摘要

应用激电、自电、磁法及伽马能谱等多种物探技术手段,在天井山已知矿段进行有效性试验,研究各种物探异常与已知矿体矿化带的对应关系,优选出最佳有效物探找金方法组合,为本地区申请物探找金公益性立项提供技术依据。试验结果表明,激电、自电和伽马能谱异常在已知金矿体上均有明显反应,磁法效果不明显。因此,在该地区开展以激电方法为主,以自电、伽马能谱法为辅的物探普查工作,圈出隐伏矿体和深部盲矿体,扩大矿区资源量乃至实现皖南找金新突破,在技术层面是可行的。
        Many geophysical prospecting methods of IP, self-potential method, magnetic method and gamma ray spectrometry were employed to test their effectiveness in known ore blocks for studying the relationships of various geophysical anomalies with known ore bodies and mineralization belts, and thus singling out the best effective combination of geophysical gold-prospecting methods, providing technical basis for applying public geophysical prospecting project for gold. The results show that the anomalies of IP, self-potential method and gamma-ray spectra are obvious over known gold ore bodies, but magnetic method is not good. Therefore, it is feasible to carry out general survey dominated by IP, assisted by self-potential method and gamma ray spectrometry, to delineate concealed and deep blind ore bodies, increase mineral resources and even achieve a new breakthrough in gold prospecting in southern Anhui.
