Foundering lithosphere imaged beneath the southern Sierra Nevada, California, USA.
Seismic tomography reveals garnet-rich crust and mantle lithosphere descending into the upper mantle beneath the southeastern Sierra Nevada. The descending lithosphere consists of two layers: an iron-rich eclogite above a magnesium-rich garnet peridotite. These results place descending eclogite above and east of high P wave speed material previously imaged beneath the southern Great Valley, sug...
متن کاملMantle instability beneath the Sierra Nevada Mountains in California and Death Valley extension
The Southern Sierra Nevada mountain range rapidly uplifted at ≈3.5 Ma simultaneously with a pulse of basaltic volcanism. Xenoliths recovered from volcanics indicate that the range lost a dense crustal root after the Miocene. The vertical motions and removal of the root have been linked to a fast seismic velocity anomaly that extends ≈200 km into the mantle but is offset to the west of the range...
متن کاملChronology of pluton emplacement and regional deformation in the southern Sierra Nevada batholith, California
Cretaceous plutonic rocks of the southern Sierra Nevada batholith between latitudes 35.5°N and 36°N lie in a strategic position that physically links shallow, subvolcanic levels of the batholith to lower-crustal (~35 km deep) batholithic rocks. This region preserves an oblique crustal section through the southern Sierra Nevada batholith. Prior studies have produced large U/Pb zircon data sets f...
متن کاملGlaciations of the Sierra Nevada, California, USA
The Sierra Nevada is a c. 4000 m range of mountains paralle1 to the North American Pacific Coast that was repeatedly glaciated during the climatic fluchrations of the Quatemary. The glacial record on the eastem side of the range includes eight named Pleistocene glaciations and stadials: McGee, Sherwin, Casa Diablo, Mono Basin, Tahoe, Tenaya, Tioga and Recess Peak, as well as the Neoglacial Matt...
متن کاملDiscussing epigenetics in Southern California
With the goal of discussing how epigenetic control and chromatin remodeling contribute to the various processes that lead to cellular plasticity and disease, this symposium marks the collaboration between the Institut National de la Santé et de la Recherche Médicale (INSERM) in France and the University of California, Irvine (UCI). Organized by Paolo Sassone-Corsi (UCI) and held at the Beckman ...
