内蒙古阿拉善盟雅干地区岩浆分异型铜镍矿化特征与综合找矿信息提取

Mineralization characteristics of magmatic differentiation type Cu-Ni deposit and integrated prospecting information extraction in Yagan Alxa of Inner Mongolia

经过多年的地质研究,在内蒙古阿拉善盟北部雅干地区发现部分基性岩浆岩中具有铜镍钴多金属矿化.采用地质调查研究、激电中梯测量、激电测深、高精度磁测、地球化学数据采集、探矿手段验证,初步认为矿化与基性辉长岩体关系密切,成因主要为基性岩浆分异形成.辉长岩既是矿体赋存母岩又是控矿的主要因素.初步确立了找矿信息提取标志.研究成果对相似相邻区域铜镍钴找矿有参考意义.

After many years of geological research, it has been found that there is polymetallic mineralized Cu-Ni-Co in part of mafic magmatite northern YaGan area of Alxa Inner Mongolia. The geological survey and study, IP intermediate gradient measurement, the IP sounding, high precision magnetic, geochemical data acquisition, and the prospecting method verify that the mineralization and basic gabbro rock mass are closely related, the main causes for the mafic magma formation. The gabbro is the orebody rock is the main ore controlling factors. The prospecting information extraction of mark has been initially established. Research on the similarity of adjacent area Cu-Ni-Co ore has important guiding significance.
