摘要
通过地球化学元素在地质体中的分布规律,对研究区地层、岩浆岩及构造等进行合理解释推断以指导研究区的地质填图、找矿靶区优选工作;对黑龙江座虎滩-大卜场地区1:50 000土壤地球化学测量成果数据进行剩余异常分量R型因子分析并计算其因子得分,结合单元素异常特征,对各矿化因子所代表的信息进行整合,初步确定了本区岩浆岩、变质岩和沉积岩等地质体及构造断裂带位置,优选Au-Cu-Mo、Au-Cu、Cu综合找矿靶区五处。
In order to guide the geological mapping and prospecting target selection of the study area by rational interpretation of the strata,magmatic rocks and structures through the distribution rule of geochemical elements in the geological body,the R-factor of residual anomaly component of the soil geochemical survey data in Dapuchang area in scale of 1∶50000 were analyzed and the factor scores were calculated in this paper.Combining with single element anomaly,the paper integrated information of mineralization factor,and preliminarily delineated the fracture zone and geologic body of magmatic,metamorphic and sedimentary rock,selected five prospecting target areas of integrated Au-Cu-Mo,Au-Cu,Cu deposits.
