| 摘 要： | 母岩浆侵入现存空间之前，在深部就已发生了熔离作用和部分结晶作用，致使母岩浆分离为不含矿岩浆、含矿岩浆、富矿岩浆和矿浆，然后对现存空间一次或多次贯入成矿。这种成矿作用是小岩体成大矿的必备条件，这种深部熔离—贯入矿床，是中国最主要的岩浆硫化物矿床类型，也是世界主要的岩浆硫化物矿床类型之一

| Abstract: | Before intruding,parent magma experiences liquation and partial crystallization in depth so that the parent magma is partitioned into barren magma, ore bearing magma,ore rich magma and ore pulp,then injecting into present locations by one or multiple times and forming deposits.This mineralization is necessary for small intrusions to form large deposits.The deep seated magmatic liquation injection deposit is not only a main deposit type in China,but one of major sulfide deposits in the world. |
