基于GOCAD平台的西天山托克赛铅锌矿三维建模及深部靶区预测

3D Modeling and Deep Target Area Prediction of Toksai Pb-Zn Ore in West Tianshan Based on GOCAD Platform

托克赛铅锌矿是西天山别珍套山发现的中型SEDEX型铅锌矿,赋存于中元古界长城系一套白云岩地层中,且与闪长岩脉有强烈的空间的关系。通过对矿区地质工程及物探工程的综合整理,结合钻探及重、磁、电法等有效手段,对矿区开展了2500 m深度的综合探测,并利用GOCAD平台建立矿区0~2500 m的综合地质-物探三维模型,揭示深部矿体形态,预测深部找矿靶区,为今后深部找矿提供依据。

Toksai Pb-Zn ore is a medium-sized SEDEX-type Pb-Zn ore found in the Biezhengtao area of Western Tianshan,endowed in a set of dolomite stratigraphy of the Great Wall System in the Middle Metasedimentary Period,and has a strong spatial relationship with the Eclogite veins.Through the comprehensive collation of geological engineering and physical prospecting engineering of the mine area,combined with drilling and effective means such as heavy,magnetic and electrical methods,a comprehensive exploration of the mine area at a depth of 2500 m was carried out,and a comprehensive geological-physical prospecting 3D model of the mine area from 0~2500 m was established by using the GOCAD platform to reveal the morphology of the deep ore body and predict the deep search target area,which provides a basis for future deep search.
