Intrt des sdiments dtritiques endokarstiques en tant quarchive naturelle ? Discussion autour des dpts lacustres souterrains (Grottes de Choranche - Vercors), 2006, Perroux Annesophie
Interest of endokarstic detritic sediments as a natural archive? Discussion on underground lacustrine deposits (Choranche Caves Vercors) - Among the various natural environmental archives, the underground detritic deposits remained hitherto forgotten, in particular for high resolution analyses and treatments. Through the study of the sedimentary accumulation of the Cathedral Lake (Choranche Caves, Vercors), this paper shows the potential of information which these deposits contain. Sedimentary cores were sampled in the lake, various data are measured (granulometry, spectrocolorimetry, magnetic susceptibility and gray level imagery), then submitted to statistical processing (PCA, Passega images...) and signal treatment (wavelet decomposition). The stratigraphy of charcoal fragments trapped in the sediment and dated by the 14C method, does not appear sufficiently coherent to propose a satisfying age-depth model. Only some dates make it possible to suppose that the sedimentary filling of the lake covers at least the 4000 last years, with an average rate of sedimentation estimated at 1.87mm/yr. The other results of this work make it possible to understand transport and deposition dynamics of the sedimentary particles in an endokarstic lake, in particular with regard to flooding episodes. The Cathedral lake has a binary functioning, with mainly a fine sedimentation (decantation), punctually stopped by flooding episodes, which on their turn have two different dynamics (brutal or progressive phenomena in sedimentation). Lastly, the study of various signals highlights a great number of sedimentation control factors; these factors seem to act mainly on small time scales (more than 80 % of the granulometric signal variation are linked to phenomena with a period inferior to 40 years, according to the chronological framework supposed in the first assumption). This work carried in Choranche shows that endokarstic detritic sediments contain high resolution archives of the environmental evolutions. Subject to a chronological positioning more precise than the one we have today, paleoenvironmental interpretations and reconstitutions will make it possible to go further in their reading.
