  • Postglacial fracturing in the Cantabrian Cordillera (NW Spain)

  • In this paper, the AA. propose that major climatic change from glacial to postglacial conditions occurred as a single step centered on 14,000 yr B.P. In contrast, Heusser (1987) proposed that final warming to postglacial conditions did not occur

  • morphology. They were produced in a periglacial zone of the older Rio Blanco glaciation. The present glacial and cryonival systems were affected by the Punrun glaciation phase and postglacial climatic conditions. The valley bottoms and lowermost parts
  • of the slopes were transformed by mass movements and mud/debris flows in the postglacial period.

  • 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

  • formation in the Richmond River Valley did not commence until after the initial postglacial transgression. Synchronous changes in sea level and rainforest development suggest that there was no significant time lag between climate and sea-level change.
