High Resolution Natural Source Imaging of the Colorado Plateau Crust-Mantle Structure

小行星9628043 这项研究涉及使用新获得的PASSCAL地震宽带数字数据，以提高科罗拉多高原的岩石圈结构的知识，并解决科罗拉多高原隆起的起源。 这一未解决的新生代隆起发生在高原在其17亿年历史的大部分时间里基本上保持在海平面之后。 拟议的分析将涉及建设共同的中点堆栈的接收器功能，测量的反射P和S波的旅行时间，测量Pn旅行时间从两个深探测枪，和剪切波分裂测量的4个合适的SKS事件记录。 结果应提供莫霍面深度，地壳和上地幔速度，地震速度各向异性由于化石应变和/或重结晶过程的信息。 ***

9628043 Dueker This research involves use of newly acquired PASSCAL seismic broad-band digital data to improve knowledge of the Colorado Plateau's lithospheric structure and address the origin of the Colorado Plateau's uplift. This unresolved Cenozoic uplift occurred after the plateau remained essentially at sea-level for most of its 1.7 billion year history. Proposed analysis will involve construction of common midpoint stacks of receiver functions, measurement of teleseismic P and S wave travel times, measurement of Pn travel times from two Deep Probe shots, and shear-wave splitting measurements for the 4 suitable SKS events recorded. The results should provide information on Moho depth, crustal and upper mantle velocities, and seismic velocity anisotropy due to fossil strain and/or recrystallization processes. ***
