RECENT INVESTIGATIONS ABOUT THE NIAUx-LOMBRiVE-SABART KARST (Arige, France) - Several recent investigations concerne this important system (14km). The P. Sorriaux sedimentologi-cal thesis (1982) establishes that the ancient troughflows have inverted their direction during an evolution of at least 400,000 years (isotopic dating from calcite) under glacial conditions. The C. Andrieux, J. Brunet and Ph. Renault speleometeorological studies (1974-1983) concerning the thermic equilibrium pattern and the carbon dioxide distribution suggest an atmospheric model. The closing or opening of some the locks (sumps, doors) induces the changing of a barometric causality into a thermic one with the production of a general air flow.

Smart, Charles Christopher

Alpine karst throughout the world has been affected by past glaciation, and yet little is known of the interactions between glacier ice and karst. This dissertation attempts to gain some understanding of the problem through the study of the Castleguard Area, Alberta, where a karst aquifer is presently overlain by temperate glacier ice.
Quantitative fluorometric tracing and hydrometric measurements generated a broad data base on aquifer behaviour. Tracer breakthrough curves were interpreted using a new systematic approach which considers an explicit set of processes likely to affect the particular tracer under the given experimental conditions. Non-linearity in aquifer behaviour and rapid groundwater velocities demonstrated the aquifer to be an extreme conduit type Conduit springs are elements in a vertical hierarchy in which the topmost springs are "overflows" and exhibit greater flow variability than their associated "underflows". A numerical model was developed to simulate a conduit aquifer. It demonstrated that pulse train and recession analysis widely accepted methods of karst aquifer investigation, could be rather misleading when applied to conduit aquifers.
Interactions between ice and groundwater were observed at two scales: regulation water appeared to feed a diffuse percolation system and supraglacial melt passed into subglacial conduits which entered open vadose shafts. Karst is unlikely to be entirely subglacial in origin because of the limited aggressiveness of subglacial waters.
The Castlegaurd karst appeared to have originated preglacially in response to the breaching of impermeable caprock. Glaciation re-ordered the landscape and produced abundant clastic debris which subsequently blocked or obstructed karst conduits. Much of the resulting karst is paragenetic and comparatively immature due to glacial disruption and slow growth rates. Geomorphic and hydrologic interactions between ice and karst depend intimately upon the relationship between the geographic zones of the glacier and the aquifer.

THE PART OF THE QUATERNARY INHERITED FEATURES IN THE ALPINE KARSTS: THE EXAMPLE OF THE NORTHERN ALPS - In the western part of the Alps, limestone mountains have been built mainly during Miocene and Pliocene. The relicts of pre-quaternary alterations or karstifications are scarce and difficult to identify. The most part of the morphological features can be related to the quaternary glacial stages. The main landforms of the high and low alpine mountains are described. The glaciers and their melting waters have excavated deep gorges-valley and caves.

THE UNDERGROUND SYSTEM OF DENT DE CROLLES (ISERE, FRANCE) - The Dent de Crolles plateau (highest point: 2062m asl.) is the southermost part of the great syncline of the eastern Chartreuse. This syncline stretches from Grenoble to Mont Granier, above Chambery. The karst of Dent de Crolles develops in urgonian limestone, and in spite of little surface (2km2), it contains the most important underground system of the French Alps (about 52km). In spite of important oceanic rainfall, underground flows only drain some small galleries. Karst genesis is related to the glaciers.

PALEOZOIC KARST IN ANTARCTICA - Karst features in Antarctica have been rarely observed. In their study on the geology of the Beardmore Glacier area in the Transantarctic Mountains (south of Ross Ice Shelf), BARRET and al. (1968) describe a pre-glacial karst topography (Mt. Counts) and especially a former cave (diameter 10 m) 10 m below the erosion surface and filled with coarse green sandstone. Shaped in the "Shackleton limestone" (Low to Middle Cambrian) probably during the Permo-Carboniferous (hercynian cycle), this karst is fossilised by the Pagoda formation, a permian tillite of the Beacon sequence (Devonian-Permian- Triassic).

CAVES OF CENTRUM LAKE AREA (NE GREELAND) - In 1983, M.Chiron, G.Favre, J-F. Loubire and J-P. Ttard identified a network of caves located in the extreme nord-east of Greenland. A cambro-silurian limestone zone stretches out to the south-west of Kronprins Christians land, the northern extremity of the great range of folded mountains of eastern Greenland. During an era characterised by the absence of permafrost and by a warmer climate favouring underground water circulation, these limestone formations were hollowed out by karstic river system. Such climatic conditions have long ceased to exist. During the major glaciations of the Quaternary period, the cavities were greatly modified. Glacier movements, cutting into the plateau, broke up the networks. The original underground deposits were then altered by allochtonous material of aeolian and morainic composition. Severe and ongoing frost shattering has added to this destructive process. It is hoped that this article will help to draw attention to these caves and to the more general subject of paleo-climates, especially their effects in the polar region during the Plio-Pleistocene transition (Electron Spin Resonance method on stalagmite and discovery of a mycelian hypha into calcite structure).

Karsts of the alpine foreland north to the French Western Alps: glacial origin of the underground systems - Karstic mountains are described between Rhne valley and the border of Northern Alps. The influence of quaternary glaciers is evident for surface landforms and the existence of inactive canyons can be explained only by glacial outflows. Large underground caves and systems such as La Balme, Les Echelles, contain numerous blocks and pebbles of alpine rocks. Except in some places of the alpine mountains, the pre-quaternary karstic evolution cannot be investigated. Now the rate of karstic corrosion is too low and waters are unable to produce large caves. Only the mechanical action of whirling glacial flows in some pre-determinated places can explain the presence of large caves in these low karstic mountains. The formation of these kind of caves can be correlated with the existence of the actual canyons and defils along this part of the Rhne river.

Drainage Evolution in a Tasmanian Glaciokarst, 1989,
Deprecated: Function get_magic_quotes_gpc() is deprecated in /home/isthin5/public_html/addon-domains/ on line 943
Kiernan, Kevin

The intensively glaciated mountains of the Picton Range - Mt. Bobs area in southwestern Tasmania contain prominent karst features that have been developed in carbonate formations of Devonian, Ordovician and possibly Precambrian age. This paper reviews the extent of the karst and glacial features and records the tracing of the underground drainage from the alpine Lake Sydney. Glacial erosion has exposed areas of limestone to karstification and glacial diversion of drainage has played a critical role in the evolution of the present underground drainage patterns. Prior to the late Last Glacial Stage the deflection of marginal meltwaters from the former Farmhouse Creek Glacier against the Burgess - Bobs Saddle led to the development of an underground breach of a major surface drainage divide. Subglacial or submarginal meltwaters associated with a much smaller glacier that developed in the same valley during the late Last Glacial Stage probably played a significant role in the breaching of a minor divide within the Farmhouse Creek catchment. This led to the development of an underground anabranch of Farmhouse Creek that by-passes the glacial Pine Lake. However, it is possible that the latter diversion is entirely Holocene in age and is related to postglacial dilation of the limestone rather than meltwater flows.

Le karst du massif Moucherotte / Pic Saint-Michel (Isre, Vercors), 1991,

The karst of Moucherotte/Pic Saint-Michel (Vercors, Isre, France) - The massif of Moucherotte-Pic Saint Michel is located in the northeastern corner of the Vercors, in the area of Lans-en-Vercors and Saint-Nizier-du-Moucherotte. As anywhere in Vercors, this area is strongly marked by a dense karst relief. It harbours underground systems. Recent dye tracings (respectively from Sierre shaft, Choucas shaft, and Ira's Hole) allowed to determinate precisely the boundary of the catchment of the source called Bruyant. This basin spreads out from the Moucherotte to the Pic Saint-Michel, thus including a surface of 12km2. This is confirmed through the water balance. Of the 1600mm of yearly rainfall, 70% is infiltrated toward the source of the Bruyant. The water is conveyed through a main drain, probably mostly vadose, at the base of the recumbent fold. The landscape is due to the Quaternary processes. The two great landslides of "col de l'Arc" and of "Peuil" date back to this time. The glaciers have sculptured huge "combes" where many caves open, ancient places where sub-glacial waters were swallowing. These sub-vertical caves (which can measure up to 300m deep) with shafts and meanders, flow through large horizontal galleries older than the Quaternary (Combe Oursire shaft, Vallier cave). These galleries, hidden away in this huge limestone mass, are the witnesses of an earlier and very elaborate subterranean drainage. This system is entirely different from our present drainage system.

THE ALPINE KARST 0F RETEZAT M0UNTAINS (ROMANIA) - The limestone area of the Retezat Mountains (2079 m), in the Carpathian range (Transylvania), is the principal alpine karst of Romania. It is formed by a syncline structure of jurassic limestone covering a crystalline precambrian basement. The mountain climate is wet (1400 mm/year) and continental. The glacio-karstic morphology (glacial cirque, dry valleys) is developed on a tertiary polygenic surface folded and uplifted since the Oligocene and Neogene. The catchment basin (85 km2) feeds the Izvorul Cernei karst spring (0,5-10 m3/s), the most important of Romania. Water tracings (s = 55 m/h) and statistical studies on caves suggest the development of a complex karst system. 50% of underground waters come from the running off on the precambrian basement and explain the rate of sodium. The majority of the potholes and glacires are situated above 1700m; the deepest is Stna Tomii cave (-136m) with a 115m direct pit.

Bienfait, P.
KARSTIFICATION AND PALEOGEOGRAPHICAL EVOLUTION OF THE JURA (Fr.) - The karstification started at the beginning of the Tertiary, and the process is still going on today. During the Eocene, modifications brought about under the tropical climate resulted in siderolithic deposits (siliceous sands, ferruginous soils), which can be found in some fossil karsts. In the Oligocene, active tectonics modified the Eocene surface. Erosion during the Miocene levelled the Jura Mountains into a peneplain even though the climate remained tropical. Toward the end of the Miocene, present-day structure and landforms were produced when the main folding, subjected at the same time to powerful erosion, occurred. During the Upper Pleistocene the climate became cooler and wetter. At least two glacial periods have been recognised in the Pleistocene. Present-day karst landforms and most of the caves can be considered as being shaped during the Plio-Quaternary. The karst fillings of the Quaternary provide evidence of the extension of the Wrm and Riss glaciers.

GYPSUM KARSTIC LANDFORMS IN VANOISE: the alpine and glacial valley of Vallon du Fruit-Gbroulaz (Alps, France) - In the inner part of the northern french Alps, the higher regions of the Vanoise offer outcrops of Triassic gypsum of which the surface and thickness vary. In the vallon du Fruit, the Gbroulaz glacier partially covers a long strip of gypsum, which reaches its highest point at the Roc de la Soufrire (2940 m). Rivers and springs in the vallon du Fruit are fed both by sub-aerial glacial outflows and by karstic underground flows, which are pro-glacial and sub-glacial. A very low chemical dissolution exists under the glacier and along the fast pro-glacial underground and sub-aerial flows, whereas the rate of karstic denudation is high in the margin of the glacier where it reaches 1500 mm/ky at around 2500m (1 ky = 1000 years). The formation and evolution of the dolines is rapid and occurs through underground sucking and dissolution once the area is deglaciated, thanks to underground active flows fed by the glacier and snow melting. Gypsum domes are uplifted under the effects of neotectonic movements and postglacial decompression brings about considerable superficial fissuring because of the elasticity of the rock. Over 10,000 years, the morphogenesis of these domes in the humid and cold climatic conditions of these high alpine mountains has transformed them into perforated ladle and domes. Small outcrops are changed into monoliths or gypsum inselberg. A model of the geomorphologic post-glacial evolution of these domes, over some 20,000 years, is proposed.

TRADITIONAL EXPLOITATION 0F CAVES IN SOUTH-EASTERN France - In south-eastern France (Jura, Prealps and Provence), the karstic caves have long been used as dwellings and exploited for ice or as mines. The ice caves (or glacires) of the Jura and Prealps (Bauges, Chartreuse and Vercors) were used by local inhabitants from the Middle Ages onwards even though the actual trade of ice towards the big cities (Grenoble, Lyon and Paris) was only to begin in the 19 century. Phosphate deposits are used as fertilizer in local farming. Since the 17th century speleothems have been extracted for use as ornaments and some caves, of which the Aven du Plan, Alpes-Maritimes, is a typical example, have become stalactite mines. The Gouffre Maule in the Chartreuse area is a noteworthy example of a mining cave in which the exploitation of iron was begun before the 12 century by local monks. The complex tasks carried out in these caves (such as the setting up of scaffolding and the digging of galleries) provide clear evidence of the importance once given to local resources before the industrial age.
