Dating of the devils hole calcite vein.

et al. (2) present a long, continuous, highresolution climate record extracted from a calcite vein in Devils Hole, Nevada. If their dating is accurate, the record appears to contradict the Milankovitch hypothesis (3). Dating of subsamples of the vein was done with the use of well-established principles of 230Th dating (4) and with recently developed techniques for precise measurement of 230Th a...

First evidence of accumulation of mega boulders on the Mediterranean rocky coast of Provence (southern France)

An accumulation of boulders was recently discovered along the rocky coast of the Gulf of Fos located in Provence, in an area exposed to a south-westerly wave regime. The coast around this locality forms the western extremity of the calcareous Nerthe range between Marseille and the Rhône Delta. Several mega blocks are scattered to a distance of 30 m behind the coast line. The largest block (33.5...
