摘要
研究区位于承德乌龙沟—上黄旗深断裂带的东支棋盘山北东向深断裂上,是银铅锌多金属矿的找矿远景区。本文结合区域地质、地球物理及地球化学特征,在其所判定的成矿远景区,开展了以激电中梯和可控源音频大地电磁测深法为组合方式的综合物探找矿实践。利用激电中梯扫面方式对地球化学异常带进行查证,圈定出矿体和矿化体异常,而后,利用可控源音频大地电磁测深法进行异常主剖面测量,以查明异常体的地下空间展布,指导钻探验证工作的布设。实践表明:该找矿模型效果显著、经济高效,对同类地质成矿地区的隐伏多金属矿勘探工作具有一定的参考价值。
This research area is in deep fracture that directs to Northern--east of East branch board Qipan Mountain which in Chengde Wu Longgou - Shang Huangqi deep fracture zone, is the silver lead zinc polymetallic ore deposit. This paper, combined with regional geological, geophysical and geochemical characteristics, carried out integrated geophysical prospecting practice that is the combination method of IP with central gradient array and CSAMT in the determined mineralization vision zone. The use of IP in scanning the surface mode verified geochemical anomaly zone to delimit anomaly of ore body and mineralized body. Then, making use of CSAMT for the main profiling measuring to identify spatial distribution of underground of anomalies and guide drilling verification＇s layout. Practice shows that., the exploration model results are obvious and effective, which will provide a basis for the areas of similar geology concealed multi--metal ore mining exploration.
