摘　　要：冀西北水泉沟岩体具有分布范围较广、岩石类型多样、成因复杂的特征,既是华北克拉通北缘地区典型的碱性岩体之一,又是区域金矿的主要赋矿场所,因而备受广大地质学者的关注。为了综合研究岩体与金矿的关系,对前人成果进行了归纳总结,通过分析岩体的岩石类型、岩石化学成分、金矿地质特征和岩体与金矿的时空、成因关系等,认为岩体总体属于海西期钙碱性、弱碱性和碱性岩石共存的杂岩体,区域金矿主要受构造控制,成矿与岩体成岩有一定的时空和成因关系。在此基础上,指出了本区岩体与金矿研究领域现存的主要科学问题,并强调燕山期成矿事件应引起重视、深入研究。The Shuiquangou rock mass in northwestern Hebei province is characterized by wide distribution,various rock types and complex genesis.It is not only one of the typical alkaline plutons in the northern margin of the North China Craton,but also the main ore-hosting site of regional gold deposits,so it has attracted the attention of geologists.In order to comprehensively study the relationship between rock mass and gold deposit,this paper summarizes the previous achievements.Through the analysis of rock type,petrochemical composition,geological characteristics of gold deposit and the space-time and genetic relationship between rock mass and gold deposit,it is considered that the rock mass generally belongs to the Hercynian calc alkaline,weakly alkaline and alkaline complex,and the regional gold deposit is mainly controlled by structure.There is a certain time-space and genetic relationship between mineralization of gold deposits and diagenesis of rock mass.On this basis,the main existing scientific problems in the research field of rock mass and gold deposit in this area are pointed out,and it is emphasized that the Yanshanian metallogenic events should be paid attention to and studied in depth.
