| 摘 要： | 辽东复县和鲁西蒙阴金刚石原生矿带产于中朝准地台的胶辽台隆次级凸起与凹陷的衔接带。胶辽台隆自晚前寒武纪以来,经历了扬子、晚加里东、华力西、印支、燕山等构造岩浆旋回,并在地台多旋回升降运动中,由于地壳产生减薄和水平引张作用,使富镁铁橄榄岩浆沿岩石圈断裂反复上涌,充填于基底断裂和盖层断裂中,形成了金伯利岩管和岩脉。依此,金刚石的成矿作用可划分为4个旋回;前寒武纪成矿旋回;加里东成矿旋回;华力西成矿旋回;燕山成矿旋回,其中以晚加里东—华力西成矿旋回和燕山成矿旋回最为重要。

| Abstract: | The primary diamond zones of Fuxian in eastern Liaoning and Mengyen in western Shandong occured at the secondary upwarping and downwarping joints in Jiao-Liao platform uprise of Sino-Korean paraplatform. Since the late Precambrian, Jiao-Liao platform uprise had undergone Yangtze, the late Caledo nian, Yariscian, Indo-Sinian and yamshan tectonomagmatic cycles. In the polycyelic up and down movement of the platform, because of the mute and horizontal tension by crust, mafic-rich olivine magma welled repeatedly and spirally along the lithosphere fracture, filled up the base mental and overlying strata fracture and formed the kimberlite pipes and veins. The polyeyclic metallogensis of diamonds in Jiao-Liao platform uprise could be divided into four cycles, the Precambrian, Caledonian, Variscian and Yanshan, all of which except the Precambrian were very important. |
