中文摘要:
      虎头崖矿床位于青海省祁漫塔格地区东部,区内矿产丰富、矿种多样、组合复杂,找矿潜力巨大。本研究针对该区域高寒山区的特殊地质条件,聚焦解决隐伏有色金属矿产勘探难题,以期高效、准确地识别并定位高寒环境下隐伏矿体的空间分布。设计并实施了基于物化探综合找矿方法的试验研究,采用双频激电扫面技术,结合高频大地电磁测深方法,以获取深部地质结构的电性特征,有效区分矿化与非矿化异常。同时,结合原生晕和次生晕地球化学找矿手段,通过多元素地球化学异常分析,进一步预测矿化作用的空间分布。上述综合探测技术的应用,在青海虎头崖地区取得了较好的试验效果,圈定了潜在矿化带,探索了适用于高寒山区的隐伏有色金属矿产的找矿技术方法,该工作方法可为周边勘查区及高寒山区隐伏地层找矿工作提供借鉴。
英文摘要:
      The Hutouya deposit is located in the eastern part of the Qimantage region, Qinghai Province, which is rich in diverse mineral resources with complex combinations, harboring tremendous potential for prospecting. This study, tailored to the unique geological conditions of alpine regions in this area, focuses on resolving the challenges associated with the exploration of concealed non-ferrous metal deposits, aiming to efficiently and accurately identify and locate the spatial distribution of concealed ore bodies in alpine environments. A pilot study based on a comprehensive geophysical and geochemical prospecting methodology was designed and implemented. The study utilized dual-frequency induced polarization (IP) scanning technology, coupled with high-frequency magnetotelluric sounding methods, to acquire the electrical characteristics of deep geological structures, effectively distinguishing mineralization anomalies from non-mineralization anomalies. Additionally, geochemical prospecting techniques involving primary and secondary halos were incorporated, with multi-element geochemical anomaly analysis further predicting the spatial distribution of mineralization. The application of these comprehensive exploration techniques achieved promising results in the Hutouya area of Qinghai, delineating potential mineralization zones and exploring effective prospecting techniques tailored for concealed non-ferrous metal deposits in alpine regions. The methodologies employed in this study can serve as a valuable reference for prospecting in surrounding exploration areas and concealed strata in alpine regions.
