Collaboration: A High Resolution Piggyback for PACE 1992: Imaging Enigmatic Crustal Features in Southeastern California

这项研究是为了支持美国地质勘探局赞助的现有项目PACE(太平洋-亚利桑那州地壳实验)的一个搭载地震实验。来自工业和PASSCAL阵列的地震仪器将在三次部署中使用，总共41次由美国地质勘探局进行。背靠背将产生两个高分辨率的低褶皱P波和S波剖面：一个是横跨帕洛维德山脉、中途山、巧克力山和巧克力山逆冲断层的50公里长的倾角剖面。另一条是沿巧克力山逆冲的27公里斜向走行线。目标包括描绘地壳结构，一直到莫霍面，以及奥罗科普片岩建造的关系和性质。

This research is to support a piggyback seismic experiment to an existing program PACE (Pacific-Arizona Crustal Experiment) sponsored by the USGS. Seismic instruments from industry and the PASSCAL array will be utilized in three deployments for a total of 41 shots by the USGS. The piggyback will produce 2 high- resolution low-fold P and S wave sections: one is a 50 km long dip profile across the Palo Verde Mountains, the Midway Mountains, the Chocolate Mountains, and the Chocolate Mountains thrust fault. The other is a 27 km oblique strike line along the Chocolate Mountains thrust. The goals include delineation of crustal structure down to the Moho and the relation and properties of the Orocopia schist formation.
