安徽省庐枞地区成矿规律及找矿方向

Mineralization regularity and exploration direction in Luzhong area,Anhui

庐枞地区是长江中下游成矿带的一个重要矿集区,已探明的有罗河、龙桥、大鲍庄大型铁矿,大鲍庄、何家小岭大型硫铁矿,沙溪、井边中型铜矿,岳山中型铅锌银矿等。本文根据区内不同类型矿床的成矿地质条件及矿床的空间分布特征,总结庐枞地区区域成矿规律。结合以往地质资料和近年来地质找矿成果的综合分析,提出庐枞地区具有较大远景的找矿靶区有:(1)沙溪铜(金)找矿靶区;(2)清水塘—岳山铁、铅锌找矿靶区;(3)井边—巴家滩铜矿找矿靶区。

Luzong volcanic basin is one of the most important mineralization enrichment regions with large or middle scale deposits of iron,sulphur,and copper,lead and zinc ,such as the famous Luohe iron deposit, Longqiao iron deposit and Dabaozhuang iron deposit, Dabaozhuang and Hejiaxiaoling pyrite deposits,Shaxi and Jingbian middle scale copper deposits,and Yueshan middle scale lead,zinc and silver deposit. According to the geological setting of mineralization of different types of deposits and characters of space distributions of deposits, the regional mineralization regularity for Luzong area is summarized. Considering the former geological data as well as recently ore-prospecting achievement, the relatively perspective ore-prospecting targets are proposed as follows： 1 ）Shaxi copper （gold） prospecting target ,2） Qingshuitang-Yueshan iron, lead zinc prospecting target, 3 ） Jingbian-Bajiatan copper prospecting target.
