| 摘 要： | 对分布于华北板块东缘的辽宁铁岭、瓦房店及山东蒙阴等3个金伯利岩区的地质构造特征进行了研究，利用地层时代、构造行迹、古地磁以及同位素资料，对该区域金伯利岩的侵位时间进行了综合约束，认为该区域金伯利岩的侵位时间应该在250-300 Ma 之间。在此基础上，结合华北板块与扬子板块在古生代时的相互运移特征，对华北板块东缘金刚石的成矿区域地质背景进行了分析，并结合构造形迹的研究，对该区域金刚石原生矿进行了成矿预测。

| Abstract: | Geological structural characteristics of Tieling and Wafangdian kimberlite in Liaoning province and Mengyin in Shandong province in eastern margin of North China plate have been studied.By using stratigraphic age,tectonic deeds,paleomagnetic and isotopic data,emplacement time of kimberlites in the region has been constrainted comprehensively.It is regarded that emplacement time of kimberlite in this region should be between 250-300 Ma.On this basis,combining with migration characteristics of North China plate and Yangtze plate during Paleozoic period,regional geological background of diamond mineralization regions in eastern margin of the North China Plate has been analyzed.Combining with the study on the structural trace,metallogenic prediction of diamond primary ore has been carried out as well. |
