摘要
广西五圩锑多金属矿床位于江南古陆南缘、右江再生地槽北部边缘的丹池多金属成矿带南段,成矿地质条件优越,经区域重力异常、航磁异常及地质等综合资料分析,认为五圩矿区存在隐伏岩体。通过开展重力测量工作,以探索隐伏岩体的分布特征、起伏形态及埋深,并在矿区开展了可控源音频大地电磁(CSAMT)测深工作,以探索矿区深部锑多金属矿的空间展布特征。研究结果表明:五圩矿区向西约4 km处可能存在隐伏岩体,岩体顶界面埋深为2400~2800 m,在矿区北部圈定了6处直立或倾斜的带状低阻异常,推测其为矿化破碎带的总体反映。为勘查区的深部找矿工作指明了方向。
Wuxu antimony polymetallic deposit is located in the south of Danchi polymetallic metallogenic belt on the southern edge of Jiangnan Ancient Land and the northern edge of Youjiang Regenerated Trench.There is an excellent metallogenic condition in the region.According to the comprehensive study of the regional gravity anomaly,magnetic anomaly and geological data,there is a concealed rock mass in Wuxu mining area.The research has explored the distribution characteristics,undulating pattern and depth of concealed rock mass with the gravity survey.CSAMT sounding work is also carried out to explore the spatial distribution characteristics of deep antimony polymetallic mineralization body in the mining area.The research result shows that there might be the concealed rock mass about 4 km to the west of Wuxu mining area,and the rock mass top interface depth is 2400-2800 m.Six vertical or inclined low resistivity anomalies of strip-shape have been delineated in the northern part of the mining area,and all of the low resistivity anomalies might be caused by the ore-bearing fracture zone.It has pointed out the direction for deep prospecting work in the exploration area.
