摘要
通过对西藏阿里狮泉河电站地区开展1∶5万水系沉积物测量,发现Cu元素异常强度较高,该区Cu地球化学异常主要与区内出露的地层(J_1b)巴秋岩组的变质基性火山岩和斑岩体有关,成矿元素组合为Co-Zn-Mn-Ti-Cu,与区内巴秋组(J_1b)火山岩展布几乎一致,说明本区的Cu的来源与巴秋组(J_1b)火山岩关系密切。工作区巴秋组(J_1b)火山岩分布广,结合地表已发现大量的热液活动产物,并伴有孔雀石的铜矿物,说明该区具有良好的找寻铜矿的潜力。
In our survey of 1：50 000 stream sediment of Shiquan river hydropower station in All region of Tibet, we have found that Cu element anomaly intensity is higher. The Cu geochemical anomaly is mainly with the autumn petrofabric of metamorphic basic volcanic rocks and porphyry. Ore - forming elements are in combination of Co - zinc- Mn- Ti, Cu, and the autumn group （J1b） in volcanic rock distribution unanimously. This paper also explains the source of the Cu of this area with the autumn group （J1b） closely related to volcanic rock. In workspace and autumn group （J1b） wide distribution of volcanic rocks, we have found that a large number of hydrothermal activity product and copper mineral malachite will be of a good potential area to be looked fnr in copper ore.
