Abstract

"Over the past decades, the seismic structure of the crust and upper mantle of the southwestern United States was examined using an array of different methods. The structure and composition of crust received special attentions, most due to the hydrocarbon reserves in this area. Here new constraints on crustal evolution and structure models are provide by systematically analyzing 37,402 receiver functions recorded at 234 seismic stations on the southwestern United States. The results reveal that the Transitional Crust is characterized by a thin (29.0±1.0 km) crust, a low Vp/Vs ratio of 1.76±0.016 and a high amplitude (R) of P-to-S converted waves (relative to that of the direct P wave) of 0.258±0.028, consistent with the model that the thin crust was the consequence of lithospheric stretching during the opening of the Gulf of Mexico and that this area is covered by a thick sedimentary layer."--Abstract, page iii.
