伊利石广泛存在于铜厂大型斑岩铜矿床内,是特征的热液蚀变矿物,其结晶度(IC)和膨胀层含量受携带矿质的热液流体量控制。以浸染状强矿化为特征的斑岩体中上部及接触带附近伊利石结晶程度较好,主要是高水/岩比作用的结果。同时指示出伊利石结晶程度好的部位,矿化品位高,蚀变程度也强。在低水/岩比、流体量小的深部斑岩体内,伊利石结晶度(IC)则主要受温度、时间控制。
Illite is widespread in the copper plant large porphyry copper deposit and is a characteristic hydrothermal alteration mineral whose crystallinity (IC) and intumescent content are controlled by the amount of hydrothermal fluid carrying minerals. The upper part of the porphyry body characterized by disseminated strong mineralization and the illite crystallized near the contact zone are better, mainly as a result of the high water / rock ratio. At the same time indicate the degree of illite crystallization of the site, high grade mineralization, alteration is also strong. The illite crystallinity (IC) is mainly controlled by temperature and time in deep porphyry with low water / rock ratio and small fluid volume.
