摘　　要：西藏措美县卓木日金多金属矿是近年来通过区域地质调查工程新发现的金多金属矿点,矿区位于古堆-隆子断裂北侧,巴其-辛那断裂南西侧,措美-隆子锑金成矿带的西部。矿区出露的地层主要为上三叠统涅如组,矿化带受近北西向断裂构造控制。笔者通过分析矿区区域成矿地质背景、地质特征、1∶50000水系沉积物地球化学特征、1∶10000土壤地球化学特征、1∶10000物探中梯激电剖面特征和ETM+遥感影像特征,认为该区成矿地质条件较为有利。结合地质、化探、物探、遥感、探矿工程等资料综合研究,本文系统评价了卓木日金多金属矿的找矿潜力,以期对该地区进一步开展矿产勘查指明方向并提供可靠的参考依据。The Zhuomuri gold polymetallic deposit in Cuomei County,Tibet is a newly discovered gold polymetallic deposit through regional geological survey projects in recent years.The mining area is located on the north side of the Gudui-Longzi fault,southwest side of the Baqi-Sina fault and west of the Cuomei-Longzi antimony-gold metallogenic belt.The exposed strata mainly are the upper Triassic Nieru formation,and the mineralized belt is controlled by the near NW-trending fault structures.Based on analysis of the mineralization geological background,geological characteristics,1∶50,000 geochemical characteristics of stream sediments,1∶10,000 soil geochemical characteristics,1∶10000 geophysical prospecting IP profile characteristics and ETM+remote sensing image characteristics,the author thinks that the geological conditions in this area are more favorable for mineralization.Combining with comprehensive research on geology,geochemical prospecting,geophysical prospecting,remote sensing,prospecting projects and other data,the author systematically evaluated the prospecting potential of Zhuomuri gold polymetallic deposit,with a view to pointing out the direction and providing reliable reference for further mineral exploration in the area.
