| 摘 要： | 庐江-枞阳(庐枞)火山岩矿集区南部作为寻找沉积-叠加改造型铁铜矿的有利地区一直没有较大找矿突破,该区近几年勘查取得了一定地质找矿进展。本文主要在野外地质调查的基础上,对庐江-枞阳火山岩矿集区南部城山地区地质条件进行总结分析,重新认识了区内地层的含矿性以及构造特征,发现了大量矿化线索。在研究区内发现了4条与岩浆热液有关的铜铁铅锌矿化带,而且具有一定规律,空间上平面均为北东东、东西向,垂向上从深到浅具有从钼到铜铅锌矿化分带。成矿时间从126.5Ma开始。研究区内大规模磁铁矿化以及铜铅锌矿化的存在,表明深部具有较好找矿潜力。

| Abstract: | There has not been a big breakthrough in mineral exploration in the southern part of the Lujiang-Zongyang volcanic ore concentration region, though which is thought to be an area favorable to sedimentarysuperimposed reworking iron-copper ore deposit. Some progress was made in recent years. On the basis field geological survey, this paper summarized geological conditions in the Chengshan area in the southern part,renewed understanding of ore-bearing potential in the strata and of structural features in the area, then found a great deal of mineralization traces, including 4 magmatic hydrothermal fluid-related copper-iron-lead-zinc mineralization belts occurring in a regular pattern, i.e., all trending NEE or EW in plane, and vertically zoning from deep to shallow as molybdenum to copper, lead and zinc mineralization and starting from 126.5Ma. Wide expanse of magnetite and Cu-Pb-Zn mineralization suggests good prospect for mineral exploration in the depth. |
