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.

这项研究将使用阿尔伯克基的永久性虹膜站，使用密封数字记录器和三个组件宽带地震仪。 数据将用于执行新墨西哥州里奥格兰德裂谷的地壳和上地幔结构的接收器 - 函数倒置。 要解决的问题包括中近地壳过渡的性质和可能的低速层以及上地幔的结构。 结果将提供有关岩性结构与这种活跃大陆裂谷的演变之间关系的见解，并在大陆裂谷的各种构造模型上提供约束。
