NEW RESEARCHES ON THE MEDITERRANEAN KARSTS - More precise measurements are now being used to establish the rates of which limestone dissolves and the corrosion processes (regular hydrochemical measurements, Iv. GAMS limestone tablets method). In the study of the morphological evolution, the role of the quaternary paleoclimate is estimated by dating on the speleothems and the meaning of the outer carbonate formations has been revealed. Bauxite and terra rossa and various weatings make it possible to specify the pre-quaternary evolution and the origin of paleokarsts. Thanks to new methods, the influence of neotectonic is taken into account, especially the effects of the rise of numerous massifs to which we can add the variations in the sea level with coastal limestone formations. By way of conclusions we must stress the importance of studying karstical surroundings and the problems of applied karstology studies.
WESTERN ALPS PALEOKARSTS FROM TRIASSIC TO EOCENE - In western Alps, before complete emersion during the Oligocene and Miocene, the marine sedimentation has been locally interrupted by three important continental phases: 1/ during Early Jurassic, in "briançonnais" domain; 2/during middle Cretaceous, in Provence area; 3/ during early Tertiary, in subalpine range and Jura. These locally and temporary regression are the consequence of tectonic activities in relation to the movements of eurasiatic and italo-african plates, which are at the edge of the alpine oceanic basin (Tethys). After an abstract on the tectonic and sedimentological history of western Alps, a description is given of continental formations (bauxites, fire-clay, clay with flints, siderolitic formations, white and ochrous sands, siliceous and ferruginous crusts) and karst phenomena elaborated during these regressions.
NEOGENE PALEOKARSTS AND PALEO-GEOMORPHOLOGY IN THE WESTERN ALPS, JURA AND PROVENCE - This text is an attempt to confront our knowledge about the karsts and the problems of landscape evolution (tectonics, paleo-climates, sea level changes). Three periods had been studied: 1/ Early and Middle Miocene, with the development of chemical erosional surfaces and a prevailing sub-superficial karstic solution; 2/ the revolution of the Upper Miocene ("Rhodanian" tectonical phase and the salinity crisis of the Messinian), that caused the deepening of the karstic systems; 3/ the Plio-Villafranchian phase, favoured the production of terra-rossa and the evolution of the karstic caves, except during some dry periods during the Villafranchian.
Society Cliffs Formation; episodes of karstification since its deposition. During the first karst episode an evaporite solution-collapse breccia formed ubiquitously on the western Borden Peninsula. During the second karst episode a holokarst developed and an integrated cave system was formed. The caves subsequently were filled with sulfides and carbonate minerals; several interesting sedimentary structures exist in the zinc-lead sulfide deposits. The ore fluid and contained metals are postulated to have been derived during a late-stage dewatering of the black shale that underlies the Society Cliffs Formation. Sulfide deposition may have been caused by chemical reduction of sulfate that existed in the ore fluid when the fluid entered hydrocarbon-filled caves. During the third and fourth episodes of karstification, only merokarst developed in the Society Cliffs Formation. Karst effects which formed during these episodes include oxidized sulfide deposits and surface solution corridors.--Modified journal abstract
