英文摘要	依据古地磁方法，对志留纪全球古板块进行再造，并在此基础上叠加了更新的志留纪全球大地构造背景、洋流系统、气候带分布以及岩相古地理、烃源岩分布等要素，编制了志留纪全球古板块再造图、全球古地理图、全球岩相古地理及烃源岩分布图。志留纪全球板块构造格局最重要的特点是劳俄大陆的形成以及冈瓦纳大陆北缘的持续裂解事件。早—中志留世全球性的海侵事件导致各大板块周缘普遍发育陆表海，碳酸盐岩台地广泛分布于冈瓦纳大陆的周缘以及西伯利亚板块和劳俄大陆的大部分。志留纪较高的温度以及广阔的陆表海促进了海洋生物的进一步繁盛，为烃源岩的发育提供了丰富的母质；同时，上升流作用以及冈瓦纳大陆内部大型河流的搬运作用，导致在冈瓦纳大陆的西缘（北非和阿拉伯地区）发育有厚层的黑色页岩，其为志留系重要的烃源岩。; Based on the method of palaeomagnetism,we reconstructed the global plates in Silurian. Furthermore,we added some updated data such as the global tectonic setting,global current system,dis-tribution of climate zone,lithofacies palaeogeography and distribution of source rocks in Silurian to the map of global palaeo-plate reconstruction,so the map of global palaeogeography and the map of global lithofacies and distribution of source rocks in Silurian were compiled.The most important characteristics of global plate tectonics in Silurian is the assembly of Laurussia continent and the long-term breakup event oc-curred in the north of Gondwana.The global scale transgression events in Early-Middle Silurian resulted in epicontinental sea widely developing in the periphery of each plate,so carbonate platform widely distribu-ted in the periphery of Gondwana and most areas of Siberia and Laurussia in Silurian.High temperature and a wide range of epicontinental sea made contribution to the prosperous of creatures in Silurian,which offered abundant petrologen for the development of source rocks.In addition,the effects of upwelling cur-rent and transportation of large rivers in Gondwana resulted in the development of thick black shales in the west of Gondwana (North Africa and Arabia),which is the most important source rocks in Silurian.; 国家重点基础研究发展计划“973计划”项目(编号2009CB219302)资助。; 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 2; 185-196; 18
