中文摘要：

商旭造山型金矿床位于班公湖—怒江成矿带中部,矿体受NWW向断裂构造控制,呈脉状、透镜状产于木噶岗日群中-下侏罗统木嘎岗日群浅变质复理石中。为探讨商旭金矿外围的找矿潜力,本文利用多元统计方法,对商旭-达则地区1∶5万水系沉积物地球化学测量数据进行了分析,提取出3个具有代表性的因子,绘制出地球化学分区图及因子得分等值线图,并讨论了各分区与其地质背景的对应关系。结合研究区地质特征认为,Au-As-Sb元素组合为商旭-达则地区的最佳地球化学标志元素,外围找矿工作的重点应放在研究区东部的作布地区以及研究区西部的达则地区,同时齐隆、陆任、热木隆等地区也具有较好的找矿前景。

英文摘要：

The Shangxu orogenic gold deposit is located in the middle segment of Bangonghu-Nujiang polymetallic metallogenic belt in Tibet. Ore bodies occur as veins and lens controlled by the NWW fractures, lying in the Middle-Lower Jurassic Mugagangri Group which is mainly composed of metamorphic flysh. In order to investigation the prospecting potential in the surrounding of shangxu gold deposit, This paper analyzed the 1∶50000 geochemiscal data of the stream sediment in the Shangxu-Daze area by the multivariate statistics analysis method. Three representative factors were extracted from the data, and a geochemical subdivision map and a factor score map were drew. Combined with field geological work, the authors hold that Au-As-Sb is the optimum element combination for prospecting prediction. In future work in the surrounding of shangxu gold deposit, the Zuobu area and Daze area should be regarded as the preferred exploration areas. Meanwhile, the area of Qilong area, Luren area, and Remulong area also have good potential in the exploration of the gold deposit.
