德化—尤溪地区金矿潜在资源量初步估算

Preliminary Estimation of the Potential Gold-ores Reserve in the Dehua-Youxi Area

德化—尤溪地区是福建省重要的金矿成矿区。通过综合成矿信息提取、筛选出与金矿成矿作用密切相关的成矿信息标志 ,应用信息量计算法、特征分析法 ,优选出金矿找矿靶区 10处 ,其中 A类 2处 ,B类 2处和 C类 6处。在优选出的找矿靶区内 ,采用一元线性回归分析法和蒙特卡洛法模拟概率分布曲线 ,分别估算出该区金矿潜在资源量分别为 91.3t和 96 .

The Dehua Youxi area is an important metallogenic province of gold ores in Fujian Province.Based on the ore forming information indicators closely related with gold mineralization by the selection and extraction of the comprehensive ore forming information and using the methods such as information flow calculation and characteristic analysis,the author selected ten ore hunting targets of gold ores,in which there are 2 targets for Grade Ⅰ,2 for Grade Ⅱ and 6 for Grade Ⅲ.By using the unary linear regression analysis and the Monte Carlo method,it is estimated from the 10 optimized ore hunting targets that the potential reserves of gold ores in the surveyed area are 91 3 tons and 96 7 tons,respectively.
