遥感技术在宗嘎顺地区1:50000矿产地质调查中的应用

Application of Remote Sensing Technology in Geological Survey of 1:50000 Mineral Production in Zonggashun Area

遥感技术应用于1:5万矿产地质调查中,进行了地质体、线性、环形构造的信息提取以及矿化蚀变信息的提取,结合地质、物化探综合工作成果,快速有效地指导了地面找矿工作,对合理圈定找矿靶区起到了重要作用,为编制成矿规律图和进行矿产预测提供了资料。本文介绍了内蒙古自治区阿拉善右旗宗嘎顺地区1:5万矿产地质调查项目遥感影像的处理与制作、工作区遥感地质特征,以及遥感提取羟基蚀变异常和铁染蚀变异常的过程,并结合地质特征和矿(化)点、矿床分布情况对提取的遥感蚀变异常进行了初步评价。

remote sensing technology is applied to the Geological Survey of 1:50000 mineral products,and the information extraction of geological bodies,linear structures and ring structures,and the information extraction of mineralization and alteration,combined with the results of geological and physical exploration,has quickly and effectively guided the prospecting work on the ground.It plays an important role in the rational determination of ore target areas,and provides information for the preparation of metallogenic regularity maps and mineral prediction.This paper introduces the processing and production of remote sensing images in the 1:50,000 mineral Geological Survey project in Zongashun area of Alxanyouqi,Inner Mongolia Autonomous Region,the remote sensing geological features of the working area,and the process of remote sensing extraction of hydroxyl etching anomalies and iron etching anomalies.Based on the geological characteristics and the distribution of ore(chemical)points and deposits,the remote sensing alteration anomaly extracted was evaluated.
