阳春市麻料铅锌多金属矿地质特征与成矿规律
|
摘要
阳春盆地是广东省最重要的成矿带之一,麻料矿区位于阳春盆地南缘,是新近发现的一处铅锌多金属矿床,矿脉主要受NWW—NW向和近SN向断裂构造控制,赋矿围岩为中粗粒黑云母二长花岗岩。详细分析了麻料铅锌金属矿地质特征,并对其成矿规律进行了探讨。研究表明:矿床成因类型为中低温热液充填交代型矿床,矿区具有明显的区位优势和良好的成矿地质条件,找矿潜力较大。
Yangchun Basin is one of the most important metallogenic belts in Guangdong Province.Maliao deposit is located in the southern border of Yangchun Basin,which is a newly discovered Pb-Zn polymetallic deposit.The ore vein is mainly controlled by the NWW-NW direction and nearly North-Southern faulted structure,the ore-hosting rock is composed of medium-coarse biotite adamellite.The geological characteristics of Maliao Pb-Zn polymetallic deposit is discussed,and its metallogenic regularity is studied.The results show that genesis type of the deposit is probably belongs to medium-low temperature hydrothermal filling metasomatic type deposit,the regional advantages and metallogenic geological conditions of the mining area are both good,the prospecting potential of the area is huge.
