A Workshop Proposal: Geodynamic Evolution of the Transantarctic Mountains and West Antarctic Rift: A Linked System

9410839 Finn该奖项支持一个名为“南极山脉和西南极裂谷的地球动力学演变：一个关联系统”的研讨会。 西南极裂谷系是一个与东南极克拉通相邻的主要大陆裂谷，而横贯南极山脉被认为是裂谷系南侧隆起的裂谷肩。 裂谷系统是特别感兴趣的，因为海洋为基础的西南极冰盖占据了该地区。 裂谷和山脉的晚中生代和新生代构造演化是最近几项由几个国家南极计划赞助的调查的主题。 这些调查表明，这些特征之间有着明显的联系，而且它们的演变过程是复杂的。 拟议的讲习班将使调查人员能够讨论今后研究的方法，以了解这一裂谷系统和邻近的横贯南极山脉的动态，并开始讨论以这一地区为重点的合作研究。 ***

9410839 Finn This award supports a workshop entitled Geodynamic Evolution of the Transantarctic Mountains and the West Antarctic Rift: A Linked System. The West Antarctic Rift system is a major continental rift adjacent to the East Antarctic craton and the Transantarctic Mountains are thought to represent an uplifted rift shoulder on the south side of the rift system. The rift system is of particular interest because of the marine-based West Antarctic Ice Sheet that occupies the region. The late Mesozoic and Cenozoic tectonic evolution of the rift and mountains have been the subject of several recent investigations sponsored by several national Antarctic programs. These investigations have demonstrated that these features are clearly linked and that their evolution has been complex. The proposed workshop will allow investigators to discuss approaches to future research to understand the dynamics of this rift system and the adjacent Transantarctic Mountains and to begin discussions about collaborative research to focus on this region. ***
