Numic Expansion in the Southern Sierra Nevada
Recent research indicates that late prehistoric Numic expansion onto the western slope of the southern Sierra Nevada was facilitated by a competitive edge held by migrating groups, mainly Great Basinderived settlement and subsistence behaviors finetuned to the uncertainties of living in Little Ice Age mountain environments. But ethnographic, linguistic, and archaeological evidence also sugges...
متن کاملTopography of the Southern Sierra Nevada
SEPTEMBER 2005, GSA TODAY ABSTRACT The paleoelevation of the Sierra Nevada, California, is important to our understanding of the Cenozoic geodynamic evolution of the North America–Pacific plate boundary, and the current debate is fueled by data that argue for conflicting elevation histories. The non-equilibrium or transient landscape of the Sierra Nevada contains information about both past and...
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 کاملBlue Oak Regeneration in Southern Sierra Nevada Foothills1
A survey of blue oak stands in four southern Sierra areas indicated there was a substantial number of seedlings and mature trees, but there were considerably fewer trees in the sapling and pole size class. These differences prompted a long-term survival study. After 6 years, 68.5 percent of the trees were still present and had grown 0.02 inches. A study of aging seedlings showed that the percen...
متن کاملFoundering 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...
