THE KARST OF THE CALANQUES massif - Description of karstic morphology in relation to lithology and tectonic framework; actual hydrography. Sedimentary analysis applied to speleothems (calcitic deposits, hardened silts with rubefaction, upper stalagmitic layers, eolianites). Relations with some recent tectonic mechanisms. Hydrogeology: marine resurgences, subterranean rivers (Port-Miou and Le Bestouan).

The general features of coastal paleokarst in Provence are describes: suspended gallery sections and drain-pipes cut across by fracturations or fault reactivation. The types of deformations and breaking observed are tilting, stalactite fall, extension fault sealing, reactivation and speleothem shearing, coastal wall and karstic cleft collapse as well as network deformation. The influence of structural environment is represented by overlapping strata, coastal faults and crossed-fault systems. Emphasis has been laid on the tectonic inheritance as well as the geodynamic context. To conclude, the importance of provenal-ligurian rifting mechanisms and the transition to faulted and distorted margin is underlined.

The Cosquer Cave is a French palaeolithic painted and engraved cave (27000/ 18500 BP) which is located under the sea, in the urgonian limestones of Cap Morgiou ("Massif des Calanques"; Marseille). The en trance was submerged at the end of the last glacial stage and is presently 37 m under sea level. A synthesis about the Cosquer cave environmental studies is presented here. Structural studies show that cave planimetry is determined by Cap Morgiou fracturations (mainly NW/SE and N/S vertical faults). Through archaeological studies, a concretion breaking period can be dated between 27000 and 18000 BP. Geomorphological study of the continental shelf at the foot of the Cosquer cave area shows fossils shorelines at -36 m, -50/55 m, -90 m, -100 m depth. Radiocarbon datings from shells collected in 100m sediments yielded a date of 13 250 BP. Direct scuba diving observations and submarine clive profiles sketching show several eustatic stand-still levels between -36 m and the sea surface indicating a probable tectonic stability during the last 10000 years.

The paleokarst fillings in the Riou and Frioul archipelagoes, the coastal ranges of MarseiIleveyre (Calanques) Notre Dame de la Garde (the Bay of Marseille) show several examples of various tectonic mechanisms due to compressive stresses. A chronology of the various phases is described: compartment process, overlapping, tilting. These deformations and the several after-episodes observed can be dated between the Lower Eocene and the Upper Pleistocene, but it is still difficult to give a more precise date. The tertiary fillings show the action of local decompression and tilting in some cases. In the detailed study of the karstic lithified deposits two kinds of tectonised sequences are shown in connection with the local tectonics.

The Cosquer Cave is a French Palaeolithic painted and engraved cave (27.000-18.500 BP), which is located under the sea, in the Urgonian limestones of Cap Morgiou (“Massif des Calanques”, Marseille). The entrance was submerged at the end of the Last Glacial Stage and is presently 37 m under sea level. A synthesis about the Cosquer Cave environmental studies is presented here. Structural studies show that caves planimetry is determined by Cap Morgiou jointing (mainly NW-SE and N-S vertical faults). Through archaeological studies, a speleothem breaking period can be dated between 27.000 and 18.000 BP. Geomorphologic study of the continental shelf at the foot of the Cosquer Cave area shows fossil shorelines at -36 m, -50/55 m, -90 m, -100 m depth. Radiocarbon dating from shells collected in -100m sediments yielded a date of 13.250 BP. Direct scuba diving observations and submarine cliff profiles sketching show several eustatic still stand¬ levels between -36m and the current sea surface indicating a probable tectonic stability during the last 10.000 years.


The effect of the Messinian Deep Stage on karst development around the Mediterranean Sea. Examples from Southern France, 2004,

It is difficult to explain the position and behaviour of the main karst springs of southern France without calling on a drop in the water table below those encountered at the lowest levels of Pleistocene glacio-eustatic fluctuations. The principal karst features around the Mediterranean are probably inherited from the Messinian period ('Salinity crisis') when sea level dropped dramatically due to the closing of the Straight of Gibraltar and desiccation of the Mediterranean Sea. Important deep karst systems were formed because the regional ground water dropped and the main valleys were entrenched as canyons. Sea level rise during the Pliocene caused sedimentation in the Messinian canyons and water, under a low hydraulic head, entered the upper cave levels. The powerful submarine spring of Port-Miou is located south of Marseille in a drowned canyon of the Calanques massif. The main water flow comes from a vertical shaft that extends to a depth of more than 147 in bsl. The close shelf margin comprises a submarine karst plateau cut by a deep canyon whose bottom reaches 1,000 in bsl. The canyon ends upstream in a pocket valley without relation to any important continental valley. This canyon was probably excavated by the underground paleoriver of Port-Miou during the Messinian Salinity Crisis. Currently, seawater mixes with karst water at depth. The crisis also affected inland karst aquifers. The famous spring of Fontaine de Vaucluse was explored by a ROV (remote observation vehicle) to a depth of 308 in, 224 m below current sea level. Flutes observed on the wall of the shaft indicate the spring was formerly an air-filled shaft connected to a deep underground river flowing towards a deep valley. Outcroppings and seismic data confirm the presence of deep paleo-valleys filled with Pliocene sediments in the current Rhone and Durance valleys. In the Ardeche, several vauclusian springs may also be related to the Messinian Rhone canyon, located at about 200 in below present sea level. A Pliocene base level rise resulted in horizontal dry cave levels. In the hinterland of Gulf of Lion, the Cevennes karst margin was drained toward the hydrologic window opened by the Messinian erosional surface on the continental shelf

In the south of France, the Cosquer Cave with its famous prehistoric paintings is located in  a karstic area located between Marseilles and Cassis. This emerged and submerged karst is  typical ofkarstic coasts submerged after the Late-Glacial Maximum. Ail the forms observed  in the hinterland can be observed directly by scuba divers and indirectly on bathymetrie  charts: lapiaz, karstic archs, sinkholes, uvala and polje. The emerged and submerged landscapes  are mainly the heritage of specifie lithological conditions (Urgonian limestones) and  tectonic conditions (vertical faulting network leading to coastal eollapse in theMediterranean  Sea). üther elements of this submerged Iandscape are given by the traces of the last sea  level rise (palaeo-shorelines and erosion platforms and notehes). AIl the area between  Marseilles and La Ciotat is now established as the Calanques National Park, inc1uding the  Cosquer Cave with its upper Palaeolithic rock art paintings, which adds an international  archaeological interest to this exceptional natural area
