摘要
The three most important elementary factors for the formation of large-super large magmatic sulfide deposits are that 1) large amount of mantle-derived magmas participate in the formation of the deposits, that 2) magmatic evolution results in sulfide immiscibility, and that 3) the sulfides concentrate in a limited space. In this paper, the authors attempt to demonstrate the general features, formation mechanism and geological background, and significance of the magmatic sulfide deposits occurring in magmatic conduit system, which are very important for the further researches and exploration of this type of magmatic sulfide deposits.
