| 中文摘要: |
| 驼路沟钴矿床是近年来在东昆仑南带中新发现的独立钴矿床。通过对矿床地质及地球化学特征研究表明,驼路沟钴矿床的形成主要与热水沉积作用有关;成矿后,在后期的碰撞造山过程中,由于SN向挤压,矿床遭受到强烈变形改造作用,导致含矿岩系发生了强烈的构造置换改造作用,矿体显示出"似层非层,似脉非脉"的特点;而且更晚期的断裂构造活动造成矿带差异性抬升及剥蚀。因此认为该矿床为热水喷流沉积 构造改造型矿床。依据矿床的成矿规律及控矿条件,提出了驼路沟钴矿床进一步的找矿方向。 |
| 英文摘要: |
| Tuolugou Co deposit is a newly discovered independent Co deposit in the southern margin of Eastern Kunlun orogen. Based on analyzing ore geology and geochemistry characters, the formation of Co deposit mainly related to hot water sedimentation. After the deposits were formed, during the process of collision orogenesis in late stage, owing to south-north oriented compression result, the deposit underwent intensively deformation and reform. As a result, ore-bearing rock series were exposed to intensive structural replacement , and ore bodies were characteristic of "stratiform but not bed, veinlike but not vein". Furthermore, later phase structural activity made the mineralization belt diverse uplift and denudation. It is affirmed that the deposit is a kind of exhalative sedimentary hydrothermal and structural alteration ore deposit. According to metallogenic regularities and ore-controlling condition, the exploring orientation of Co-Au deposits in Tuolugou have been proposed. |
