青海查涌地区铜多金属矿地质地球化学特征及找矿前景

查涌地区铜多金属矿位于著名的青海三江北段铜多金属成矿带之通天河印支期铜、铅、锌成矿亚带内，大地构造位置为可可西里-金沙江晚古生代-早中生代缝合带，区内构造活动强烈，NW向断裂为重要的控矿构造。通过在该区系统开展1：5万水系沉积物测量和1：1万土壤测量工作，综合分析了地质地球化学特征，了解区内元素的分布规律和组合特征，固定成矿靶区，并结合地物手段，初步查明了矿体的形态、产状和规模。研究表明，该区具备良好的成矿地质条件，成矿潜力较大，具有较好的找矿前景。

Discussion on the Geological-Geochemical Characteristics and Prospecting of Copper-Polymetallic Deposit in Chayong Area,Qinghai Province

The copper-polymetallic deposit in Chayong area is located in the Tongtianhe copper,lead,zinc mineralization subzone in Indo-chinese epoch of the north of Sanjiang copper polymetallic ore belt,Qinghai Province,and the tectonic position is Kekexili-Jinshajiang suture belt whose age is the Late Paleozoic-Early Mesozoic.It is an important ore-controlling structure for the NW-trending faults in the intense tectonic activity area.Through systematically carrying out the 1：50 000 stream sediment survey and 1：10 000 soil survey works,the author comprehensive analyzed the geological and geochemical characteristics,comprehended the distribution of elements and the combined features, and delineated the mineralization target in the area.Finally, combined with the geophysical methods,the morphology,shape and size of the orebodies were initially identified.Studies have shown that the area has good geological conditions, mineralization potential, and good prospecting potential.
