In front of the wealth of informations extracted about past environmental and climatic evolutions, for local in regional scales and with an annual in ten-year resolution, it appears very interesting to study endokarstic detritic deposits and to estimate the memory of these natural archives.In this study, we have two aims. Firstly, it's necessary to understand the deposit dynamics sediments by, as well as possible, integrating specificities and constraints induced by end...
