Isotopic Evidence on the Structure and Origin of Subcontinental Lithospheric Mantle in Southern Nevada
The trace element and Nd, Sr, and Pb isotopic compositions of extension-related late Cenozoic basalts in southern Nevada were determined in order to constrain models for the tectonic evolution of the subcrustal mantle in the southern Great Basin since 10 Ma. Basalts in southern Nevada between latitudes 36øN and 37øN have low ENd (--8 to -10), high A8/4 (+70 to + 107) and A7/4 (+8 to + 12), high...
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 کاملConcordant molecular and phenotypic data delineate new taxonomy and conservation priorities for the endangered mountain yellow-legged frog
The mountain yellow-legged frog Rana muscosa sensu lato, once abundant in the Sierra Nevada of California and Nevada, and the disjunct Transverse Ranges of southern California, has declined precipitously throughout its range, even though most of its habitat is protected. The species is now extinct in Nevada and reduced to tiny remnants in southern California, where as a distinct population segm...
متن کاملAssessing ecosystem threats from global and regional change: hierarchical modeling of risk to sagebrush ecosystems from climate change, land use and invasive species in Nevada, USA
Global change poses significant challenges for ecosystem conservation. At regional scales, climate change may lead to extensive shifts in species distributions and widespread extirpations or extinctions. At landscape scales, land use and invasive species disrupt ecosystem function and reduce species richness. However, a lack of spatially explicit models of risk to ecosystems makes it difficult ...
متن کاملSupracrustal input to magmas in the deep crust of Sierra Nevada batholith: Evidence from high-dO zircon
Oxygen isotope ratios of zircon (Zc) from intrusives exposed in the Tehachapi Mountains, southern California, reveal large inputs of high-dO supracrustal contaminant into gabbroic and tonalitic magmas deep (N30 km) in the Cretaceous Sierra Nevada batholith. High dO(Zc) values (7.8F0.7x) predominate in the deep parts of the batholith, but lower values (6.1F0.9x) occur in shallower parts. This in...
