This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).The most dramatic geologic events - such as earthquakes and volcanic eruptions - occur along the margins of the mosaic of plates that cover the surface of the Earth, and are a consequence of plate motions. Plate motions also affect mountain building, sea level, and climate. Hence, unraveling the history of plate motions is a matter of considerable importance for understanding much of the Earth?s history. The objective of this research is to use newly-available Russian data from the Mid-Atlantic Ridge to develop detailed models of motions between the India, Eurasia, Nubia (West Africa) North America, and Pacific Plates over the last 20 million years. With their improved spatial and temporal resolution, these models will be useful to a broad cross section of the science community who seek linkages between plate motions, continental tectonics, and climate; they will also provide a framework for understanding the evolution of western North America, the Himalaya, and the Alps. The program will also continue an established international collaboration between U.S. and Russian scientists.

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。最引人注目的地质事件-如地震和火山爆发-发生沿着覆盖地球表面的板块镶嵌边缘，是板块运动的结果。板块运动也影响着造山运动、海平面和气候。因此，揭开板块运动的历史对于了解地球的大部分情况是相当重要的。的历史。这项研究的目的是利用新获得的俄罗斯中大西洋海岭数据，开发印度，欧亚大陆，努比亚（西非）北美和太平洋板块在过去2000万年间运动的详细模型。这些模型在空间和时间分辨率上的改进，将有助于科学界寻求板块运动、大陆构造和气候之间联系的广泛领域;它们还将为理解北美西部、喜马拉雅山和阿尔卑斯山的演化提供一个框架。该计划还将继续美国和俄罗斯科学家之间建立的国际合作。
