Abstract

The Qiushuwan Cu-Mo deposit, situated in the East Qinling molybdenum belt, is a notable mining site renowned for its considerable quantities of medium-sized molybdenum. The goal of this study is to improve comprehension and identify additional mineral resources by conducting a thorough examination of the mine using the spread spectrum-induced polarization (SSIP) technique. Gathering SSIP data, conducting geological investigations, and examining the electrical characteristics of rock and mineral samples along Profile-80 led to significant discoveries. The investigation identified two significant ore bodies with high conductivity: C2, linked to granite porphyry and molybdenum veins, and C4, associated with a skarn deposit containing a concentrated amount of copper ore. This study used resistivity models created from SSIP data to find out how conductivity changed in different parts of the research area. Additional drill verifications validated these findings, indicating the presence of potential mineral resources. The petrographic analysis of core samples showed that minerals like pyrite, molybdenite, chalcopyrite, epidote, calcite, and garnet were present. Notably, the samples frequently contained both pyrite and molybdenite together. Sample 04-2 contained substantial quantities of molybdenite and pyrite; Sample 05-1 had occasional pyrite; and Sample 07-4 included both pyrite and chalcopyrite. These findings offer useful insights for evaluating the magnitude and economic feasibility of the mineral deposits; however, additional investigation is required to completely comprehend the scope of the resources. The integration of borehole data and the alignment of geological sections with inversion models confirmed the validity of the conclusions. The core samples that were retrieved show a lot of different minerals, including valuable ores and minerals that have been changed. Pyrite and molybdenite are always found together. These findings establish a solid basis for further investigation and the sustainable management of resources. This study contributes to the understanding of the Qiushuwan Cu-Mo deposit and advances exploration techniques using the spread spectrum-induced polarization (SSIP) method. It provides useful information for geologists, mining professionals, and stakeholders involved in resource usage.

中国河南省南部秋水湾铜钼矿床的扩频诱导极化(SSIP)勘探
位于东秦岭钼矿带的秋水湾铜钼矿床是一个著名的矿区,以其大量的中型钼而闻名。本研究的目标是利用扩频诱导极化(SSIP)技术对该矿区进行彻底检查,从而提高对该矿区的了解,并确定更多的矿产资源。通过收集 SSIP 数据、开展地质调查以及沿剖面-80 检查岩石和矿物样本的电特性,我们发现了重大发现。调查发现了两个具有高导电性的重要矿体:C2 与花岗岩斑岩和钼矿脉有关,C4 与含有大量铜矿石的矽卡岩矿床有关。这项研究利用 SSIP 数据创建的电阻率模型来了解研究区域不同部分的导电率变化情况。额外的钻探验证了这些发现,表明了潜在矿产资源的存在。岩芯样本的岩相分析表明,存在黄铁矿、辉钼矿、黄铜矿、闪锌矿、方解石和石榴石等矿物。值得注意的是,样本中经常同时含有黄铁矿和辉钼矿。04-2 号样品中含有大量辉钼矿和黄铁矿;05-1 号样品中偶尔含有黄铁矿;07-4 号样品中同时含有黄铁矿和黄铜矿。这些发现为评估矿床的规模和经济可行性提供了有益的启示;然而,要完全了解资源的范围,还需要进行更多的调查。钻孔数据的整合以及地质剖面与反演模型的吻合证实了结论的正确性。取回的岩心样本显示出许多不同的矿物,包括有价值的矿石和已经发生变化的矿物。黄铁矿和辉钼矿总是一起被发现。这些发现为进一步调查和资源的可持续管理奠定了坚实的基础。这项研究有助于人们了解秋水湾铜钼矿床,并推进了使用扩频诱导极化(SSIP)方法的勘探技术。它为地质学家、采矿专业人员和资源利用相关方提供了有用的信息。
