GIS 在地质勘查成矿预测应用中的技术方法探讨

摘要

GIS has played an important role in geological prospecting, and its advantage presents in several aspects below: 1. it can analyze geological conditions for mineralization rapidly and finds out favorable numerical range for mineralization by application data retrieval; 2. through comprehensively analyzing geological anomalies and prospecting posibility, it can establish metallogenic prediction model by spatial analysis methods; 3. it can provide spatial information primarily in graphic images and attribute information in words so that the analysis result can be more quantified, evident and effective.%GIS 技术在地质找矿中发挥着重要作用，它的优势体现在可以快速分析成矿地质条件，应用数据检索找出有利于成矿的数值区间；通过对地质异常和找矿有利度的综合分析，运用空间分析手段，建立成矿预测模型；提供以图形图像为主的空间信息和以数字、文字为主的属性信息，从而使得分析结果更定量化、直观和有效果。
