New apatite (U-Th)/He ages from the central Sierra Nevada, California, place limits on the morphology and evolution of longitudinal profiles of major transverse river drainages developed in the Late Cretaceous....

New thermodynamic data are presented for the Gibbs energy of formation of dolomite (CaMg(CO3)2(s)). Using electrochemical cells, we find Δ*Gf°[CaMg(CO3)2(s))] equal to −2147.82 kJ · mol−1. The performance of lattice...

There were three negative seawater strontium-isotope excursions (shifts to lower 87Sr/86Sr values) during the Jurassic and Cretaceous that were of relatively short duration (5–13 my) and showed a relatively quick...

Early to mid-Cretaceous dextral strike-slip faulting, involving up to 400 km displacement, has been documented in the southern Sierra Nevada of California.In western Idaho, the Salmon River suture juxtaposes unrelated...

Revision of the GEOCARB model (Berner, 1991, 1994) for paleolevels of atmospheric CO2, has been made with emphasis on factors affecting CO2 uptake by continental weathering. This includes: (1) new...
