| 摘 要： | 与华南一样，在华北克拉通北缘及其增生带也有与盆地流体有关的矿床产出。矿床的生成总是与张裂型沉积盆地有关。根据基底大地构造性质和盆地动力学演化特征，可划分出两个与盆地流体有关的、特征各异的金属成矿省：1)华北克拉通北部元古代金．多金属成矿省，在克拉通内部，边缘元古代裂谷增生期生成沉积喷流型硫多金属矿床和沉积岩容矿的微细浸染型金矿床；2)大兴安岭中南段古生代锡．多金属成矿省，在克拉通北缘早／晚古生代增生带的张裂型沉积盆地内分别生成各具特征的铅锌/锡-多金属矿床。 |

| Abstract: | WT5BZ]There occur ore deposits formed by basin fluids in the northern margin of North China Craton (including its northern crustal growth zone during Paleozoic), and the ore formation always related with rifting basins, just like the situation of Yangtze Craton in South China. According to evolutional dynamics characteristics of sedimentary basin , there are two metallogenic provinces in connection with basin fluid ore formation in the northern margin of North China Craton:1) Proterozoic Au polymetallic province in the northern part of the craton, where sedex type Pb Zn polymetal deposits and sediment hosted micro disseminated gold (SMG) deposits were formed by basin fluids in Proterozoic rifting basins;2) Paleozoic Sn polymetallic province in the northern accretionary zones of the craton, where Pb Zn and Sn polymetallic deposits were formed in Paleozoic basins with extensional tectonic background. |
| Keywords: | basin fluid sedex deposit SMG deposit North China |
