Cenozoic Exhumation Across the High Plains of Southeastern Colorado from (U-Th)/He Thermochronology

Autor: Sabrina J. Kainz, Lon D. Abbott, Rebecca M. Flowers, Aidan Olsson, Skye Fernandez, James R. Metcalf

Publikováno v: Lithosphere, Vol 2023, Iss Special 14 (2024)

Colorado’s High Plains stand at anomalously high elevations (~1300–2100 m) for their continental interior setting, but when and why this region became elevated is poorly understood. The Cenozoic history of the High Plains is also likely linked wi

Post-Laramide, Eocene epeirogeny in central Colorado—The result of a mantle drip?

Autor: Lon D. Abbott, Rebecca M. Flowers, James Metcalf, Sarah Falkowski, Fatima Niazy

Publikováno v: Geosphere. 18:1223-1246

The Southern Rocky Mountains first rose during the Laramide Orogeny (ca. 75–45 Ma), but today's mountains and adjacent Great Plains owe their current height to later epeirogenic surface uplift. When and why epeirogeny affected the region are contro

The Gothic Dome: Kilometer-scale Miocene Exhumation in Colorado’s Elk and West Elk Mountains

Autor: Robert Kelleher, Rebecca M. Flowers, Noah McCorkel, Coleman Hiett, Edward Riccio, Hector Camm, Lon D. Abbott, Mitchell Ramba, James R. Metcalf

The Colorado Rockies were initially raised during the Laramide Orogeny ca. 70-45 Ma. But consensus exists that the range experienced a second, post-Laramide episode of surface uplift; the timing an...

Effect of rock strength on exhumation and the thermochronologic record: The south-central Colorado example

Autor: Sabrina Kainz, Lon D. Abbott, James R. Metcalf, Rebecca M. Flowers

Past work has used the Southern Rocky Mountains (SRM) in the U.S. state of Colorado to illustrate the important role that rock strength plays in the histories recorded by the apatite fission track (AFT) and apatite (U-Th)/He (AHe) low-temperature the

Rates of river incision and scarp retreat in eastern and central Grand Canyon over the past half million years: Evidence for passage of a transient knickzone

Autor: Lon D. Abbott, Chance Traub, Craig C. Lundstrom

Publikováno v: Geosphere. 11:638-659

Crow et al. (2014) and Abbott et al. (2015) were the first studies to use river terrace age data to extend the incision record for eastern and central Grand Canyon beyond ca. 400 ka. An accurate understanding of Grand Canyon’s long-term incision hi
