Processes and rates of arc crust growth and differentiation in the Southern Sierra Nevada crustal section
… the exposed crustal section in the southernmost Sierra Nevada Batholith, California. This section exposes plutons that were emplaced at pressures ranging from 3-10 kbars, as well as metamorphic wall rocks. Chapters 1 and 2 represent focused studies of the Bear Valley Intrusive Suite (BVIS), the …

Testing the Utility of S Receiver Function Analysis For Mapping Seismic Discontinuities In the Sierran Lithosphere
… lithospheric delamination of the Cretaceous Sierra Nevada batholith is responsible for the disappearance of its dense residual eclogitic root (Zandt et al., 2004). Lithospheric delamination may be an effective, widely occurring mechanism for both lithospheric thinning and the production of …

Seismic imaging of the lithosphere-asthenosphere boundary with a dense broadband array in central California
… the Monterey microplate (Wang et al., 2013) and Sierra Nevada batholith (Ducea & Saleeby, 1998). Results include 918 binned receiver functions that were made using multi-channel spectral deconvolution and an array-based spectral source estimation on the event data from an 18- month deployment of …

Paleogeography of Western North America: Insights from Detrital Zircon U-Pb Geochronology and Hf Isotope Geochemistry
… North American Cordilleran arc: Coast Mountains batholith, North Cascades Range, Idaho batholith, Sierra Nevada batholith, Transverse Ranges, Peninsular Ranges, Sierra Madre Occidental, and the Porphyry Copper Province. Identifying changes in sediment provenance from Sevier thin-skinned thrusting …

Emplacement of the Santa Rita Flat pluton and kinematic analysis of cross cutting shear zones, eastern California
… with geometrically similar shear zones in the Sierra Nevada batholith to the west, suggests that the SRSS probably nucleated from a regional stress field in Cretaceous times (~90-78 Ma). Strain is heterogeneous within the shear zones, with local development of protomylonite, mylonite, …

Mineral-Scale Sr Isotopic Study of Plagioclase in the Mafic Dikes of the North American Wall and the Diorite of the Rockslides, Yosemite Valley, California.
The North American Wall mafic dikes and the diorite of the Rockslides mafic complex in the intrusive suite of Yosemite Valley show evidence of mixing with their host granites as well as with earlier components. Whole rock major element variation diagrams indicate the mafic rocks mixed with a more …
