Gondwana in East Asia? A biogeographic test using Permian marine invertebrate biota

本项目将结合澳大利亚、中国东北部、俄罗斯东部和日本主要地区的二叠纪化石收集，结合详细的定量生物地理分析，为评估东亚部分构造块体古位置的现有板块构造模式提供基础数据。特别是，该项目将使用生物地理数据来检验最近提出的几个主张的有效性，即东亚大陆包含一些起源于冈瓦纳的构造块。提高对冈瓦纳大陆与东亚二叠纪古地理关系的认识，对于完善资源勘探地质模型和认识地球历史具有重要意义。

Combining Permian fossil collections from key Australian, NE Chinese, East Russian and Japanese localities, coupled with a detailed quantitative biogeographical analysis, this project will provide fundamental data for evaluating current plate tectonic models regarding the palaeo-positions of some of the tectonic blocks in East Asia. In particular, this project will test, using biogeographical data, the validity of several recently proposed claims that continental East Asia contains some tectonic blocks of Gondwana origin. An improved understanding of the Permian palaeogeographical relationship between Gondwanaland and East Asia is critical for improving geological models for resources exploration and the understanding of earth history.
