| [摘要]阳春盆地是粤西地区主要的铜铅锌矿等多金属矿的矿集区,已知的铜铅锌锡银金矿床类
型种类较多,结合盆地强烈的构造运动、岩浆活动、变质作用,说明阳春盆地具有寻找铜铅锌锡银金的找
矿潜力。具有进一步寻找铜矿的潜力区域主要是断裂交汇部位的阳春黄坡一带的Cu 异常区及那软地
区,以夕卡岩型为主;铅锌矿床主要产于泥盆系地层中,具有铅锌找矿潜力的重点应放在盆地边缘;盆地
及周边的银异常环状连续分布,异常强度高,据了解该区域以往未开展过银矿调查评价工作,具有较大
的找矿潜力。本文通过对研究区地层、构造、岩浆岩与成矿关系总结的基础上,探索该区成矿规律,初步
建立了找矿模型,综合前人的研究成果,在阳春盆地及周边筛选了捞虾田-山塘角铜(钼)铅锌(银)找矿
潜力区、铁屎迳铅锌(铜银)找矿潜力区、高基-荔枝山铅锌(铜银) 找矿潜力区、大坑铜找矿潜力区等四
个有较大潜力的找矿区域,为该区进一步开展地质找矿工作明确了方向。 |

| Abstract:The Yangchun basin in western Guangdong Province hosts copper, lead and zinc polymetallic deposits of a variety types. Analysis of inten鄄
sive tectonic movements, magma activity and metamorphism suggests that there are potential polymetallic deposits in this basis. Specifically, the potential
skarn copper deposit is located in the Naruan area where faults intersect; lead-zinc deposit may occur at the edge of the basin; and silver would be found
in/ around the basin where exist anormalies of Ag in circular distribution with big amplitudes. Based on summarizing the relationship of strata, structure,
magmatites and mineralization, this work attempts to explore the metallogenic rules in this area and establish an ore-search model. In combination with
previous work, four potential deposits are determined, which are the Laoxiatian-Shantangjiao copper-(molybdenite) -lead-zinc-(silver), Tieshijing
lead-zinc-(copper-silver), Gaoji-Lizhishan lead-zinc-(copper-silver) and Dakeng copper areas, which can illuminate the further prospecting direc鄄
tion in the Yangchun Basin. |
