GIS在鄂东地区第二轮铁矿找矿中的应用

APPLICATION OF GIS TO THE 2^(nd) ROUND OF IRON ORE EXPLORATION IN THE EAST HUBEI PROVINCE

通过地理信息系统(GIS)可以对与成矿有关的各种空间信息进行分析,确定成矿的有利靶区。利用GIS(MAPGIS)功能对鄂东地区大量的铁矿地质信息进行二次开发,验证铁矿的成矿规律和找矿标志,确定了铁矿成矿与地层、岩浆岩、构造和磁异常有着紧密的联系,并据此对鄂东地区隐伏铁矿床进行预测,圈定了4处可供第二轮找铁矿的有利目标靶区。

Geographical information system （GIS） has been widely used in analysis of various spatial data.related to ore and determination of ore-searching targets. We take the advantage of GIS（MAPGIS）functions to make secondary development of large volume of iron ore deposit-related geological data from the east Hubei province and verify metallogenic pattern and ore-searching marks of the iron ore deposits and close relation of strata, magmatic rocks, structures and magnetic anomlies to iron ore is ascertained. Based on the results blind iron ore deposits in the east Hubei province are predicted and four targets are lineated for the second round of iron ore-searching in the area.
