金寨县汤汇地区土壤地球化学特征及找矿意义

Pedogeochemistry and Its Prospecting Significance in the Tanghui Region,Jinzhai,Anhui

金寨县汤汇地区位于北淮阳构造带,通过在该地区开展1∶10000土壤地球化学测量,研究区内不同元素的地球化学异常特征。根据不同元素的地球化学性质利用因子分析确定元素在空间上的异常组合。根据元素组合中不同元素之间的异常在空间上出现的叠加现象,圈定出以Au、Ag为主的AP-1综合异常带及以Cu、Au为主的AP-3综合异常带。结合研究区地层、岩浆岩、构造等地质特征,评价重点综合异常的找矿前景。

The Tanghui region,Jinzhai County lies in the north Huaiyang structure zone.Comprehensive geochemical anomalous zone AP-1 dominated by Au-Ag geochemical anomalies and comprehensive geochemical anomalous Zone AP-3 dominated by Cu-Ag geochemical anomalies are delineated in the Tanghui region.The prospecting potential of the two comprehensive geochemical anomalous zones are evaluated based on stratigraphy,structure and magmatic rock in the studied region.
