摘要
该文基于胶东地区丰富的地质、物化探资料,通过建立GIS地质数据库,实现对各类地质空间数据综合分析,了解地质实体之间的相互关系,掌握各种地质异常与金矿分布的关系。运用MapGIS地理信息系统的空间分析方法,对金矿成矿与找矿密切相关的地质异常信息进行提取、叠加,形成组合地质异常,并运用组合地质异常进行金矿成矿预测研究。
Regarding gold deposit concentration area as studying object and GIS as the basic plate, abnormal information for ore--probing are conducted. Structure, strata, magmatic rock, geophysical and geochemical information which have close relation with ore--forming are picked up. By dint of GIS spacial information analysing function, Jiaodong area is divided into 6 ore--foming future areas. Through strengthening predication, 10 Ⅰ degree predication areas, 18 Ⅱ degree predication areas, and 17 Ⅲ degree predication areas are circled in gold deposit concentration areas in Jiaodong area.
