The cavernicolous and endogeous Coleoptera Carabidae, actually (1972) known from the Anatolian peninsula (here considered together with Armenia, the Caucasus and the mountains of Lebanon), are examined and discussed. They belong to the tribes of Anillini, Trechini (Neotrechus, Aphaenops and Duvalius lines), Pterostichini, Molopini, Sphodrini. The cavernicolous and endogeous Anillini, Pterostichini and Sphodrini from this region have clear relations with the balkanic groups and may be considered as East-Mediterranean faunistic elements. On the contrary, the Trechini of the Neotrechus line are more related to the Caucasian groups, those of the so-called Aphaenops line are endemic of the Caucasus and of the Crimea, and the Duvalius are partly related to the Caucasian species, partly isolated and with uncertain relationships (perhaps with some Greek species or with the Algerian Trechopsis, and perhaps with some species of the Apennines).

The fracturation of the sub-autochthonous massif of the Azerou el Kebir is not fundamentally different from that of the adjoining allochthonous massif; where the structures are due to an Alpine phase, known as the Atlas phase. As with all fractures, karstification only exploits certain of them, without having any linkage to their statistical importance, caves have developed following fractures which are qualitatively important, but are poorly represented quantitatively. The study of the karstification therefore, confirms his complementary to the structural analysis in order to elucidate the technical problems of fracturation in the region.

In North-Africa, the karst of Djurdjura Mountains is important because it shows high-alpine characters. In others papers, we have studied shallow morphology and speleological explorations. Here, we describe the caves: morphology, qualitative hydrology and fillings. These cavities are replaced in their morpho-structural context. We make distinctions between kinds of cavities. Gulfs and resurgences characterize high-alpine karst which is actual. Other caves that have their opening at the middle of slopes are dry, disconnected of actual morphological context. They belong to past karstification phases. From the synthesis of those elements, we show that it is possible to use karstic data in the reconstruction of morpho-structural evolution of a country.

HYDROTHERMAL SPELEOGENESIS IN THE BIBANS (ATLAS TELLIEN, NORTH ALGERIA) - The Azrous are two small limestone mountains jutting out from wide marl spaces (the Tellian sheets) in the region of the Bibans. Their surface is not really a karst but they contain many caves, which have been caused by thermal waters. The seepage is so weak that these caves have been very well preserved and so we can study old geothermal carbonate aquifers. This study shows the main morphological, structural, sedimentological and mineralogical features of such caves.

DATA FOR AN ENERGIZING APPROACH OF THE KARST. APPLICATIONS TO A FEW EXAMPLES OF KARST AREAS - One considers the karst like an open thermodynamic system where the located dissipation of hydrodynamical, chemical and mechanical energies gives to the karst a structurated heterogeneity. One discusses about the modalities of the energy dissipation into the karst. The study of some real examples of karstic networks allows understanding how these theoretical concepts explain their characteristics. One ends by a prospect of research: to consider the karstic system like a dissipative system in the meaning of Prigogine.

EXPLOITATION OF KARSTIC AQUIFERS IN ALGERIA - Some difficulties are specific of the karstic aquifers (hardness of the rocks, depth of the water table, scattering of the clefts). The new drilling techniques (downhole hammer) solve some of these difficulties and many mediterranean countries prospect now such aquifers. They contain very fresh waters, even in arid areas. The deep tube wells are now cheap and easy to elaborate. Depending of geological structure, the hydrogeological behaviour will be different (with more or less permanent water stocks). Some Algerian examples show how the development plan must be adjusted to this structure.

Spatio-temporal chemical evolution of thermo-mineral springs in Monts of Cheffia (north-east of Algeria) - The Mounts of Cheffia, located at the extreme Algerian north-east, are the seat of thermomineral springs. The most visited by the curists are Hammam Sidi Trad, Zatout and Beni Salah. The others are forsaken for lack of arranged accesses. The preliminary results of the study of water of these griffons are presented in this note. The first analyses, of which we are informed, go up at 1968. The data collected (2001, 2002) allowed the physicochemical characterization of water, illustrated by their projection on the diagram of Piper and by the statistical analysis. We could identify several chemical facies and distinguish two groups of griffons:One characterizes unsalted water or not very mineral-bearing and with odor of hydrogen sulphide represented by Sidi Trad. The other characterizes salted water, rich in bicarbonate and out of dissolved CO2.

STUDY OF KARSTIFICATION FROM BOREHOLE DATA. THE CASE OF THE TLEMCEN MOUNTAINS. The Tlemcen mountains are the second largest carbonate massif in the north-west of Algeria, after the one of the Saida mountains. It is a large horst structure trending NE-SW, composed mainly of Upper Jurassic and Lower Cretaceous formations. The aquifers within it constitute the main water resource of the area. They are tapped by more than 160 boreholes, which constitute a great tool for studying the karst, especially its phreatic part. In the holes made by conventional drills, the total loss of drilling mud indicate karstification. The registration of the altitude of those losses permit to recognize the fissured and karstified levels. Three different aspects of karstifications were observed: an important fracturation, seen by complete loss of drilling mud during the drilling, important caves, observed by the free fall of drilling tools, and caves filled by karstic sediments, found thanks to diagraphies and the study of material brought up by the drilling. A statistical analysis of these data permitted to evidence the following elements: The dolomitic facies is much more dominant than the limestone facies; The frequency of incidences slowly decreases with depth; The fracturation is most important in the first 120 to 130 m below the top of the karstified formations, although it does not disappear at depth. In the breakdown zone of Tlemcen, situated in the northern piedmont part of the Tlemcen mountain, 26 boreholes permitted to draw an isopach map of the thickness of the karstic cover as well as the top of the karstified formation. This one shows two hollow zones below 100 m depth in the SW and NE parts. The top of the jurassic carbonates shows a very irregular surface which might correspond to a karstic paleorelief that was drowned by the Miocene transgression. Finally, the last map shows a karstified surface that can possibly be connected to a pseudo-paleo-piezometric surface.

In the Saida area, Algeria, a regional aquifer has formed in Jurassic carbonate rocks. Recharged by direct infiltration and swallow holes on horsts, it discharges into the Saida graben. Geochemical and isotope contents show deep groundwater flow at temperatures of around 100 °C at depth and CO2 of deep origin, developing a hydrothermal karst interconnected with the shallow, classical karst. This particular type of karst aquifer, mixing hydrothermal karst conduits in the phreatic zone and classical karst features in the infiltration zone occurs preferably in active tectonic regions. Such a situation is favourable to productive well boring, consequently to groundwater withdrawal and deterioration of water quality. Still badly known in general, this type of complex aquifer should be studied in depth for an efficient and proper exploitation and protection of the groundwater resource.
