摘要
根据石牛山、石柱山实测火山构造的重力、航磁、物性、地质、地貌等特征，应用灰色系统理论中灰关联分析方法推测石牛山—石柱山晚白垩世火山构造洼地东部局部重力低异常由火山构造引起。以福建东部火山岩地区银矿找矿标志为基础，用下溪底小型银矿为模式，用灰关联分析方法分析后确定永泰立洋局部重力低异常区为银矿远景区。
The paper focuses on the application of the grey systemic theory on the large scale(1: 200000)regional gravity investigstion. Based on the characteristics of gravity anomaly, aeromagnetic anomaly,physical property, geology and land form of late Cretaceous volcanic structures in the Shiniushan and Shizhushan areas of Eastern Fujian and with the grey systemic theory, it is inferred that the regional lower gravity anomaly in Eastern Fujian results from the volcanic structures. And according to the anal ysis results of grey correlation, the regional lower gravity anomaly area in Liyang, Yongtai County is considered to be a silver-ore prospect area.
