【摘要】 成矿预测就是应用基础地质和矿床地质的理论和有关技术方法,分析区域(或矿区)中的成矿条件和找矿信息,推断可能存在的矿床及其基本特征。GIS系统以其强大的空间信息管理和空间信息分析功能,在成矿预测中发挥着重要的作用。论文依托河南省国土资源厅地质矿产科技攻关项目“河南省深部构造基本特征与固体矿产成矿关系研究”(项目编号:豫财招标采购[2008]146-CZ),以建立数字找矿模型为切入点,对成矿预测理论、成矿预测方法和成矿预测过程进行了较全面的研究,选取了证据权模型作为成矿预测空间分析的数学模型,并对传统的证据权法加以改进,引入了专家的知识,实现了数据驱动和知识驱动的结合,设计了专家证据权数字找矿框架,并以MAPGIS组件开发技术为基础,采用Delphi7.0程序设计语言,开发数字找矿系统(Digital Mineral Resources Evaluation System,DMRES),实现多源地学信息的管理、提取、统计单元的划分、多源信息的综合等功能。论文对DMRES系统进行了测试,证实其能实现预计功能,预测结果可靠。最后论文将DMRES系统应用于河南省舞阳地区铁矿的成矿预测中,通过对河南省舞阳地区典型矿区航磁数据和重力数据进行提取、综合分析,研究河南省航磁、重力异常铁矿成矿关系,根据重磁资料,河南省舞阳地区铁矿外围地区成矿概率色块图,结合地质资料,圈定了河南省舞阳地区铁矿外围成矿远景区。更多还原

【Abstract】 The purpose of mineral resources evaluation is to analyze the regional metallogenic conditions and minerals prospecting information thus to deduce the possible deposit and its basic feature by applying theories and techniques of geoscience. Geographic Information System(GIS) plays an important role in mineral resources evaluation for its strong management function of spatial information and its powerful spatial analysis abilities.The dissertation is one part of the project named as Research on Relation between Basic Feature of deep Structures and Solid Mineral Resources in Henan province([2008]146-CZ), which is one of the key problems in scientific and technological projects from Bureau of land and mineral resources of Henan province. Full research on metallogenic prediction theory, metallogenic prediction technique and metallogenic prediction process have been made in this dissertation in order to establish a digital mineral prospecting model, then selected the weight of evidences model as the mathematical model of the spatial analysis process. Improved the weight of evidences model by introducing experts’ knowledge in it, and realized combination between data driven and knowledge driven. In this dissertation, the framework of a digital mineral prospecting model based on expert weights of evidence was constructed and a Digital Mineral Resources Evaluation System,DMRES was developed using Delphi7.0 programming languge on basis of MapGIS component technique, which contained functions of managing multi-source Geo-science information, extracting metallogenic information, dividing statistical units and as well as multi-source Geo-science information synthesis.The dissertation tested DMRES and has made sure that the anticipated functions have been accomplished and the result from it was reliable.At the end part of this dissertation, DMRES was applied to predict iron deposits of Wuyang district. Atfer analyzing and extracting aeromagnetic data and gravity data of typical iron deposits, the dissertation studied the reationship between gravity anomalies as well as aeromagnetic anomalies and potential of iron deposits. Then mapped iron deposits potential of the periphery of Wuyang iron ore in the form of color block chart, and delineated prospective areas in the periphery of Wuyang iron ore.更多还原
