| 摘 要： | 冀北（京津）地区金（银）矿的成矿主要受古隆起及长期活动的东西向深大断裂带控制.在古隆起内部及边缘发育的近东西向和北东向深断裂的交汇部位，形成了多个金（银）等多金属矿化集中区.与金（银）矿成矿关系密切的岩浆活动主要为燕山期，其次为海西期.金（银）矿化多位于岩浆作用形成的中酸性岩体附近或岩体之间.太古宙变质岩系中的“角闪质”岩石的金（银）元素背景值普遍较高，为本区的主要矿源层，角闪岩相是含金（银）的主要岩相.金矿成矿为多期、多次叠加，主要成矿时代为海西期和燕山期，其中燕山期较为重要，是区域金、银、铜、铅、锌成矿的主要时期.

| Abstract: | The metallogenesis of the gold (silver) deposits in Northern Hebei (Beijing-Tianjin) region is mainly controlled by old domes and long-lasting active E-W-trending deep faults. Quite a few gold-silver-polymetal mineralization concentrating areas are formed in the intersections of the E-W-trending and NE-trending deep faults, which are developed inside and on the rims of the domes. The metallogenesis of the gold (silver) deposits is closely related to Yanshanian magmatism, followed by Hercynian magmatism. The... |
