Reconstruction of the Transantarctic Mountains Foreland Basin

在横贯北极和埃尔斯沃斯山脉的上古生界-下中生界层序中，发现了南极古太平洋边缘源区和构造性质的间接证据。本次调查的主要目的是综合南极地区的盆地研究。这将通过汇编古流和物源数据，比较不同地区的沉积相，以及将相对暴露较少的南极盆地与其他冈瓦那大陆古太平洋边缘较知名的盆地进行比较来实现。整合这些数据的工作假设是，南极盆地是一个更大的前陆盆地的一部分，该盆地是响应南极西部二叠-三叠纪的褶皱和逆冲而发展起来的。这项工作的一部分将与澳大利亚悉尼麦格理大学的贡德瓦南前陆盆地项目合作进行。

Indirect evidence of the nature of source terrains and tectonism along the paleo-Pacific margin of Antarctica is found in the upper Paleozoic-lower Mesozoic sequence of the Transantarctic and Ellsworth Mountains. The major objective of this investigation is the synthesis of basin studies in the Antarctic. This will be achieved by compilation of paleocurrent and provenance data, comparisons of sedimentologic facies in various regions, and comparison of the relatively poorly exposed Antarctic basins with the better known basins along the paleo-Pacific margin of other Gondwana continents. The working hypothesis for the integration of these data is that Antarctic basins are part of a larger foreland basin which developed in response to Permo-Triassic folding and thrusting in West Antarctica. Part of this work will be carried out in collaboration with Gondwanan Foreland Basin Project at Macquarie University, Sydney, Australia.
