喀拉通克1号铜镍硫化物矿床研究

ON KARATUNGKE No.1 Cu-Ni SULPHIDE DEPOSIT

本文通过大量的测试研究.对喀拉通克1号铜镍硫化物矿床的围岩、构造、岩石矿物,矿石及同位素地质等特征进行了详细的阐述.该矿是由上地幔亚碱性拉斑玄武岩浆经中间岩浆房液态层状分异后,侵位于活动区,其中的含矿岩浆就地熔离成矿,同源矿浆贯入成矿,以及它们复合定位所形成的岩浆熔离叠生矿床.并建立起该矿床的成岩成矿模式.

Through tremendous studies on Karatungke No.l Cu-Ni sulphide deposit, the characteristics of countryrock, structure, petrology and mineralogy, ores and isotopic geology are described in details in this paper. This deposit was formed by repeated melting and dissociating of ore magma with composite emplacement which came from sub-alkalic tholeiite of upper mantle undergoing stratiform differentiation in a liquid state in the middle magma house and intruding into the active zone. Its diagenetic and minerogenetic models are also built up.
