  • Thermoluminescence dating of sediments
  • The AA. describe the principles of TL dating, the various methods used, and contrast TL dating of sediments with the now well-accepted TL dating of pottery. They conclude that while TL dating has the potential to solve many sedimentary problems
  • , more fundamental research needs to be carried out before such dates should be accepted. A set of criteria for acceptable dates is proposed.

  • Thermoluminescence dating of a deep-sea sediment core
  • HUNTLEY, D. J.
  • Comparative uranium-thorium and thermoluminescence dating of weathered Quaternary alluvium in the tropics of Northern Australia
  • The AA. briefly review the TL dating of alluvium and the U/Th dating of pedogenic calcite, iron, and manganese deposits and they report on the application of both techniques to the weathered alluvium of the lower Gilbert River in northern Queensland.
  • PRICE, D. M.
  • The dating of former shorelines in Shorelines and isostasy.
  • This paper is a review of many of the techniques, both relative and absolute, that have been developed to provide information as to the dating of sea-level changes. These techniques include: historical and archaeological evidence, lichenometry
  • , palynology, palaeomagnetism, varves, radiocarbon, uranium series, amino acids, and some other relative dating methods. Field relationships are however paramount and all samples must be placed in a rigorous stratigraphical and geomorphological context before
  • being dated.

  • Radiocarbon dating of pollen by accelerator mass spectrometry
  • In this study, the AA. demonstrate for the first time the radiocarbon dating of pollen concentrate samples by accelerator mass spectrometry. The dates obtained by this method should provide more reliable radiocarbon chronologies for paleo
  • -environmental studies than have been obtainable by bulk sediment dating (eliminate possible sources of contamination).

  • Quality assurance in luminescence dating
  • Dating ; Geochronology ; Methodology ; Palaeo-environment ; Sedimentary ; Thermoluminescence
  • This paper describes a comparatively simple quality assurance method which they have developed in an attempt to assess the accuracy of their own luminescence dates produced by single aliquot dating procedures. It is applicable to all samples and has
  • THOMAS, D., (Editeur scientifique)
  • Luminescence dating applications in geomorphological research
  • Dating ; Glacial features ; Interglacial ; Quaternary ; Research technique ; Sedimentary ; Thermoluminescence
  • This paper provides a summary of the principles of the luminescence (especially optical) dating methods and shows how recent developments (specifically single aliquot dating procedures) have dramatically enhanced the scope and potential

  • Optical dating of Holocene dune sands in the Ferris Dune Field, Wyoming
  • Chronostratigraphy ; Dating ; Dune ; Eolian features ; Holocene ; Quaternary ; Sand ; United States ; Wyoming
  • The primary subject of this paper is a test of optical dating using sand-sized quartz grains from an independently well-dated Holocene dune sequence from the Ferris dune field, Clear Creek, Wyoming. The use of a stratigraphic sequence provides

  • Obsidian-hydration dating of fluvially reworked sediments in the West Yellowstone region, Montana
  • Chronostratigraphy ; Dating ; Fluvial terrace ; Methodology ; Montana ; Quaternary ; Statistics ; United States
  • This study evaluates obsidian-hydration dating in postglacial fluvial terraces cut into an outwash plain near West Yellowstone. Fluvial transport fractures obsidian grains. However, some old hydration rinds may be preserved, thus, a grain may record
  • several fracturing events. Multiple evaluations of source chemistry and hydration rates and multiple rind measurements are required to date fracturing events.

  • 230 Th/U dating of frozen peat, Bol'shoy Lyakhovsky Island (Northern Siberia)
  • Asian part of Russia ; Geochronology ; Palaeo-environment ; Peat ; Periglacial features ; Permafrost ; Pleistocene ; Siberia ; Th/U dating
  • The ice-rich permafrost deposits on the coastal lowland in northeastern Siberia and on the New Siberian Islands often contain layers, lenses, and inclusions of peat that are too old to be dated by AMS. Application of 230 Th/U disequilibrium dating

  • Radiocarbon dates on deglaciation, Cordillera Central, northern Peruvian Andes
  • Three radiocarbon dates along with relative-dating criteria place limits on the deglaciation history of Manachaque Valley. Ice retreated from the late-glacial maximum by at least 12 100 yr B.P. During ice retreat numerous moraines were deposited

  • Subdivision of Late Pleistocene moraines in the Cordillera Blanca, Peru, based on rock-weathering features, soils, and radiocarbon dates
  • Andes ; C14 dating ; Glaciation ; Model ; Moraine ; Palaeogeography ; Peru ; Pleistocene ; Quaternary ; Stratigraphy ; Weathering
  • This paper reports quantitative weathering data and radiocarbon dates from Pleistocene moraines in seven drainages on the west side of the Cordillera Blanca. These are used to test and refine the chronology presented by Clapperton (1972, 1981).
