Morphologie et remplissage des dolines du Causse de Martel d’après les observations réalisées au cours du diagnostic archéologique de l’aérodrome de Brive-Souillac (Corrèze et Lot)
Abstract:
Doline morphology and filling in the Causse of Martel based on the observations realized during the archaeological diagnosis of the Brive-Souillac airfield (Corrèze and Lot, France) - An operation of archaeological diagnosis was led by the INRAP (national institute for preventive archaeological researches) on the Causse de Martel. On this occasion, 610 trenches with bulldozers were done, mainly localized in the bottom of dolines. The morphology of the depressions presents most often a pronounced asymmetry. We observe a gently dipping slope underlain by sandy alterites. On the opposite side, a steep corrosion rim developed in bathonian limestones. The sections show an accumulation of several meters of different sediments. At the base, we find periglacial deposits (stratified scree and yellow silt) which fossilized some archaeological remains of the middle Paleolithic. Just above an erosional unconformity, brown clays with calcareous gravel are found. Thanks to the presence of archaeological material, we date the emplacement of this level to be between the Protohistory and the medieval age. Finally, one or two meters of modern agricultural colluviums end the sequence. These observations put in evidence at least two main periods of infilling of these dolines. They correspond to two major phases of hillside imbalance. The first one has a climatic origin (Periglacial) and the second a human origin (clearings and agriculture). These accumulations are separated from the underlying deposits by distinct erosion surfaces, which can be linked to a reactivation of the karstic undercapture and the erosion of a part of the filling. This functioning corresponds to periods during which the colluviums are less abundant, indicating a certain stability of hillsides. Finally, the morphology of the rock layers and the geometry of the deposits show that the karstic landscape, which was clearly more accentuated before the Periglacial and even before Protohistory, underwent an important filling. Today, the dolines are partially filled and show with a flat bottom.
