中文摘要:
      驼路沟钴金矿床位于东昆仑金、铜、铅锌、铁、多金属成矿带中的昆南金、铜、钴成矿带内。矿体产于近东西和北北东向2组不同时期断裂的交汇处,属火山喷流沉积-改造型矿床。矿体产于古生代纳赤台岩群中,矿体大多产出在正负磁异常过渡带中的弱磁异常带中,1:5万水系沉积物圈定出以Au、Cu为主,伴生As、Sb、Co等元素的综合异常,异常套合好,三级浓度分带明显,铁染与羟基遥感蚀变异常均有分布,羟基异常多出现在铁染异常的边部。矿床与地物化遥特征均有密切的相关性,综合找矿成果明显,通过全方位研究矿床的相应特征,可对扩大现有矿床规模或在其外围发现新的类似矿产地提供借鉴。
英文摘要:
      The Tuolugou cobalt-gold deposit is located in the Kunnan gold, copper, cobalt metallogenic belt, which belongs to the Eastern Kunlun gold, copper, lead and zinc, iron, polymetallic metallogenic belt. This deposit belongs to volcanic exhalation sedimentation reformation type, and the ore bodies were occurred in the junction of nearly east-west and south-north faults that formed at different times. The ore bodies are developed in the Paleozoic Naij Tal Group. The mine area reflects weak magnetic anomaly characteristics. The synthetic abnormalities have been determined by 1:50 000 stream sediment survey, which are dominated by gold and copper, with associated elements such as arsenic, cobalt and cobalt. The abnormals are well combined, and the three-level concentration is obvious. The remote sensing alteration information feature is primarily a hydroxyl alteration, and the iron dystaining anomaly occurs on the edge of the hydroxyl anomaly. Mineral deposits are closely related to the remoteness of geophysical features, and the comprehensive exploration results are very obvious. Through comprehensively studying the corresponding characteristics of this deposit, the references for the expansion of existing deposits or the discovery of new similar mineral deposits at their periphery can be provided in this paper.
