Kauai, the Petrified Forest, Costa Rica, and more: New GSA Bulletin articles now online
Date:2/26/2013

ients, with mean annual precipitation ranging from 0.5 to 9.5 m. Eroded rock volumes from basins across Kauai indicate that basin-averaged erosion rates over the past several million years vary by a factor of 40 across the island and increase with modern mean annual precipitation. In the Hanalei basin of Kauai, estimates of sediment fluxes and solute fluxes imply that modern erosion rates are no more than 2.3 plus or minus 0.6 times faster than erosion rates over the past few thousand years, as determined by new measurements of helium-3 in olivines in stream sediment. To the extent that modern precipitation patterns resemble long-term precipitation patterns, these measurements provide new support for a link between precipitation rates and long-term basin-averaged erosion rates.


Sedimentological constraints on the evolution of the Cordilleran arc: New insights from the Sonsela Member, Upper Triassic Chinle Formation, Petrified Forest National Park (Arizona, USA)
Evan R. Howell, Noble Energy, 1625 Broadway, Suite 2200, Denver, CO 80202, USA; and Ronald C. Blakey. Posted online 22 Feb. 2013; http://dx.doi.org/10.1130/B30714.1.

The Sonsela Member of the Upper Triassic Chinle Formation in Petrified Forest National Park, Arizona, USA, forms a distinctive part of an extensive ancient river system that once flowed, at least in part, from a major volcanic arc bordering the western margin of North America (Cordilleran magmatic arc). The Sonsela Member is characterized as a relatively coarse-grained unit compared to other mudstone-dominated members of the Chinle Formation, and is therefore thought to reflect a unique period in the evolution of the basin. Modern exposures of the Cordilleran arc are poorly preserved, the result of subsequent tectonic deformation, erosion, and sedimentation in western North America since the Late Triassic.
