摘要:
针对东昆仑造山带隐伏矿体勘查的局限性，以卡而却卡铜多金属矿床为例，通过区域地质调查、地球化学异常识别及综合找矿技术方法的应用，系统分析了矿床地质特征、成矿机制，建立了综合找矿模型。研究结果表明，该矿床的形成与晚三叠世—早侏罗世中酸性岩浆侵入活动密切相关，岩体与围岩接触带是主要控矿构造；综合找矿技术的应用显著提高了勘查成功率，取得了找矿突破，验证了综合找矿模型在东昆仑造山带寻找斑岩型铜矿的适用性，并揭示了区域岩浆活动、构造演化与成矿作用的内在联系。该研究不仅为东昆仑造山带矿产勘查提供了科学依据和实践指导，还丰富了区域成矿理论，对隐伏矿体勘查具有重要的学术价值和实际应用潜力。

Abstract:
To address the limitations in exploring concealed orebodies within the East Kunlun Orogenic Belt, acase study of the Ka’erqueka Cu polymetallic deposit was conducted. Through regional geological surveys, identification ofgeochemical anomalies, and the application of integrated prospecting technologies, the geological characteristics andmetallogenic mechanisms of the deposit were systematically analyzed, leading to the establishment of an integratedprospecting model. Results indicate that the formation of the deposit is closely related to Late Triassic-Early Jurassicintermediate-acid magmatic intrusions, with the rock mass-surrounding rock contact zone serving as the primaryore⁃controlling structure. The application of integrated prospecting technologies significantly improves explorationefficiency, achieves breakthroughs in mineral discovery, and validates the suitability of the integrated prospectingmodel for porphyry⁃type copper deposits in the East Kunlun Orogenic Belt. This study also reveals the intrinsic relation⁃ships among regional magmatic activities, tectonic evolution, and mineralization. The findings not only provide a scien⁃tific basis and practical guidance for mineral exploration in the East Kunlun Orogenic Belt but also enrich regionalmetallogenic theory, demonstrating significant academic value and potential for practical application in exploring con⁃cealed orebodies.
