湖北随州—大悟地区遥感预测成矿研究

在矿产资源潜力评价工作中,利用遥感矿产预测五要素“线、带、环、色、块”及遥感近矿找矿信息,在遥感影像图上,寻找与金、铜、铅锌多金属矿化带和矿化蚀变的有关信息,发现并圈定成矿有利区段,为找矿勘探提供线索.通过在湖北北部新(城)-黄(陂)断裂带两侧,枣阳-随州-大悟-线的工作,利用遥感矿产预测五要素及其线、块双要素组合,线、环双要素构造组合,线、环、块三要素构造组合,线、环、色、块四要素构造组合,线、环、色、块及遥感近矿找矿信息五要素构造组合等多种组合形式,结合已有的矿化点及化探资料,圈定出4个本区遥感预测成矿的有利地段.建立了初步的遥感成矿预测模型,为今后开展此类工作提供了有益的尝试并积累了相关的经验.

Study of Metallogenic Prognosis Based on Remote Sensing of Suizhou-Dawu Area,Hubei Province

By mean of five features of RS and ore-prospecting information of RS in project of mineral resources potential evaluation,the author discovers the mineralized alteration information of gold,copper and zinc polymetallic mineralization zone in RS images,provides some clues to ore exploration.Along both sides of Xincheng-Huangpi Fault zone and Zaoyang-Suizhou-Dawu area in north of Hubei,the author delimitates four preferable ore-finding areas in light of five factors of RS mineral forecasting and various factor combinations such as twin factors of line and block or line and circle,three factors of line,circle and block,four factors of line,circle,color and block,and five factors of line,circle,color,block,as well as combining the given mineralization point and geochemical data.This paper builts a primary forecast model of Mineralization,provides a good attempt and accumulates relevant experience for the future related research.
