地学信息三维定量化提取与集成——以河南栾川钼矿区为例

三维地质建模与找矿靶区优选是当前国际地学研究的热点和难点。利用三维可视化技术和数学建模方法,通过自主研发GeoCube三维矿产资源预测与评价软件,实现了栾川钼矿区三维地学信息定量化提取与集成。在此基础上,开展多种数学建模方法集成对比及其网格单元划分的不确定性分析,认为证据权法具有稳健的三维空间集成分析特征,其三维环境中的预测远景靶区为该区深部找矿定位、定量研究提供了科学依据。研究成果为中国老矿山深部成矿定量预测技术方法研究提供借鉴。

Three dimensional quantitative extraction and integration for geosciences information: A case study of the Luanchuan Mo ore district

Three dimensional (3D) geological modeling and optimization of prospecting targeting constitute the hotspot and difficulty in the current international geosciences research. In this paper, 3D visualization technology and mathematical modeling method were utilized through independent research and development of GeoCube software for mineral resources prediction and evaluation, and the molybdenum targeting based on 3D geological information quantitative extraction and integration was realized. On such a basis, the integrated comparison was carried out by a variety of mathematical modeling methods and the uncertainty analysis of grid cell division. The weight of evidence has the characteristics of steady 3D integrated analysis, and the prediction of the targets in the 3D environment can realize deep prospecting positioning and provide a scientific basis for quantitative research. The research results presented in this paper can be used for deep ore-forming quantitative prediction technological research in old mines of China.
