摘　　要： 安徽庐枞地区(1500km^2)范围内有104处脉状矿床、矿化点及44处铜的地球化学异常区,但是目前只有4处小型铜(金)矿床.对区域成矿地质背景、脉状矿床分布规律、有经济意义的矿床形成条件和矿床成因的系统研究证明:庐枞地区形成脉状铜(金)矿化的矿源、水源及能源较充足,但成矿物质未能在小范围内被集中,大量成矿元素被分散,因此,庐枞火山-构造洼地内外缺少形成大型、超大型铜矿的条件,大量的矿点、矿化点和广泛分布的地球化学异常,在一定条件下是成矿元素被分散的标志,不是形成大型、超大型矿床的有利标志. There are 104 copper vein mineralized areas and 44 geoehomieal abnormals in Lujiang-Zhongyang district (1500km), but only 4 small productive ore deposits are so far discovered. The studies on geological setting, distridution regularities, forming conditions of productive ore deposits and genesis of copper (gold) vein mineralization have shown that the sources of ore-forming elements, driving energy and water of the hydrothermal system are enough, but the ore-forming materials have not been concentrated on a small area, and a lot of copper (gold) have been dispersed, so there are lack of the forming conditions for large or huge size of copper (gold) deposits in the Lujiang-Zhongyang volcanic-structural depression, therefore a lot of mineralized areas and geochemical abnormals may not be the sign of large or huge ore-deposits and be the sign of dispersion of ore-forming elements in some cases.
