Collaborative Research: Structure and Dynamics of the Crustand Upper Mantle from the Great Basin to the Great Plains

[9319008]这项研究是科罗拉多大学和内华达大学里诺分校的合作研究。它是对美国西部岩石圈结构的综合研究，从内华达州的大盆地延伸到堪萨斯州的高平原。该项目将包括对现有地震数据的分析和实地实验，以收集科罗拉多高原和东部盆地和山脉的三分量宽带地震数据。这些地区的剪切速度结构将通过远震接收函数和表面波的联合分析，以及通过远震S相的剪切波分裂的检查来检查。分析将包括重力和地形数据，以调查该地区的动力学和浮力，可能的地幔流动，以及不同地理省份之间的转换。＊＊＊

9319008 Sheehan This research is a collaborative investigation between the University of Colorado and the University of Nevada-Reno. It is an integrated study of the lithospheric structure of the western United States, extending from the Great Basin of Nevada to the High Plains of Kansas. The project will involve both analysis of existing seismic data and a field experiment to collect three- component broadband seismic data in the Colorado Plateau and eastern Basin and Range. The shear velocity structure of these regions will be examined through combined analyses of teleseismic receiver functions and surface waves, and through examination of shear-wave splitting of teleseismic S phases. The analysis will include gravity and topography data in order to investigate the dynamics and buoyancy of the region, possible mantle flow, and transitions between the various physiographic provinces. ***
