Abstract:
Granulométric analysis, petrography and micromorphology of the stratigraphic unit C III, deposited during the upper Middle Pleistocene in the Lazaret cave at Nice, allows to characterise the origin of the sedimentary layers and the process of deposition and the post-sedimentary transformations. This unit is a slope colluvium, derived from quaternary formations surrounding the cave and very rich in fine particles, deposited in several sheets at the entrance of the cave, it got further spread through runoff. In the middle of the unit C III, coarse components increase due to desquamation and falling in from the wall of the cave composed of a Miocene conglomerate and Jurassic limestone. After deposition, this colluvium was subjected to sorting of the fine particles (silts and clays) towards the cave centre and back and secondary carbonation crusts calcareous beds. These data are confirmed by the results of paleontologic and palynologic analyses regarding the climatic conditions prevailing during the deposition of the unit C III.
