基于GIS的多元信息成矿预测研究在湖南锰矿预测中的应用

Application of multi-information metallogenic prediction based on GIS to manganese ore prediction in Hunan Province

应用GIS技术并结合地质、地球物理、地球化学、遥感等资料进行综合信息成矿预测是目前找矿的一个重要趋势。以湖南省锰矿资源成矿预测研究为例,在总结区域成矿规律的基础上,以地质异常致矿理论为指导,利用GIS平台提取地质、地球物理、地球化学等多元地质找矿信息,采用证据权模型进行多元找矿信息的综合,对湖南省的有利成矿区进行锰矿预测。

Application of the GIS technology combined with comprehensive geological,geophysical,geochemical and remote sensing information to do metallogenic prediction data is an important trend of the present prospecting.Taken the manganese ore prediction in Hunan as an example,the study used GIS platform to extract geological,geophysical and geochemical multivariate information,and utilized the weights of evidence modeling to integrate this comprehensive information to predict the favorable prospecting areas,based on the summary of regional metallogenic regularity and ore geological anomaly theory.
