摘要:
乱石山北一带位于阿木乌苏—鹰咀红山—老硐沟金、钨、锑成矿带（Ⅳ级）上。为快速准确开展矿产调查，通过1∶5万土壤地球化学测量，对土壤地球化学特征进行了初步分析，选择具有元素组合复杂、异常强度高、面积及规模较大等特征的综合异常,采用踏勘检查、1∶1万土壤地球化学测量、槽探工程等多种查证手段找寻矿化线索，在AP2土壤综合异常区发现Ag、Sb、Pb、Au、As富集强度高，在AP4土壤综合异常区寻找到1条银砷锑矿化体。结合成矿地质条件，认为该区找矿前景很好，是寻找中低温热液型金银砷锑多金属矿的有利地区。

Abstract:
The northern Luanshishan area is located on Amuwusu-Yingzuihongshan-Laodonggou gold-tungsten-antimony metallogenic belt(Grade Ⅳ).In order to carry out mineral survey quickly and accurately,the soil geochemical characteristics were preliminarily analyzed through 1:50 000 soil geochemical survey.The comprehensive anomaly area with complex element combination,high anomaly intensity,large area and large scale was selected to trace the mineralization clues by means of reconnaissance inspection,1:10 000 soil geochemical survey and trenching engineering,the enrichment intensity of Ag,Sb,Pb,Au and As was found high in AP2 soil comprehensive anomaly area,and a silver-arsenic-antimony mineralized body was found in AP4 soil comprehensive anomaly area.Based on the analysis of metallogenic geological conditions,it is considered that this area has good prospecting potentials,and is a favorable area for finding medium low temperature hydrothermal gold-silver-arsenic-antimony polymetallic deposits.
