摘要: 围绕岩石圈破坏和减薄这个主题，华北克拉通成为近10年来国内外研究的热点地区。华北克拉通中生代以来基性岩墙群分布广泛，然而对此仍缺乏系统的研究。通过对基性岩墙群的系统总结，在详尽的资料收集和已有研究的基础上，重点对华北克拉通中生代基性岩墙群的研究现状、分布和意义进行了汇总和讨论。随后，结合近年来的研究经验，提出了基性岩墙群定年中应注意的问题。

Abstract: Due to the topic of lithospheric thinning and destruction, the North China Craton (NCC), where the mafic dyke swarms since Mesozoic is widely distributed, has intensively regarded in recent literature. Systemic investigation on these swarms, however, is still scare. Based on the comprehensive summary, detailed data acquisition and informed research, a major discussion has been given in this paper for the Mesozoic mafic dyke swarms in NCC, including the current situation, distribution and significance. Moreover, some suggests on the dating of mafic dyke swarms also have been proposed.
