云南金平县新安里铜镍矿成矿规律与外围找矿

THE METALLOGENETIC RULE AND PERIPHERY PROSPECTING OF XINANLI CU-NI DEPOSIT IN JINPING,YUNNAN

新安里铜镍矿属产于超基性岩中的熔离铜镍硫化物矿床,矿体赋存于基性—超基性岩体中,岩体分异较好、岩相分带清楚,物、化探组合异常与岩体、矿体对应较好。通过对比,新安里铜镍矿成矿规律与已知的营盘Ⅰ、Ⅱ号杂岩体铜镍矿床相似,岩浆分异程度高,推测新安里岩体深部应为地质找矿的有利部位。

Xinanli Cu-Ni deposit is an immiscible Cu-Ni sulfide deposit in the ultrabasic rock, orebody in the basie-uhrabasic rock body. The differentiation of rockbody is good, with the clear zonation. The correspondence of geophysical-geochemical exploration composite anomaly and rockbody-orebody is good. According to the compar- ison, the metallogenesis rule of Xinanli Cu-Ni deposit is similar to the Cu-Ni deposit of complex Yingpan, Ⅱ , The magmatie differentiation degree is high. We infer that the deep part of Xinanli rockbodv must be advantageous to the prospecting.
