| 中文摘要:新安里镍矿经过四年的勘查工作, 探获一中型镍矿床。新安里镍矿位于金沙江—哀牢山板块结合带南段之金平断块中, 产于基性-超基性岩体内, 矿体呈似层状、透镜状产出。通过区域地质特征、矿床地质特征、矿体地质特征分析, 矿床成因类型初步认为属产于超基性岩中的熔离铜镍硫化物矿床, 找矿标志为岩体分异程度、构造条件、物化探异常。有助于在云南其它地区基性-超基性岩中寻找同类型镍矿床。 |

| Abstract:Through four years’ exploration, a medium-size nickel deposit was discovered in Xin’anli area. The Xin’anli nickel deposit lies in Jinping fault block along the southern segment of the Jinshajiang-Ailaoshan plate juncture zone, and occurs in the basic-ultrabasic rock body, with the ore bodies assuming stratoid and lenticular forms. Based on an analysis of regional geological characteristics, ore deposit features and ore body features, the authors preliminarily hold that the ore deposit should genetically belong to the liquation Cu-Ni sulfide type, and that the ore-prospecting criteria include differentiation degree of the rock body, the structural conditions and the geophysical-geochemical anomalies. The results obtained by the authors are helpful to the prospecting for nickel deposits of the same type in basic-ultrabasic rocks in other areas of Yunnan Province. |
