Un exemple de karst haut-alpin : le Dsert de Plat (Haute-Savoie), 1984, Maire, R.
AN EXAMPLE OF HIGH ALPINE KARST: THE DSERT DE PLAT (HAUTE-SAVOIE) - Situated in the French Northern Alps between 1600m and 2800m elevation, the Dsert de Plat is characterised by a wet, cold and very snowy climate (P = 2400-2800 mm/year). We observe several morphoclimatic levels: the upper mountain karst (1500-1700m), the subalpine karst (1700-1950m), the alpine karst (1950 - 2600m) and the proglacial karst (well developed in the Haut-Giffre massif. Glacio-karstic landforms like cirque-dolines and pavements (Schichttreppenkarst) are inherited from the quaternary glaciations. The deep karst underlines the part of quaternary climatic sequence with complex drainage and fillings. Now, the karstic flow is a nival type (maximum during the spring and summer minimum) but the hydrochemical cycles are opposite (spring minimum). Nevertheless, because of a very abundant underground discharge during hot season (80%), the exported limestone reaches 75% of annual amount. The specific dissolution is strong (104 mm/ky), but it does not reach the optimum of forest mountain karst, like Vercors (120-170mm/ky).

Les cavits d'Afrique du Sud, 1985, Martini, J.
Caves of South Africa - A general description of the caves of South Africa is given. This includes a brief account of caving techniques and aspects of research on the geology, hydrology, morphology and mineralogy of the caves. Although caves systems are well developed in the country, a surface karst morphology is often non existent. Throughout emphasis is placed on the variable nature of the caves resulting from differences in lithology, e.g. complex hyperphreatic mazes in Proterozoic dolomite, shallow phreatic tubes in late Precambrian limestone, phreatic caves in soft Miocene lime-stone, and unusual vadose caves in quartzite and diabase.

Les karsts des Pyrnes-Orientales, 1989, Salvayre, H.
The karsts of Eastern Pyrenees (France) - Karsts in the Eastern Pyrenees occur in Palaeozoic limestones (syncline of Villefranche-de-Conflent) or in Mesozoic limestones. Horizontal caves of several kilometres (En Gorner, Fuilla, Les Ambullas) are found in the Palaeozoic; but the numerous shafts are in the Mesozoic limestones. The subterranean waters circulate freely in the upper parts of the massif (Fontrabiouse), while there are many saturated karst in coastal areas (Font-Estramar). Classical types of surface karst features develop in the Corbires massif; elsewhere, in the Palaeozoic limestones, this karst morphology does not exist or is hidden under covers.

General characteristics of the landforms in the Alps and Julian Prealps and in Trieste Karst., 1989, Vaia Franco
The morphology of the Julian Alps and Prealps and of the Triestian Karst are here shortly described; the structures, which defined its origin and development, are also considered. We can notice some cliffs which follow one another from the State boundary to the Adriatic sea; they are made up by lithologic successions, which repeat themselves according to the latitude. Anyway we recognize a general outcropping of rock masses which are decreasing little by little southward as regards the altitude, the age and than the erodibility. There are some differences between the western (Carnian) and the eastern (Julian) bend of the regional mounts according not only to the latitude but to the longitude, because of the lithology. In fact, the Julian mountains often look like the Dolomities in the northern zone. The southern ones, particularly near the high alluvial plain, are rounded and gently dipping. The drainage networks are quite different too. In the upper zone it is a trellis net, in the lower one is locally a trellis net and than it becomes a dendritic system. The glacial erosion follows the same principle too, coming southward along the main and the subordined valley cuts. At last, the Karst morphology shows itself strongly conditioned by the structural scheme as well as by the lateral lithologic changes. It comes out an anisotropic whole of surface forms and of subsurface ones, clearly referred to those reasons. The whole area here described shows moreover a high evolutive dynamics, connected with the recent tectonic phases.

Observations morphologiques sur le gosystme karstique du Rupt du Puits (Meuse, Lorraine), 1995, Jaillet S. , Gamez P.
The karst system of Rupt-du-Puits is situated east of the Paris basin (Barrois and Perthois), in the Portlandian limestones covered by sands and clays of Lower Cretaceous. It presents 21 km of surveyed passages in several networks (catchment = 13 km2). In this typical covered karst (cryptokarst), we observe two kinds of alimentation: rapid (swallow holes) and slow (wet soils). On the exokarst, the valleys move by retreat of swallow holes and karst stepping. In the endokarst, the variations of the base level determine several stages of stream piracy (elbows of capture). The karst morphology depends on climatic changes and the evolution of the drainage pattern during the Upper Pleistocene.

Limestone karst morphology in the Himalayas of Nepal and Tibet, 1996, Waltham A. C. ,
Karst and caves are minor parts of the Himalayan landscapes of Nepal and Tibet. Solution decreases at high altitude on the Nilgiri Limestone of the high Himalaya, and karst features are immature. Limestone outcrops north of the Himalaya, in the rain shadow are characterised by microkarren, indicating minimal solution rates. Most caves in Tibet are modified by frost shattering. Across the region, karst is restricted by both climatic factors and the extreme youthfulness of the landscapes. There is no positive evidence for the survival from the Tertiary of fossil karst features in Tibet. The large cave and the associated collapse gorge at Pokhara, Nepal, are essentially piping failures in limestones only about 500 years old

The role of high-energy events (hurricanes and/or tsunamis) in the sedimentation, diagenesis and karst initiation of tropical shallow water carbonate platforms and atolls, 1998, Jan F. G. B. L. ,
Karst morphology appears early, even during carbonate sediment deposition. Examples from modern to 125-ka-old sub-, inter- and supratidal sediments are given from the Bahamas (Atlantic Ocean) and from Tuamotuan atolls (southeastern Pacific Ocean), with mineralogical and hydrological analyses. Karstification is favoured by the aragonitic composition of bioclasts coming from the shallow marine bio-factory. Lithification by aragonite cements appears as a rim around carbonate deposits and dissolution and non-cementation start at the same time on modern supratidal deposits (Andros micrite or atoll coral rudite) and provoke the formation of a central depression on small or large carbonate platforms. In fact, this early solution of the centre of platforms is closely related to the location of each of the studied examples on hurricane tracks. High-energy events, such as hurricanes and tsunamis, affect sediment transport but hurricanes also affect diagenesis as a result of the enormous volume of freshwater carried and discharged along their paths. This couple, lithification- solution, is localised at sea level and accompanies sea-level fluctuations along the eustatic curve. Because of the precise location of hurricane action all around the Earth, early karstification by aragonite solution, cementation and supratidal carbonate sediment accumulations thigh-energy trails) act together on all the platforms and atolls located inside the Tropics (23 degrees 27') between roughly 5 degrees-10 degrees and 25 degrees on both hemispheres. However, early karstification acts alone on shallow carbonate platforms including atolls along the equatorial belt between 5 degrees-10 degrees N and 5 degrees-10 degrees S. These early steps of karstification are linked to the ocean-atmosphere interface due to the bathymetrical position of shallow carbonate platforms, including atolls. They lead to complex karstified emerged platforms, called high carbonate islands, where carbonate diagenesis, together with the development of bauxite- and/or a phosphate-rich cover and phreatic lens, will occur.

Karst morphology across a steep climatic gradient, southern Mount Hermon, Israel, 1998, Frumkin, A. , Shimron, A. E. And Miron, Y.

The southern slopes of Mount Hermon display a multiphase karst system developed over a climatic and topographic gradient. The important factors are certain geologic features, altitude defining the climatic belts, the local slope gradient and the paleohydrological evolutionary history of the mountain. Doline density and cave depth tend to increase with altitude. Active vadose caves draining dolines are more common at the upper, alpine zone, while ancient phreatic caves appear in the lower altitude slopes. Intense fissuring of the authigenic karst surface favors diffuse seepage over concentrated flow, restricting conduit size.

Denuded caves - an inherited element in the karst morphology, the case from Kras , 1998, Mihevc Andrej, Slabe Tadej, Š, Ebela Stanka

Relief features due to denudation lowering of the surface or due to changes of karst caves in the epikarstic zone are described. Three genetical types of superficial relief features controlled by denudation of rocks above the caves are treated. These are roofless caves, a series of dolines above larger cave passages and individual dolines due to denudation of vadose and phreatic shafts. These features must be genetically distinguished from features due to collapse processes above caves.
