激发极化法在广西陆尾金矿中的应用研究
|
摘要
广西陆川矿化集中地区内断裂构造复杂,岩浆活动强烈,水系也较为发育,前人在研究区已开展过一系列地质及地球物理勘查工作。针对本区多金属矿与围岩蚀变关系比较密切的特点,采用了电法分支方法-激发极化法进行勘查。利用激电中梯扫面和测深的方法在研究区中圈定了成矿优势区,再结合测区的地质情况分析异常情况,通过激电测深2.5维反演的方法推断出隐伏矿体的深度,最终以测区10线为实例来进行异常解释推断并且设计钻孔位置,达到预测金成矿远景区的目的。
Induced the fault structure in Luchuan mineralized area of Guangxi is complex, the magmatic activity is intense,and the water system is more developed. A series of geological and geophysical prospecting work has been carried out by predecessors in the study area. In view of the close relationship between the alteration of the polymetallic deposit and the surrounding rock in this area, the method of electrical method branching-excitation polarization is used for prospecting.Excavation dominant zone was delineated in the study area by means of sweeping and sounding of the intermediate ladder.Combined with the geology of the survey area, anomalous conditions were analyzed. The depth of the body, and finally the abnormal interpretation of the 10-zone survey line to infer and design the drilling location to achieve the purpose of predicting the gold prospecting area.
