  • Hydrologic variation during the last 170,000 years in the southern hemisphere tropics of South America

    Open AccessSherilyn C Fritz, Paul A Baker et al.ARTICLEQuaternary Research2004

    Despite the hypothesized importance of the tropics in the global climate system, few tropical paleoclimatic records extend to periods earlier than the last glacial maximum (LGM), about 20,000 years before present. We present a well-dated 170,000-year time series of hydrologic variation from the southern hemisphere tropics of South America that extends from modern times through most of the penultimate glacial period. Alternating mud and salt units…

  • Climate Variability in East-Central California during the Past 1000 Years Reflected by High-Resolution Geochemical and Isotopic Records from Owens Lake Sediments

    Open AccessHong-Chun Li, James L Bischoff et al.ARTICLEQuaternary Research2000

    Core OL-97A, retrieved from the depocenter of Owens Lake, represents a depositional history spanning the past 1000 yr. Among the 17 elements analyzed in the acid-leachable fractions of 315 salt-free samples (at ∼3 yr/sample), Mg and Li, which come chiefly from authigenic Mg-hydroxy-silicates, were found to have concentration variations reflecting lake salinity and climatic changes during the past. A total of 231 isotopic measurements on carbonate…

  • A 200,000-Year Record of Change in Oxygen Isotope Composition of Sulfate in a Saline Sediment Core, Death Valley, California

    Open AccessWenbo Yang, H Roy Krouse et al.ARTICLEQuaternary Research1999

    δ 18 O values of sulfate minerals from a 186-m core (past 200,000 years) in Death Valley varied from +9 to +23‰ (V-SMOW). Sulfates that accumulated in the past ephemeral saline lake, salt pans, and mud flats have relatively low δ 18 O values similar to those of present-day local inflows. Sulfates that accumulated during two perennial lake intervals, however, have higher δ 18 O values, reflecting changes in temperature, lake water levels, and/or s…

  • U-Series Chronology of Lacustrine Deposits in Death Valley, California

    Open AccessTeh-Lung Ku, Shangde Luo et al.ARTICLEQuaternary Research1998

    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 shallow saline lakes, and a desiccated salt pan…

  • Soil-Carbonate Genesis in the Pinacate Volcanic Field, Northwestern Sonora, Mexico

    Open AccessJanet L Slate, William B Bull et al.ARTICLEQuaternary Research1991

    Uranium-series methods were used to date and evaluate pedogenic CaCO 3 genesis in the Pinacate volcanic field, northwestern Sonora, Mexico. Soils are developed in eolian deposits on lava flows. 230 Th/ 234 U dates of pedogenic carbonate are mininum soil ages because of (1) the time needed to yield clasts from flows and to accrete enough carbonate to sample, (2) subsequent additions of uranium, and (3) continued solution and reprecipitation of car…

  • U-Series Dating of Last Interglacial High Sea Stands

    Open AccessTeh-Lung Ku, Μ Ivanovich et al.ARTICLEQuaternary Research1990

    U-series chronologies of the emerged coral limestone terraces on Barbados, West Indies, together with those of the terraces from New Guinea, have formed the basis for most late Pleistocene eustatic models. The so-called “Barbados sea level model” has been challenged in recent years, however. A major issue is whether during oxygen isotope stage 5e, when Rendezvous Hill reef complex on Barbados Island formed, the sea rose above the present position…

  • Holocene Sea-Level Changes in Palau, West Caroline Islands

    Open AccessWilliam Heyden Easton, Teh-Lung Ku et al.ARTICLEQuaternary Research1980

    14 C ages supplemented by 230 Th/ 234 U determinations have been obtained for calcareous deposits on Koror, Babelthuap, Auluptagel, and Adorius Islands in the Palau Group, West Caroline Islands. Test borings for a bridge between Koror and Babelthuap reveal shoreface terraces consisting largely of bioclastic sand, but resembling fringing reefs. The base of the shoreface terraces dates to between 7000 and 8000 14 C yr B.P. and the upper surfaces ar…

  • A Method for Quantitative Evaluation of Carbonate Dissolution in Deep-Sea Sediments and its Application to Paleoceanographic Reconstruction

    Open AccessTeh-Lung Ku, Teh‐Lung Ku et al.ARTICLEQuaternary Research1978

    A method is proposed by which the degree of attrition of the tests of certain foraminifera species, such as Globorotalia menardii and Globorotalia tumida , is used to “scale” the amount of CaCO 3 that has been dissolved from sediment. The scale is calibrated experimentally in the laboratory. The method has been applied to three calcareous cores from the Pacific and the Indian Oceans. It is shown that the original CaCO 3 contents in these cores we…
