(3)类电气石具有特征的产状、矿物化学和矿物共生组合标型,是重要的找矿标志
In this paper, the tourmaline and tourmaline rocks in Zhongtianshan copper field are characterized by geology, lithofacies, mineralogy and mineral chemistry. It is pointed out that there are three types of tourmaline in this area: (1) Body tourmaline geothermal tourmaline origin tourmaline; (2) Zhongzhong group formation metamorphic hydrothermal tourmaline; (3) ore-bearing rocks and near-mine rock hydrothermal alteration tourmaline. Class (3) tourmaline has a characteristic occurrence, mineral chemistry and mineral symbiotic combination of type, is an important indicator of prospecting
