摘要
多因素套合分析法是一种简便、快捷、有效的基于G IS的成矿预测方法.辽宁省地质矿产勘查局应用该方法在辽西杨家杖子多金属矿田外围进行成矿预测,在一个靶区内找到2个矿床.本文介绍了应用该方法在辽宁东部辽河群地层区进行铅锌矿成矿预测的工作过程和取得的成果.通过本次研究,作者认为辽河群地层区在铅锌矿找矿方面仍有较大的潜力,推测在5个找矿靶区中有可能找到多处小到中型铅锌矿床.
The muhifactor overlap analysis, based on GIS （ hic Information System）, is a new method of metallogenic prognosis, by which two nonferrous metallic deposits have been found within one target in Western Liaoning Province. In this paper, the authors introduce the result of the method applying in lead-zinc ore metallogenic prognosis in Liaohe group in Eastern Liaoning. The Liaohe group covers 7% land of the province, but about 43% of lead-zinc deposits occur in the stratum. Therefore Liaohe group has a great potential for lead-zinc ore prospecting. With the multifactor overlap analysis, 5 prospect areas and 11 targets are determined in Liaohe group. And more small or medium sized deposits are expected.
