基于GIS的有色金属成矿远景预测分析
|
摘要
随着GIS技术的发展,综合运用地质、物探、遥感等技术对难度较大的找矿工作和进行成矿预测具有重要意义。基于GIS技术,构建了普适性的有色金属成矿预测数据网络,利用大量数据进行建模分析,从而进行了信息量化的综合性有色金属成矿远景预测分析。在预测模型的基础上,通过对大瑶地区的实际应用分析还确定了12个找矿变量,以确保成矿远景预测的准确性,对进一步进行有色金属找矿工作具有重要意义。
With the development of GIS technology, it is of great significance to make comprehensive use of geology,geophysical prospecting, remote sensing and other technologies for difficult prospecting and metallogenic prediction. Based on GIS technology, a universal non-ferrous metallogenic prediction data network is constructed, and a large number of data are used for modeling and analysis, thus a comprehensive non-ferrous metallogenic prospect prediction analysis with quantitative information is carried out. On the basis of the prediction model, 12 prospecting variables have been determined through the analysis of practical application in Dayao area to ensure the accuracy of prospecting for non-ferrous metals, which is of great significance for further prospecting for non-ferrous metals.
