按照现有的概念,在成矿物质由地球深处搬运上升的过程中岩浆起着主要的作用。阐明岩浆中金属元素的来源对于认识成矿作用很重要。所有岩石学研究都可说明,花岗岩浆按成因可分为两个基本类型:1)由地幔物质选择性重熔而成的玄武岩类岩浆的酸性分异物;2)由地壳物质经再熔作用而形成的岩浆。
According to the existing concept, magma plays a major role in the process of ore-bearing materials being transported and transported from deep into the earth. It is important to elucidate the source of metallic elements in magmas to understand mineralization. All petrological studies show that granite magmas can be divided into two basic types according to their genesis: 1) acidic subdivisions of basaltic magmas that are selectively remelted by mantle materials; 2) Magma formed.
