| 摘要： |
| 金川铜镍矿床是世界第三大铜镍硫化物岩浆矿床,现有研究表明其成矿模式为岩浆通道成矿,但是对于金川超基性岩体的侵位过程存在较大争议。为探索岩体的侵位过程,将岩浆侵位描述为马尔可夫（Markov)过程,提出一种基于Markov链的岩体侵位模拟算法,实现对金川超基性岩体侵位过程的模拟。以金川Ⅱ矿区为例,探讨了侵位过程与矿化的关联及岩浆通道骨架,为在矿床深部寻找第二成矿空间提供方向和线索。 |

| Abstract: |
| The Jinchuan Cu Ni deposit is the third largest Cu Ni sulfide magmatic deposit in the world. Previous research shows that the formation of this deposit depended on a magma conduit system. However, there is still great controversy over the emplacement process of the ultrabasic pluton. Thus, this work proposed a simulation method of the magma flow trajectory by regarding the magma flow as a Markov process. Taking the ore district No. II of Jinchuan deposit as an example, the correlation between the emplacement process and mineralization, and the magma conduit skeleton were discussed, which may provide direction and evidence for discovering new metallogenic space in deep areas. |
