摘要:

三山岛西岭金矿区位于渤海之滨,与北部海域金矿区相互连接,形成金资源量近千吨的巨型金矿床,矿床为地下与海底开采。区域内断裂发育,分布有NE向和NW向断裂,其中NE向断裂为控矿构造,而NW向断裂多具有不同程度的导水性,对矿床安全开采影响重大。基于矿区地质条件与地球物理特征,采用高精度磁测法和音频大地电磁(AMT)法在矿区东部进行了勘查试验,根据显示的磁性异常与电性异常,在平面上解译了NW向断裂(F-1、F-2)与NE向断裂(F-3、F-4),在L1剖面上解译了4条断裂,在L2剖面上解译了3条断裂。综合判断解译信息,NW向F-1断裂在平面与剖面上都反映良好。同时,与北部海域NW向构造研究资料进行对比分析,结果显示西岭矿区F-1推断断层与北部海域B-F4断层特征一致,吻合较好,推断西岭矿区NW向F-2断裂被F-3断裂错断。研究结果说明综合物探方法在该区域可行有效,为下一步钻孔验证NW向断裂存在,判断断裂富水及导水性质,以及未来矿床开发利用提供了地球物理依据。

Abstract:

The Xiling gold deposit of Sanshandao is located in the coast of Bohai sea.It connected with the north sea area gold deposit and they explore a huge gold deposit of nearly 1 000 t of gold resources.The deposit need to be mined underground and undersea.The faults in the region are well developed and distributed in NE and NW directions.The NE-trending faults are ore-controlling structures.The NW-trending faults in the region have different degrees of water conductivity,it has a great impact on the safe mining of the deposit,so it is very important to ascertain the spatial distribution of the NW trending faults.In view of geological conditions and geophysical characteristics of the area,the exploration test in the east of mining area by using high precision magnetic method and audio magnetotelluric (AMT) method to conducted.According to the magnetic anomalies and electrical anomalies,the NW-trending faults F-1,F-2 and NE-trending faults F-3 and F-4 were interpreted in plane,four faults were interpreted in L1 section and three faults were interpreted in L2 section.Comprehensive judgment interpretation information shows that the NW-trending F-1 fault responds well both in plane and profile.Comparing with the NW trending structure research data in the north sea area,the results show that F-1 fault of Xiling gold deposit was agree well with B-F4 fault of north sea features.It is inferred that the NW-trending F-2 fault in Xiling mining area is broken by the F-3 fault.The study shows that the comprehensive geophysical prospecting method in the area is feasible and effective.It provide a geophysical evidence for verifying the existence of the new fault structure and judging the water-rich and water-conducting properties of the fault for the next drilling,also provided the basis for future development and utilization of mineral deposits.
