河南土地庙沟——银洞山铅多金属矿多元综合信息成矿预测

土地庙沟—银洞山地区铅多金属矿床位于华北陆块南缘与秦岭造山带东段的接壤部位,在依据前人地质成果资料的基础上,通过野外数据收集,依据关键控矿因素、成矿模式及成矿规律,根据数学地质学理论,利用智能化平台,结合已获得的地、物、化、遥等数据对找矿信息提取与分析,获得具有预测意义的找矿标志信息,利用层次分析法确定找矿标志的权重,对成矿模式和找矿标志应用多元信息模糊综合评判法进行综合集成和对比分析,圈定了4个找矿靶区,为后续的找矿工作部署提供理论支撑与参考,为该区的成矿预测研究提供了技术支持和科学依据。

Multiple information prospecting prediction for lead polymetallic deposit in Tudimiaogou-Yindongshan, Henan

Lead polymetallic deposit in Tudimiaogou-Yindongshan area is located in the contiguous parts of the southern margin of the North China block and the eastern part of the Qinling Mountains orogenic belt. On the basis of the previous geological data and field data collection, according to key ore controlling factors, metallogenic model and metallogenic regularity and the theory of mathematical geology, using the intelligent platform and the obtained data of geology, geophysics, geochemistry and remote sensing extract and analyze the prospecting information. The weight of prospecting indicators were obtained by AHP. By explaining and comparing the metallogenic model and indicator for exploration, using the multiple information fuzzy comprehensive evaluation method, four prospecting targets are delineated. This paper will provide theoretical support and reference for subsequent prospecting work deployment and provide technical supporting and scientific basis for further metallogenic prediction in this area.
