Tectonic subsidence, geoid analysis, and the Miocene-Pliocene unconformity in the Rio Grande Rift, Southwestern United States; implications for mantle upwelling as a driving force for rift opening

We use tectonic subsidence patterns from wells and stratigraphic sections to describe the mid-Miocene to present tectonic subsidence history of the Rio Grande rift. Tectonic subsidence and therefore rift opening were quite fast until ca. 8 Ma, with net subsidence rates (∼25-65 mm/k.y.) comparable to...
