Provenance of Eocene river sediments from the central northern Sierra Nevada and implications for paleotopography
[1] Geochronology of fluvial deposits can be used to characterize provenance, the paleotopography of sediment source regions, and the development of regional drainage systems. We present U‐Pb and (U‐Th)/He ages of detrital zircon grains from Eocene gravels preserved in several paleoriver systems along the western flank of the central and northern Sierra Nevada. These ages allow us to trace the ...
متن کاملHypsometry of Glaciated Landscapes
Hypsometry (frequency distribution of elevations) is often used to characterize landscape morphology, traditionally in the context of the degree of fluvial dissection. Recently, the hypsometry of glaciated regions has been used to infer how rates of glacial erosion compare with tectonic uplift rates. However, many factors other than tectonics can also exert a major influence on the hypsometry o...
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 کاملA Miocene to Pleistocene climate and elevation record of the Sierra Nevada (California).
Orographic precipitation of Pacific-sourced moisture creates a rain shadow across the central part of the Sierra Nevada (California) that contrasts with the southern part of the range, where seasonal monsoonal precipitation sourced to the south obscures this rain shadow effect. Orographic rainout systematically lowers the hydrogen isotope composition of precipitation (deltaD(ppt)) and therefore...
متن کاملInfluence of lithology on hillslope morphology and response to tectonic forcing in the northern Sierra Nevada of California
[1] Many geomorphic studies assume that bedrock geology is not a first-order control on landscape form in order to isolate drivers of geomorphic change (e.g., climate or tectonics). Yet underlying geology may influence the efficacy of soil production and sediment transport on hillslopes. We performed quantitative analysis of LiDAR digital terrain models to examine the topographic form of hillsl...
