摘　　要：具有良好成矿地质环境的广西西大明山地区目前已探明10多种矿产,包括金、银、铅、锌等,目前已发现10多种矿产。其中,目前已探明矿点的有:大型银矿凤凰山、铅锌中型矿长屯、铅锌小型矿渌井。近年来,该区找矿成果最显著的是两个找矿项目,分别是大新县弄屯银铅锌多金属矿、富绥县罗维矿区铅锌矿。以已知的西大明山地质资料为背景,对在该矿区进行物探找矿的可行性进行了理论上的探究,从而构建了一个与实际地质结构相对应的数值模拟模型,从理论上探究了在该矿区开展物探找矿的可行性。针对代表性成矿地带,我们运用了高功率激发极化法进行实地测量,旨在界定矿体分布区域并探寻潜在的隐伏矿藏,从而为该矿区进一步的地质勘探活动及整体布局规划提供科学支撑。The West Daming area in the west of Guangxi has very favorable metallogenic geological conditions and rich mineral resources. Up to now, 10 kinds of minerals such as gold, silver, lead and zinc have been discovered. The proven deposits include Fenghuangshan large silver deposit, Changtun medium lead-zinc deposit and Lujing small lead-zinc deposit. In recent years, the most outstanding prospecting work in the mining area has been for two deposits: the Fusui Luowei silver-lead-zinc polymetallic deposit and the Nongtun lead-zinc deposit in Daxin County. Based on the known geological data of West Daming Mountain, this paper adopts the method of numerical simulation to build a model corresponding to the actual geological structure, and theoretically explores the feasibility of geophysical prospecting in this mining area. In view of the typical metallogenic area, the high-power IP method was used to carry out practical observation, which can be used to delineate the scope of ore veins and search for concealed deposits, and provide a basis for further geological prospecting and overall planning of the ore area.
