物探方法在贵州东部某铅锌矿区勘查中的应用

The Application of Geophysical Prospecting Methods in Lead-Zinc Mine Exploration of Eastern Guizhou

贵州东部某矿区位于贵州省凯里—都匀地区铅锌矿整装勘查区内,是湘黔桂地区中低温热液矿床成矿的有利部位,以往的物化探工作程度相对较低,找矿主要依靠地质工作,找矿成果主要集中在浅表200m以内,中深部找矿未取得较大突破。以整装勘查项目为依托,主要研究了物探激发极化法和大地电磁法在攻深找盲、划分地层构造、圈定找矿靶区中的应用,物探成果和地质成果取得了较好的对应,总结了区内的地球物理特征,并将此特征应用于相邻区块,取得了不错的找矿效果。

The mining area of eastern Guizhou province is located in Kaili-Duyun region of lead-zinc mine monoblock exploration areas,is the advantageous position of medium to low temperature fluid metallogenic in Hunan,Guizhou and Guangxi.The previous geophysical and geochemical exploration work level is relatively low,prospecting relies mainly on the geological work,so the ore-prospecting achievements mainly concentrated in the superficial within 200 meters,and the deep prospecting has not been a breakthrough.The article based on monoblock exploration project,mainly studying the application of induced polarization method and audio-frequency magnetotelluric for finding deep blind ore,dividing stratum structure,and outlining the prospecting target.Geophysical exploration results with good correspondence to the geological results.Summarized the geophysical characteristics of area,and applying the characteristics to adjacent blocks,achieving good ore-prospecting results.
