Triassic Paleosols, Paleoclimate and Vegetation of Antarctica

9315228 Retallack该奖项支持对南维多利亚陆地和横跨北极山脉的沙克尔顿冰川地区的三叠纪古土壤进行研究，以提取有关气候条件和现存植被的信息。众所周知，南极洲的这一部分代表了三叠纪时处于接近极地位置的大陆内部环境。这一地区非常宜人，足以支持阔叶林以及大型两栖动物和爬行动物。然而，有助于区分例如林地和灌木地的古环境的细节仍然不清楚。在世界许多地区对第四纪古土壤进行了详细的研究，这对了解古环境非常有用。目前，将这些类型的研究扩展到三叠系是可行的。南极洲三叠纪古土壤与温带地区第四纪和现代土壤的对比将有助于我们对气候条件和生态系统的了解，并将为全球环流气候模型提供重要信息。***

9315228 Retallack This award supports a study of Triassic paleosols in South Victoria Land and in the Shackleton Glacier area of the Transantarctic Mountains in order to extract information about climatic conditions and about extant vegetation. This part of Antarctica is known to represent a continental interior environment that was in a near polar position during the Triassic. This region was hospitable enough to support broadleaf forests as well as large amphibians and reptiles. However, details of the paleoenvironments that would help differentiate between, for example, woodland and shrub-land remain obscure. Detailed study of Quaternary paleosols in many parts of the world has proved very useful to understanding paleoenvironments. Extension of these types of studies to the Triassic is feasible at this time. Comparison of Triassic paleosols from Antarctica to Quaternary and recent soils from temperate regions would improve our understanding of climatic conditions and ecological systems and would provide important information for global circulation climate models. ***
