A high-resolution, regional passive seismic experiment in the Rio Grande rift region of the southwestern United States has produced new images of upper-mantle velocity structure and crust–mantle topography. Synthesizing these results with geochemical and other geophysical evidence reveals highly symmetric lower-crustal and upper-mantle lithosphere extensional deformation, suggesting a pure-shear rifting mechanism for the Rio Grande rift. Extension in the lower crust is distributed over a region… 

Small-scale convection during continental rifting: Evidence from the Rio Grande rift

Recent seismic imaging across the Rio Grande rift, western United States, revealed unexpected structures in the underlying mantle. Low seismic wave velocity anomalies below the Rio Grande rift have

Magma-compensated crustal thinning in continental rift zones

It is suggested that the expected Moho uplift was compensated by magmatic intrusion into the lower crust, producing the observed high-velocity zone, demonstrating a previously unknown role for magmatism in rifting processes with significant implications for estimation of stretching factors and modelling of sedimentary basins around failed rift structures.

Mantle convection and the recent evolution of the Colorado Plateau and the Rio Grande Rift valley

The Colorado Plateau contains Late Cretaceous marine strata that are at a mean elevation of ~2 km. The timing and amount of uplift since the Cretaceous has generated considerable debate. With the

Geophysical constraints on the crustal structure of the southern Rio Grande rift

Abstract Evidence of geologic activity still occurring in the Rio Grande rift (RGR) includes quaternary faulting, seismicity, and widening at a small rate. We map the crustal thickness and seismic

Imaging continental breakup using teleseismic body waves: The Woodlark Rift, Papua New Guinea

This study images the upper mantle beneath the D'Entrecasteax Islands, Papua New Guinea, providing insight into mantle deformation beneath a highly rifted continent adjacent to propagating spreading

Upper mantle structure beneath the eastern Colorado Plateau and Rio Grande rift revealed by Bouguer gravity, seismic velocities, and xenolith data

The lithospheric architecture of the Colorado Plateau–Rio Grande rift transition zone reflects a narrow corridor of active tectonism and magmatism between the tectonically stable Colorado Plateau and

Active crustal differentiation beneath the Rio Grande Rift

Silicon-rich continental crust is unique to Earth. Partial melting during high- to ultrahigh-temperature metamorphism (700 °C to >900 °C) promotes the long-term stability of this crust because it

Crustal and uppermost mantle structure in the central U.S. encompassing the Midcontinent Rift

Rayleigh wave phase velocities across the western arm of the Midcontinent Rift (MCR) and surrounding regions are mapped by ambient noise (8–40 s) and earthquake tomography (25–80 s) applied to data

Heat-flow anomalies crossing New Mexico along La Ristra seismic profile

Heat-flow data along La Ristra seismic line crossing New Mexico from the Colorado Plateau to the Great Plains suggest that the Jemez Lineament and the Rio Grande rift are high heat-flow geologic



Upper mantle convection beneath the central Rio Grande rift imaged by P and S wave tomography

[1] We present models for upper mantle P and S velocity structure beneath a southwestern United States transect extending from near the center of the Colorado Plateau across the Rio Grande rift to

Chemical and isotopic evidence for lithospheric thinning beneath the Rio Grande rift

Continental rifting disrupts the lithosphere, thermally and chemically modifying the upper mantle and crust beneath a rift. The isotopic and chemical compositions of basaltic rocks associated with

Upwarp of anomalous asthenosphere beneath the Rio Grande rift

Continental rifts are possible analogues of mid-ocean ridges, although major plate tectonic features are less clearly observed1. Current thermal models of mid-ocean ridges2–4 consist of solid

Imaging crust and upper mantle seismic structure in the southwestern United States using teleseismic receiver functions

Rio Grande RIft Seismic TRAnsect (RISTRA) is designed to image and interpret crust and mantle structures beneath the southwestern United States, including the nature of the Colorado Plateau and Rio

Rio Grande rift: An overview

The upper mantle structure of the central Rio Grande rift region from teleseismic P and S wave travel time delays and attenuation

The lithosphere beneath a continental rift should be significantly modified due to extension. To image the lithosphere beneath the Rio Grande rift (RGR), we analyzed teleseismic travel time delays of

Crust and upper mantle shear wave structure of the southwest United States: Implications for rifting and support for high elevation
