华北地台是我国矽卡岩铁矿和金矿的主要产地,并都与一定的中生代岩浆岩有成因联系.报告系统地从岩浆岩建造,岩浆成因角度探讨内生金属矿床的关系.报告对本区中生代侵入岩进行岩浆岩分区,并论述其岩石组合、岩石化学特征、痕迹元素待证;从区域上地幔深度(地壳厚度)与岩浆建造分布的关系;侵入岩的某些成因标志来探讨本区中生代岩浆岩的成因,同时阐述了岩浆岩成因系列与内生金属矿床组合的关系.
The North China platform is the main origin of China’s skarn iron ore and gold mines, and all are associated with some Mesozoic magmatic rocks. The report systematically explores the relationship between endogenous metallogenic deposits from the perspective of magmatic rock formation and magmatic origin The Mesozoic intrusive rocks are divided into magmatic rocks, and their rock assemblages, petrochemical characteristics and trace elements are discussed. The relationship between the depth of the upper mantle (crustal thickness) and the distribution of magma and the origin of some intrusive rocks The Mesozoic magmatic rocks in the area, and also illustrates the relationship between the series of magmatic rocks and the assemblage of endogenic metallogenic deposits.
