摘　　要：双频激电法是一种装备轻便、效率较高的物探找矿方法,尤其对于高寒高海拔等通行困难、施工难度较大的地区具有重要意义。研究通过利用双频激电法在西藏某地区开展激电中梯测量,圈定激电异常4处,并进行了解释推断,有效指导了地面找矿工作,证明双频激电法在西藏寻找破碎蚀变型金矿效果较好。此外,通过与时间域激电法实测数据的对比研究,从方法原理和实际效果上说明了2种方法总体等效,但双频激电法在数据结果上找矿效果更明显。Dual-frequency IP method is a lightly equipped and efficient geophysical exploration in prospecting method,especially for alpine and high altitude and other difficult construction areas.This paper introduces the measurement of the electroelectric ladder in some area of Tibet,and it explains in deducing the ground prospecting work.Also,it proves that the two-frequency electroelectric method which will be of better effect in searching for broken corrosion gold mines in Tibet.In addition,the differences between two electrodynamics and the application effect are analyzed,but the dual-frequency IP method has a more obvious prospecting effect on the data results.
