%X 为优化矿产资源找矿靶区，于辽宁省岫岩县兴隆沟地区开展了1:1万土壤地球化学测量工作。通过多元统计分析方法查明：研究区内Pb、Ag、As三种元素成矿潜力最大，As、Bi、Cu、Pb、Sb、Zn元素与Ag元素相关性较好，是Ag矿化体的重要找矿标志；结合该区地质特征圈定了单元素异常26处、组合异常3处，各异常套合较好；经工程验证，确定研究区中部硅化蚀变带为矿致异常，该蚀变带主要受盖县组地层与花岗岩、花岗闪长岩岩体接触带控制；结合区内地质特征确定2处预测区为寻找Ag等多金属矿产优选靶区。土壤地球化学测量方法在该地区应用的有效性同时也为相同地球化学景观区的找矿工作提供了可以借鉴的方法与思路。<br />
In order to optimize the prospecting target area of mineral resources, 1:10,000 soil geochemical survey was carried out in Xinglonggou area, Xiuyan County, Liaoning Province. Through the method of multivariate statistical analysis, it is found out that Pb, Ag and As have the greatest metallogenic potential in the study area, and As, Bi, Cu, Pb, Sb and Zn elements have a good correlation with Ag elements, which are important prospecting indicators of Ag mineralized bodies; combined with the geological characteristics of this area, 26 single element anomalies and 3 assemblage anomalies are delineated, and each anomaly combines well. Through engineering verification, it is determined that the silicified alteration zone in the central part of the study area is an ore-induced anomaly, which is mainly controlled by the contact zone between Gaixian formation strata and granite and granodiorite; combined with the geological characteristics of the area, two prediction areas are determined as the preferred targets for searching for Ag and other polymetallic minerals. The effectiveness of the application of soil geochemical survey in this area also provides a reference method and idea for ore prospecting in the same geochemical landscape area.
