Abstract
Radiochronological and mineralogical studies of the stagmitic floor '' Ensemble E'' of the Lazaret cave at Nice revealed that its formation h as been continuous during the climatic period corresponding to ''stage 5''. In addition, biochemical analyses of this floor showed that the crystals behave as a closed system with respect to organic compounds ( sterols). Oxygen isotopic compositions have registered variations whic h are qualitatively in agreement with those ascribed to stage 5. There fore, these oxygen isotopic variations may be used as an independent g eochemical chronometer.
