  • The AA. consider the palaeoclimatic implications of speleothem growth frequency in the British Iles during the last 220 000 yr, and interpret the results with respect to the recognized stages and substages of the British Quaternary. The speleothem
  • growth frequency curve presented here records nine periods of enhanced speleothem growth between 140 000 and 20 000 yr B.P. which correspond to warmer periods with increased growth of vegetation.
Cinétique du concrétionnement dans quelques grottes belges: apport des datations 14C et 230 Th/234U. (Kinetics of speleothems growth in some Belgian caves as inferred from 14C and U-series dating)

  • Over 60 14C analyses on speleothems. First results of 230 Th/234U dating indicate a period of speleothem growth between 85 and 130 ka BP. A slowdown or maybe an interruption of the calcite deposition occurred during the cold phases of the Quaternary
  • which are in the range of the applied methods (about 0-30 ka BP and 5-350 ka BP for 14C dating and 5-350 ka BP for 230Th/234U dating). Speleothems developed in Holocene and Eemian show vertical growth rates from 0,2 to 0,3 cm. 100 Years I. (LW).
Rates of cave and landform development in the Yorkshire dales from speleothem age data
  • Rates of cave and landform development in the Yorkshire dales from speleothem age data
  • Uranium-series ages have been obtained for 87 speleothems collected from nine major cave systems in the Craven district of northern England. Large systems such as Ease Gill Caverns, the West Kingsdale caves, and Gaping Gill-Ingleborough Cave, which

Paleoclimatic and geomorphic implications of 230/234 dates on speleothems of Britain
  • Paleoclimatic and geomorphic implications of 230/234 dates on speleothems of Britain
Electron Spin Resonance (ESR) dating of hominid-bearing deposits in the Caverna delle Fate, Ligure, Italy
  • The purpose of this study is to establish the chronostratigraphy of the deposits in relation to the human remains. The samples used are speleothems. They belong to two stalagmitic floor which are interstratified in the Mousterian layers.
Paleoclimate deduced from a multidisciplinary study of a half-million-year-old stalagmite from Rana, northern Norway
  • . The AA. also present evidence for the hypothesis that speleothem growth is halted by the proximity of glacier ice.
Open and filled karst features on the Cayman Islands : implications for the recognition of paleokarst
