Description :
Seven dates have been produced, using the 230Th/234U dating method on six samples of speleothems collected in a cave, recently discovered in Gaspésie. Ages obtained range between 102000 and 223000 years B. P. The absence of redissolution traces in the calcite of the samples suggest that the cave was dewatered for more than 200000 years. This very old cave which seems to have survived more than one glacial period also contains a noticeable variety and quantity of bones, some of which covered with calcite deposits.
