This research will use the PASSCAL digital recorders and three- component broadband seismometers along with the permanent IRIS station at Albuquerque. Data will be used to perform receiver- function-method inversion for crustal and upper mantle structure along the Rio Grande Rift in New Mexico. Questions to be addressed include the nature of the mid-crustal transition and possible low-velocity layer and the structure of the upper mantle. The results would provide insights into the relationship between lithologic structure and evolution of this active continental rift and provide constraints on various tectonic models of the continental rift.

这项研究将使用 PASSCAL 数字记录仪和三分量宽带地震仪以及阿尔伯克基的永久 IRIS 站。 数据将用于对新墨西哥州里奥格兰德裂谷沿线的地壳和上地幔结构进行接收函数方法反演。 需要解决的问题包括中地壳转变的性质和可能的低速层以及上地幔的结构。 研究结果将为了解该活动大陆裂谷的岩性结构与演化之间的关系提供见解，并为大陆裂谷的各种构造模型提供约束。
