Tectonic Controls on Formation and Evolution of Permian Depositional Basins in the Transantarctic Mountains as Interpreted from Strata Exposed Areas.

该奖项支持对横贯北极山脉中暴露的地层进行调查，这些地层是在晚古生代和早中生代期间在冈瓦内德造山带附近发育的一个主要前陆盆地中沉积的。主要特征包括暴露在横贯北极山脉中部的前陆盆地；假想的古地理高点；以及暴露在维多利亚大陆南部的克拉通内盆地。由于缺乏宁罗德冰川和伯德冰川之间地区的数据，这些盆地和高地之间的关系尚未解决。拟议的沉积学和地层学分析将识别和对比单元，并确定控制这两个盆地的形成、演化、沉降和沉积的因素。

This award supports an investigation of the strata exposed in the Transantarctic Mountains which were deposited in a major foreland basin that developed adjacent to the Gondwanide orogenic belt during the late Paleozoic and early Mesozoic. Major features include the foreland basin, exposed in the central Transantarctic Mountains; a hypothetical paleogeographic high; and an intracratonic basin, exposed in southern Victoria Land. Relationships between these basins and the high are unresolved due to a lack of data in the area between the Nimrod and Byrd Glaciers. The proposed sedimentologic and stratigraphic analysis will identify and correlate units and determine the factors that controlled the formation, evolution, subsidence and sedimentation in the two basins.
