摘要
非金属矿床含矿建造是在特定构造环境中,由岩浆侵入和喷出、沉积、风化残留、变质而堆积的具有成因上相关和有联系的特征岩类和特殊的非金属矿含矿性的岩石的共生组合。一定的非金属矿种和它们的一定的成因类型矿床常常赋存在一定的含矿建造中。研究非金属矿床的含矿建造可以更好地了解非金属矿床的形成、分布和出现各矿种之间共生伴生组合关系(成矿系列)的内在规律以指导资源勘查工作。根据已掌握的中国资料可以划分出36种非金属矿床含矿建造。
An ore formation of nonmetallic mineral deposits is an association of genetically related characteristic rocks formed by magmatic intrusion and extrusion,deposition,weath- ering and metamorphism in a particular tectonic setting and rocks with particular specialization of nonmetallic miuerals.A specific variety of nonmetallic minerals and a specific genetic type of their deposits often occurs in a specific ore formation.The study of ore formations of nonmetallic mineral deposits may contribute to the better understanding of the inherent low governing the formation and distribution of nonmetallic mineral deposits as well as the appearance of different paragenetic and associated assemblages of various types of nonmetallic minerals so as to provide guidance to the work of resource exploration.According to the available data of China,36 groups of ore formations of nonmetallic mineral deposits can be distinguished.
