A modified method from McCrea [McCrea, J.M., 1950. The isotopic chemistry of carbonates and a paleotemperature scale. J. Chem. Phys. 18, 849–857.] has been developed for analyzing carbon and oxygen isotopic compositions of lacustrine calcite in bulk saline lake sediments. A two-level climatic fluctuation model is suggested based on a continuous 200,000-year δ 18 O record of lacustrine calcite...
Uranium-series dating on a 186-m core (DV93-1) drilled from Badwater Basin in Death Valley, California, and on calcareous tufas from nearby strandlines shows that Lake Manly, the lake that periodically flooded Death Valley during the late Pleistocene, experienced large fluctuations in depth and chemistry over the last 200,000 yr. Death Valley has been occupied by a long-standing deep lake, perennial...
