广东省阳山县石寨铅锌多金属矿地质特征

         

摘要

阳山县石寨矿区隶属南岭钨锡多金属成矿带,属矽卡岩型铅锌多金属矿,是武警黄金九支队首次针对此类型矿床进行勘查。矿区内花岗岩体广泛与石炭系地层接触,接触带长度延伸较长,具有较好的成矿条件。已发现的矽卡岩带,受接触带构造影响,在走向与倾向上整体呈“S”型舒缓波状,铅锌矿体主要赋存于矽卡岩带中。通过物化探基础性工作,并利用钻探及槽探工程进行查证,物化探异常与已发现矿脉吻合度较高,且深部呈现铅锌多金属元素富集增高的趋势,显示了较好的找矿前景。通过对区内多金属矿床地质特征、成矿规律分析与找矿前景分析总结,为在该区深部进一步开展找矿勘探,扩大其远景规模提供了明确方向和详实的地质资料。%Shizhai mining area of Yangshan is a skarn-type Pb-Zn polymetallic deposit which is located in Nan-ling W-Sn polymetallic metallogenic belt.It’s the first time that No.9 Gold Geological Team of CAPF has conducted exploration works on this type of deposits.The metallogenic conditions are favorable because the contact between granite body and Carboniferous stratum is extensive and long in length in this mining area. Under the influence of the structure of contact zone,the discovered skarn belt shows S-shaped gentle wave-forms in strike and trend.The Pb-Zn orebodies mainly occur in the skarn belt.Through geophysical and geo-chemical exploration as well as drilling and trenching works ,it is verified that the geophysical and geoche-mical anomalies match very well with the discovered ore veins,and elements like Pb and Zn are enriched and increased in the deeper part.It is indicated that the mining area has great prospecting potential.This paper analyzed and summarized the geological characteristics,metallogenic regularity and prospecting potential of the poly-metallic deposits in the area,and provided a clear direction and full and accurate geological data for further exploration works in the deep part of this area and expansion of prospecting potential area in the future.
