摘要
Abstract
Located in the north-central part of Laos, the work area is covered by rainforest and adjacent to the intersection between NW-trending Truong Son magma-tectonic belt and NE-trending Louangphabang magma-tectonic belt. In order to survey the copper poly-metallic resources of this work area, the authors employed high-precision geomagnetic method and IP intermediate gradient respectively, and the results show that most geophysical anomalies correspond to the distribution of skarn mineralized bodies in the contact zone between granite and carbonate rock. A comparison of high-precision geomagnetic method with IP intermediate gradient shows that the exploration effect of high-precision geomagnetic method with lower cost and simple operation is better than that of IP intermediate gradient in rainforest landscape areas.关键词
