| 摘 要： | 青海玛沁县友后青地区大地构造位置处于阿尼玛卿缝合带内,在友后清地区发现了与基性-超基性岩体关系密切的钴铜矿化带。本文主要分析了友后青地区钴铜矿化带的成矿地质特征,认为华力西-印支期NW-NWW向的深大断裂控制着钴铜成矿作用。高精度磁测显示,区内有一条近NWW走向的磁异常带,异常强度中等偏高,呈串珠状分布。水系沉积物测量表明,以镍钴铬为主的多金属综合异常规模大,元素组合齐全,镍钴铬元素异常套合好。水系沉积物地球化学异常与高精度磁测异常可以很好的叠合在一起,在空间上与基性-超基性岩关系密切。沿NW-NWW向断裂带,与基性-超基性岩叠合较好的物化探异常区是该地区寻找钴铜矿的有利地段。

| Abstract: | The Youhouqing area is located in the Animaqing suture zone, and large-scale mineralized zones are found in the ophiolitic mélange belt. This paper mainly analyzes the favorable sites of the Co-Cu deposit in the Youhouqing area. The study shows that the Variscan-Indosinian NW-NWW trending deep-large faults have controlled the Co-Cu mineralization. The high-precision magnetic measurement shows that there is a NWW-trending magnetic anomaly zone in the study area, with medium to high anomaly intensity and beaded distribution. The geochemical measurement of stream sediments shows that the comprehensive anomalies of Ni, Co and Cr are large in scale, complete in element assemblages and well integrated in Ni, Co and Cr anomalies. Geochemical anomalies of stream sediments and high-precision magnetic anomalies can be well overlapped and closely related to basic-ultrabasic rocks. Along the NW-NWW trending fault zone, the geophysical and geochemical anomaly areas with good overlap with basic-ultrabasic rocks are favorable areas for the exploration of cobalt-copper deposits in this area. |
