摘要
安徽隆兴地区位于长江中下游铁、铜成矿带的中段北缘,张八岭成矿带北部南段。勘查区内找矿信息丰富,找矿线索较多,通过开展地质、物探和土壤地球化学测量,分析研究块状硫化物矿床及斑岩型铅锌矿床的成矿条件,并圈定勘查区内磁异常(编号C1、C2)及5处土壤地球化学元素异常,提出:①C1磁异常位置变细碧岩分布范围广、厚度较大、蚀变强烈、金属硫化物含量较多,是寻找铜金矿的有利靶区;②C2磁异常位置和求雨庙及其以东一带是勘查区寻找铅锌矿的重要靶区。
The Longxing area of Anhui Province is located in the northern margin of the middle section of the iron and copper metallogenic belt of the middle and lower reaches of the Yangtze River and in the southern section of the northern part of the Zhangbaling metallogenic belt.The information is rich and clues are many for mineral exploration in the area.After geological,geophysical and soil geochemical survey,analysis of metallogenic conditions of massive sulfide deposits and porphyry lead-zinc deposits,and delineation of magnetic anomalies(C1,C2)and five soil geochemical element anomalies in the area,conclusions are made as following:(1)the magnetic anomaly C1 where metamorphosed spilite is in wide distribution,large in thickness,strongly altered,and rich in metal sulfides is a favorable target for searching copper and gold deposit;(2)the magnetic anomaly C2,Qiuyumiao and the area to the east of it are important targets for prospecting lead-zinc deposits in the area.
