| [摘要]以地质、地球物理勘探、地球化学勘探、遥感等手段获取的多源数据,经过发现、提取、转换和关联,并利用信息综合技术建立区域综合信息矿产预测模型,进行矿产资源定量评价,是当前矿产资源勘查领域信息找矿的重要途径。本文在对内蒙古赤峰市克什克腾旗地质背景与成矿规律进行研究的基础上,利用GIS 技术进行区域成矿专题信息分析与提取,建立评价证据指标模型,使用证据权重法对该区有色金属进行了成矿预测,实践证明利用GIS 对研究区开展多源地学信息综合管理,并使用证据权法对区域控矿因素进行统计计算,可以实现综合致矿信息的集成,是区域成矿预测与评价的重要技术和方法手段,同时指出研究区具有进一步找矿的潜力。 |

| Abstract:Recently, an important approach for mineral resources prospecting and exploration has emerged. It includes obtaining multi-source data by methods of geological, geophysics, geochemistry, and remote sensing; discovery, extraction, conversion and correlation of the multi-source data; and development of a metallogenic prediction model integrated with comprehensive information techniques. Taking the Keshenketeng Qi area in Inner Mongolia as
an example, based on its geological setting and metallogenic regularities, this paper analyzes and extracts the comprehensive metallogenic information by
GIS technique, and develops a weighted evidence model. Then we perform metallogenic prognosis in the study area. The practice proves its metallogenic significance as an important technique and method. Meanwhile we point out a prospecting potential in the investigated area. |
