Cosmogenic Nuclide Burial Isochron Data for the Central City Gravel, Malta Gravel, and Lava Creek B Ash Locations: Classic Locations of Early to Middle Pleistocene Deposits, South Platte and Arkansas Rivers, Central Colorado, USA

Description

This data release includes Al-26/Be-10 cosmogenic nuclide concentrations and burial isochron ages for three locations in central Colorado, USA, with preferred burial ages ranging from ~2 Ma to 600 ka, that provide constraints on geologic mapping and chronostratigraphic correlations of Pleistocene Colorado Rocky Mountain (CRM)-Great Plains deposits. This new dataset helps to validate original identification and characterization of the deposits by renowned work of early to late 20th century geologists. In addition, this dataset is critical for any models of geomorphic development of modern Colorado Rocky Mountain (CRM)-Great Plains depositional systems, including analyses of regional relationships involving the Malta Gravel, Nussbaum [...]
