摘　　要：闽西北中生代花岗岩总体上可分为重熔型和同熔型两种类型。根据研究区两种类型花岗岩产出构造部位 ,成岩物质来源以及成矿元素本身地球化学属性之间的差异 ;结合岩矿石多元素统计分析 ,岩石稀土元素特征及其配分型式 ,单矿物微量元素比值 ,铅同位素、氢氧同位素特征等 ,较系统地阐述了闽西北地区重熔、同熔型花岗岩类的成矿特点。Mesozoic Era granites in northwestern Fujian can be generally classified into two types: remelting type and syntectic type. Based on the produced structure position of the granites of the two types, diagenetic materials source and the difference of the geochemical attributes of the metallogenetic elements in the studying area, combining the statistical analysis of rock and mineral poly element, characteristics of rock REE and its distribution pattern, microelement ratio of single mineral, lead isotope and oxyhydrogen isotope characteristics and so on, this paper systematically discusses the metallogenetic characteristics of granites of the two types in northwestern Fujian
