摘要: 应用深穿透集成技术，在常规勘查方法难以奏效的高原寒冷区开展了隐伏金矿预测研究。选定的技术手段是可控源大地地磁法、地球电化学法与吸附相态Hg法组合。通过对已知区的示范研究，验证了该方法组合的有效性，并总结了适合高原寒冷景观条件下的综合找矿模式。利用建立的综合找矿模式, 在忠曲矿区外围开展了预测隐伏金矿的工作，圈定了综合找矿靶区8处。

Abstract: In this paper，the integrated technology of deep penetration to forecast hidden gold ore deposits in the plateau cold area, where the conventional prospecting methods seem inefficient. This coalescence technology includes Controlled Source Audio-frequency Magnetotelluric (SCAMT), geoelectric chemical extraction method （CHIM） and the method of measuring the adsorbed mercury in the surface soil. Through the feasible research on the existing ore by such technological combination, the authors found that it was effective in detecting the hidden ore deposits, and hence the prospecting model for this special region was established. With this integrated method, the authors delineated eight exploration targets in the periphery of the Zhongqu orefield.
