| 摘 要： | 福建省燕山旋回的成矿系列由(1)与混合岩化作用有关的成矿类型、(2)与重熔花岗岩有关的成矿类型、(3)与同熔花岗岩有关的成矿类型、(4)与超基性、基性岩有关的成矿类型、(5)与火山作用有关的成矿类型和(6)与层控有关的成矿类型等六种成矿类型组成。除第二种类型主要分布在本省西部外,其他均主要分布在东部。岩浆活动受NE、NW、ENE、E—W及N—S向断裂构造控制,而以前二者为主。火山喷发中心常出现在NE向断裂构造与NW或ENE向断裂构造交汇处。燕山旋回的成矿作用与其构造岩浆活动有关。本文最后提出了本成矿系列的

| Abstract: | The Yanshanian metallogenic series in Fujian consists of 6 metallogenic types, i. e. (1) mineralization related to the granitoid of migmatization, (2) mineralization related to the granitoid of anatexis type, (3) mineralization related to the granitoid of syntexis type, (4) mineralization related to ultrab-asic and basic igneous rocks, (5) mineralizatior) related to volncaism, and (6) mineralization related to strataboundness. The second type is mainly distributed in the western part of the province, while the othors mainly in the east. Magmatic activies are controlled by fractures, trending NE, NW, ENE, and N-S, with the first two dominant. Eruption centers usually occur at the intersections of .NE-and NW-or ENE-trending fault zones. So the mineralization of Yanshanian is closely related to the tectonic magmatic activities. Model of metallogenic series in Yanshanian and metallogenic predication in this province are given in this paper. |
