基于多元信息的证据权法在南岭钨锡多金属成矿预测中的应用
Application of weights of evidence method for prediction of W-Sn polymetallic deposits based on multi-source information in Nanling metallogenic belt
摘要
Abstract
According to1:500000 geological database, geophysical and geochemical exploration data in Nanling metallogenic belt, all kinds of related maps were compiled by data-processing, analyzing and interpreting. On ba-sis of the GIS platform, guided by the geological anomaly theory, all favorable ranges of prospecting factors were selected through multi-information metallogenic coupling analysis and anomalous information extraction. Finally, 13 effective evidence layers were built. Ore-forming quantitative prediction and assessment was done based on weights of evidence of Morpas and Arc-wofe model. According to the critical value of 0.024、0.078 and 0.098, 41 for prospecting,70 secondary prospect areas and 85 triple prospect areas were submited, it was significanct to plan work and plan mineral resources in the region.关键词
