Nogal Canyon caldera, southern San Mateo Mountains, Socorro County, New Mexico; A progress report
V. T. McLemore The Nogal Canyon caldera is the southernmost caldera that formed the San Mateo Mountains. Mt. Withington (27.4 Ma) and Bear Trap Canyon (24.4 Ma) calderas are north of the Nogal Canyon caldera.
Late Cretaceous U-Pb tuff ages from the Laramide Skunk Ranch formation, Little Hatchet Mountains, southwestern New Mexico
G. R. Jennings and T. F. Lawton New LA-ICP-MS U-Pb ages on zircon crystals from airfall tuff beds within the Skunk Ranch Formation, a Laramide synorogenic unit exposed in the Little Hatchet Mountains, southwestern New
Calcite-filled travertine used to constrain the timing and orientation of Quaternary extension along the western margin of the Rio Grande rift, central New Mexico
J. W. Ricketts, A. Priewisch, M. Kolmaznik and K. E. Karlstrom Large-volume travertine deposits in the Lucero Uplift provide an excellent opportunity to understand and quantify Quaternary extension along the western boundary of the Rio
Uranium-series dating of travertine from Soda Dam, New Mexico: Constructing a history of deposition, with implications for landscape evolution, paleohydrology, and paleoclimatology
A. J. Tafoya, L. J. Crossey, K. E. Karlstrom, V. Polyak, Y. Asmerom and C. Cox High precision uranium-series geochronology at Soda Dam, New Mexico provides a record of paleohydrology and incision history for the
Large-volume Quaternary travertine deposits in the Rio Grande rift and Jemez lineament, New Mexico and Arizona: Implications for paleoclimate, landscape evolution, and neotectonics
A. Priewisch, L. J. Crossey, E. Embid, K. E. Karlstrom, V. Polyak, Y. Asmerom, J. Ricketts and A. Nereson New Mexico and Arizona host several large-volume (0.2-0.9 km3) travertine deposits with surface areas of 10
