The Mexican orogen is the expression in Mexico of the Cordilleran orogenic system. The
orogen extends the length of Mexico, a distance of 2000 km from the state of Sonora in the …

Sedimentary basins of the broadly defined Laramide province, which includes the Rocky
Mountain region from Montana south to New Mexico, the Colorado Plateau, and the …

The origin and tectonic setting of the Mesoproterozoic (1.50–1.34 Ga) granite–rhyolite
Provinces of the midcontinent region of the United States, and the coeval A-type granite …

The upper mantle of North America has been well studied using various seismic methods.
Here we investigate the density structure of the North American (NA) upper mantle based on …

Abstract The Ancestral Rocky Mountains system consists of a series of basement-cored
uplifts and associated sedimentary basins that formed in southwestern Laurentia during …

Tectonostratigraphic assemblages record phases of basin history during which the
fundamental controls of tectonic setting, subsidence style, and basin geometry are relatively …

Detrital zircon and igneous zircon U-Pb ages are reported from Proterozoic metamorphic
rocks in northern New Mexico. These data give new insight into the provenance and …

New U-Pb zircon ages, geochemistry, and Nd isotopic data are presented from three
localities in the Paleoproterozoic Mazatzal province of southern New Mexico, United States …

Late Mesoproterozoic sedimentary sequences in southwest Laurentia range in age from
1340 to 1035 Ma and record regionally extensive intracratonic sedimentation before and …

New field studies combined with U-Pb zircon geochronology constrain the ages of
deposition and sedimentary provenance of Paleoproterozoic quartzite successions exposed …
