Collaborative Research: Constraining the Petrogenesis and Mantle Source of Adare Basin Seamount Lavas

该奖项支持对罗斯海西部阿代尔角地区海山熔岩样本的研究。该地区的火山作用尚不清楚，这些熔岩的地球化学可能为区域地球动力学和全球地幔地球化学提供新的见解。由于阿代尔角海山位于海洋岩石圈上，因此它们可能不受影响大陆地区喷发的熔岩的污染。这项为期一年的调查将收集2007年在该区域航行时收集的样本数据。它将确定海山年龄，确定其地幔来源的特征，评估其起源模型，并判断进行更详细研究的可能性。就更广泛的影响而言，该项目将让研究生和本科生参加一次令人兴奋的实地考察，然后是使用尖端技术进行地球化学分析的实验室工作。

This award supports the study of lava samples from seamounts in the Cape Adare region of the western Ross Sea. Volcanism in this area is poorly understood, and the geochemistry of these lavas may offer new insight into regional geodynamics and global mantle geochemistry. Because the Cape Adare seamounts are located on oceanic lithosphere, they may be free of the contamination that affects lavas erupted through continental areas. This one-year investigation will gather data on samples collected on a cruise to this region in 2007. It will determine seamount ages, characterize their mantle sources, assess models for their origin, and judge the potential for more detailed study. In terms of broader impacts, this project will involve graduate and undergraduate students in an exciting field expedition, followed by laboratory work using cutting-edge techniques for geochemical analyses.
