U.S.-Australia Cooperative Research: Permian Paleoclimate, Glacial Regime and Sea Level Fluctuations on the Ice-Dominated, Australian-Gondwana Shelf

该奖项将使北伊利诺伊大学的Ross D. Powell博士和一名助理能够与澳大利亚塔斯马尼亚大学的Maxwell R. Banks博士和澳大利亚阿德莱德大学的Victor A. Gostin博士在澳大利亚进行为期四个月的实地工作。该项目将重点描述澳大利亚东部塔斯曼褶皱带的塔斯马尼亚和悉尼盆地的冰川海洋沉积，并根据不同的沉积环境对这些沉积物进行解释。标准的沉积学和冰川地质学技术将用于实地研究期间在露头处收集数据和随后的实验室分析。本研究结果将进一步加深我们对冈瓦纳石炭-二叠纪冰期冰川条件和波动、气候制度以及主要海平面波动的认识。这将有助于重新评估冰架沉积的经典模型。这项工作将受益于美国和澳大利亚研究人员的互补技能。鲍威尔博士在现代冰川海洋环境方面的背景，再加上鲍威尔博士在地质领域的经验。Banks和Gostin的研究提供了正确解释该地区复杂的冰川期沉积记录所需的专业知识。

This award will enable Dr. Ross D. Powell and an assistant from Northern Illinois University to collaborate with Dr. Maxwell R. Banks of the University of Tasmania, Australia and Dr. Victor A. Gostin of the University of Adelaide, Australia during four months of field work in Australia. The project will focus on describing the glacial marine sedimentary deposits of Tasmania and the Sydney Basin in the Tasman Fold Belt of eastern Australia and on interpreting these sediments in terms of their different depositional environments. Standard sedimentological and glacial` geological techniques will be used for collecting data at outcrops during field research and for subsequent laboratory analysis. Results of this research will further our understanding of the glacial conditions and fluctuations, climatic regimes, and major sea level fluctuations during the Carboniferous-Permian glaciation of Gondwana. This will allow reevaluation of a classic model of ice shelf sedimentation. The work will benefit from the complementary skills of the U.S. and Australian researchers. Dr. Powell's background in modern glacial marine settings, when coupled with the geological field experience of Drs. Banks and Gostin, provides the kind of expertise needed to properly interpret the complex glacimarine sedimentary record of the region.
