摘要:
王花沅铜多金属矿处在于都矿集区北部,处于亚欧大陆板块与滨西太平洋板块消减带的内侧华厦板块中,经历了燕山期多起多阶段的岩浆活动。结合对王花沅铜多金属矿区的地层、构造和岩浆岩,以及矿体地质特征研究,总结出本区铜多金属矿主要产于王花沅花岗岩株与震旦系变质岩接融带附近的花岗岩内接触带中,矿体受北东向含矿石英脉及旁边的云英岩化带控制。根据矿物组合及矿(化)床矿物生成顺序分析,矿物生成主要有三个阶段:早期高中温阶段,晚期中低温阶段及次生阶段。类比区域铜多金属矿成矿规律,推测矿区西北部探矿权证范围证内、证外约1.5平方千米范围内具有较好成矿及找矿远景。

Abstract: Wanghuayuan copper polymetallic ore lies in the northern part of mining area, located in the Eurasian continental plate and the Pacific plate west coast mansion inside the reduction plate, and has experienced Yanshan multi-stage magmatic activity. With combination of the Strati- graphic, structural and magmatic rocks of Wanghuayuan copper polymetallic mining area, it summarizes what Copper polymetallic ore is mainly produced in the Wanghuayuan granite rock and near the contact zone of Sinian metamorphic granite, orebody is controlled by NE trending quartz veins and the near ore greisenized. According to mineral assemblages and ore bed mineral generation sequence analysis. There are three stages of mineral generation in the Wanghuayuan mining area: early stage of high and medium temperature, late stage at low tem- perature and the secondary phase. By comparing with the metallogenic regularity of copper polymetallic deposit in the area, it can be speculated that the scope of prospecting which is about 1.5 square kilometers around the mine lot has good mineralization and discovery prospects.
