| 摘 要： | 对华北地块北缘的金矿进行了成因分类,共分为3大类7亚类.利用地质体单元法对3大金矿类型进行了单元划分,共划分出214个单元.在综合信息成矿理论的指导下,对本区的岩浆重熔热液型金矿、岩浆同熔热液型金矿床以及火山-次火山热液型金矿床分别采用特征分析,对矿产资源的产出位置进行了估计,采用成矿概率估计对各单元的成矿可能性进行分级,共预测出24个最有远景的工作区.

| Abstract: | Three main types and seven subtypes have been geneticaly divided for the gold deposits at the northern margin of the north China platform. 214 units have been recognized using geological unit methods for the three main types of gold deposits in the area. Under guidance of synthetic information metallogenic theory, the authors have carried out the character analysis for the three types of gold deposits in the area: remelted-magmatic hydrothermal, systecnic magmatic hydrothermal and volcanic-subvolcanic hydrothermal. Based on the estimation on the most possible occurrence locations and the metallogenic probabilities of different units, 24 units are concluded to be mostly perspective. |
