SGER:Exploratory Research on the Timing of Early Paleozoic Orogenesis along Gonwana's Paleo-Pacific Margin, Queen Maud Mountains, Antarctica

这一探索性研究的小额赠款调查了南极洲莫德王后山脉的起源，以了解形成冈瓦那的地球动力学过程。不同岩石单元的年龄将通过锆石的LA-MC-ICPMS分析和角闪石的40Ar-39Ar分析来确定。S项目的目标是研究时间变形、沉积单元沉积、岩浆作用和区域冷却。结果将与澳大利亚的相关岩石单位进行关联。通过限制过程的长度和时间尺度，结果将提供对导致变形的地球动力学过程的洞察，例如板坯回滚或拉伸。此外，测定这些沉积单元的年代可能会提供对寒武纪生命爆发的洞察，因为人们推测，这些山脉的侵蚀造成的沉积物通量为海洋播撒了有机体发育坚硬身体部分所需的营养物质。更广泛的影响包括对本科生研究的支持。

This Small Grant for Exploratory Research investigates the origin of the Queen Maud Mountains, Antarctica, to understand the geodynamic processes that shaped Gondwana. Ages of various rock units will be determined using LA-MC-ICPMS analyses of zircons and 40Ar-39Ar analyses of hornblende. The project?s goal is to time deformation , sedimentary unit deposition, magmatism, and regional cooling. Results will be correlated with related rock units in Australia. By constraining the length and time scales of processes, the outcomes will offer insight into the geodynamic processes that caused deformation, such as slab roll-back or extension. In addition, dating these sedimentary units may offer insight into the Cambrian explosion of life, since the sediment flux caused by erosion of these mountains is conjectured to have seeded the ocean with the nutrients required for organisms to develop hard body parts. The broader impacts include support for undergraduate research.
