| 中文摘要: |
| 针对新疆路北铜镍矿区超基性岩赋矿体受冲积物覆盖、地表露头稀少，以及传统激电方法因凝灰岩裂隙面黄铁矿/含炭物质干扰导致深部异常分辨率不足的问题，旨在探索三维激电技术对深部含矿基性-超基性岩体的空间定位能力。本文采用震旦三维激电观测系统，构建矿区电阻率与极化率的三维空间模型，结合重、磁数据开展综合解译，系统分析覆盖区深部岩体展布特征。研究实现了矿区 1000 m深度的有效探测，并建立了铜镍矿三维激电找矿标志，综合圈定 IP1、IP6两处高精度找矿靶区，为钻探提供了科学依据。震旦三维激电系统兼具大探测深度与高分辨率优势，有效突破了传统方法在深部隐伏矿体识别中的局限性，证实其为覆盖区铜镍矿勘查的高效技术手段。对同类型矿床深部找矿具有重要示范意义。 |
| 英文摘要: |
| To address the challenges in the Lubei copper-nickel mining area of Xinjiang—where ore-bearingultrabasic rocks are covered by alluvial deposits, surface outcrops are scarce, and traditional induced polarization(IP) methods suffer from poor resolution at depth due to interference from pyrite or carbonaceous materials alongfractures within tuff—this study aims to evaluate the spatial positioning capability of three-dimensional (3D) IP technology for deep-seated mineralized mafic–ultramafic intrusions. Using the Zhendan 3D IP observation system,we constructed a 3D resistivity and chargeability model of the mining areas. By integrating gravity and magneticdata, we conducted a comprehensive interpretation to systematically analyze the distribution patterns of deep intru.sive bodies beneath the cover. Our research achieved effective detection to depths of up to 1000 meters and estab.lished 3D IP indicators for copper-nickel mineralization, delineated two high-precision exploration targets (IP1 andIP6), thereby providing a scientific basis for drilling. The Zhendan 3D IP system combines deep penetration andhigh resolution, effectively overcoming the limitations of traditional methods in identifying concealed deep ore bod.ies, and has proven to be an efficient exploration technique for copper-nickel deposits in covered regions. Thisstudy offers important implications for deep exploration in similar types of ore deposits. |
