对斑岩铜矿床不断进行的勘探和研究提供了越来越多的事实,证明在这些矿床的深部,非常广泛地分布着深成的硬石膏,这种硬石膏的存在与矿床的矿物和地球化学的分带性某些重要的特点有关系。 现有有关硫化物和深成硫酸盐,首先是硬石膏,在热液金属矿床中分布的资料表明,这些矿物存在着一定的空问-时间关系,它表现在硫化物-硫酸盐分带上。在斑岩铜矿床中存在的这种分带特征引起了人们的特殊兴趣,因为在这些矿床中可以特别清楚地观察到热液形成物与一定岩浆岩体的真实联系。
The ongoing exploration and study of porphyry copper deposits provide a growing body of evidence that deep, very deep anhydrite is distributed in the depths of these deposits and that the presence of anhydrite is associated with mineral and Some important features of zonation of geochemistry are related. The available data on the distribution of sulphides and deep sulphates, first of all anhydrides, in hydrothermal metallogenic deposits suggest that there is a certain spatiotemporal-temporal relationship between these minerals and is manifested in sulphide-sulphate zonation. This banding feature that exists in porphyry copper deposits is of particular interest because the true association of hydrothermal formations with certain magmatic rocks can be clearly observed in these deposits.
