华北晚古生代沉积记录着冰期-间冰期转换的信息,其火山事件沉积研究一直是热点,主要通过4个方面(火山事件沉积类型及特征、火山事件沉积的识别方法、火山事件沉积对比及火山源分布、火山碎屑搬运机制)总结了过去30多年华北晚古生代火山事件沉积研究成果,详细地综述了每个方面的研究进展,综合得出了华北晚古生代火山事件沉积未来的5个可能研究方向:(1)不同时空尺度下的多种类型火山事件沉积分布;(2)多手段相结合的火山事件沉积识别方法;(3)大尺度区域的火山事件沉积对比格架构建以及火山源分布和性质;(4)多种因素共同控制的火山碎屑的搬运机制;(5)火山时间沉积的年代学研究。进而指出未来每个方向的研究可能采用的研究方法,为华北晚古生代深时古气候及基础沉积学理论研究提供一定的基础。

There were information transferred from the Glacial Epoch to the Interglacial Epoch recorded in the Late Paleozoic sedimentation in North China and a study on the volcanic event sedimentation always was a hot spot.With the four aspects (of the volcanic event sedimentation type and features,volcanic event sedimentation recognition method,volcanic event sedimentation comparison and volcano source distribution,pyroclastic transportation mechanism) mainly,the paper summarized the study achievements on Late Paleozoic volcanic event sedimentation in North China in the passed over 30 years and in detail stated the study progress on each aspect.There were five possible feature study orientations of the Late Paleozoic volcanic event sedimentation in North China comprehensively obtained,including ① a multi type volcanic event sedimentation distribution under different space-time dimension,② multi means combined volcanic event sedimentation recognition method,③ comparison framework establishment of the volcanic event sedimentation in a large dimension region and the volcano source distribution and property,④ the pyroclastic transportation mechanism under the joint control of the multi factors and ⑤ the chronology study on the volcano time sedimentary.Therefore the paper pointed out the possible applied study method of each future orientated study.The paper could provide a certain base to the theoretical study on the deep ancient climate and base sedimentation theory of the Late Paleozoic in North China.
