SPELEOLOGY OF THE FANGES-ROC PARADET MOUNTAIN KARST (AUDE /EASTERN PYRENEES, FRANCE) - The Fanges-Roc Paradet Mountain karst (S = 40 km2) contains a large underground cave, the " Cthulhu Dmoniaque-Puits de lEngoulevent " system (L = 13km, D = -302m). This region of Fenouilldes is characterized by a mediterranean climate and presents different surface karst features (pavements, depressions, dry valleys). Synthesis data are given in hydrogeology and speleology. The complexity of subterranean drainage and caves can be explained by an old karstification begun during the mio-pliocene uplift, from an eogene peneplain. The association Arkham co-ordinates the researches and prepares some publications.

Paleoenvironment and speciation in the cave beetle complex Speonomus delarouzeei (Coleoptera, Bathysciinae), 1988,
Deprecated: Function get_magic_quotes_gpc() is deprecated in /home/isthin5/public_html/addon-domains/ on line 943
Juberthie Christian
In the eastern part of the Pyrenees (France) the author describes a scenario of speciation in the cave species complex Speonomus delarouzeei (Coleoptera Bathysciinae); the speciation processes have been initiated by a breakdown of the ecological equilibrium induced during three glacial-interglacial episodes. The scenario is the following: during the first glaciation (2.3-2.1 MY), psychrophilic populations ancestral to S. brucki were selected over the highest elevation of the range, by means of cold effect which produced an adaptive demographic advantage; adaptive characters of troglobitic species (K strategy) take place presumably in relation to colonization of caves and M.S.S.; during the second glaciation (1.7-1.3 MY) and a more recent, S. charlottae, latter S. emiliae, diverged from troglobite ancestors of S. brucki without further adaptive characters, as result from stochastic and historical events. M.S.S. generated during erosional period of glacial event provided ways for migration and new niches for colonization. Bottleneck effect in size population of ancestors, founder effect, and colonization by local population which present genetic and behavioural geographical polymorphism, argue for a rapid speciation, presumably 100,000 years long and 50,000 generations in the case of S. emiliae.

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.

Brouwir Christine, Tercafs Raymond
The population size of three troglobitic species of Speonomus (Coleoptera Bathysciinae) from the Pyrenees, intentionally introduced in 1969-1970 into the "Grotte de Ramioul" cave (Province of Lige, Belgium) has been studied using the mark-recapture technique. It has been shown that the three cave levels possess large Speonomus populations (upper network: 12,718; middle network: 13,902; lower network: 18,249 individuals) and that the superficial underground environment is also colonized, including the schist area. The most abundant species is Speonomus longicornis (relative frequency between 0.73 to 0.89). The two other species are present in the relative frequency between 0.04 and 0.23 for S. diecki, and between 0.03 and 0.11 for S. stygius. The overall Speonomus population size in the cave is estimated at 44,000 individuals.

Pertes du Gave d'Ossau et naissance du Neez (Pyr.-Atl., Fr.), 1992,

SINKS OF THE OSSAU GAVE AND SOURCE OF THE NEEZ RIVER (PYRENEES) - A Gave is a mountain torrent in the Pyrenees. The water supply of the city of Pau is depending almost entirely on a karstic spring called Oeil du Neez (the Neez Eye, which means spring of the Neez). LOeil du Neez is the main resurgence - among several others - of water sinks in the Gave bed across the urgonian limestone ridge of Arudy. Development of this karstic system through the complex structural setting of a frontal thrust has been favoured by the geomorphic evolution of the Arudy basin, dammed to the north by a morainic loop, but also by the presence of highly suitable hydrodynamic and tectonic conditions (water head and fractures network). Water quality of the Oeil du Neez is closely depending on Gave water quality. However, the catchment area proper, of this resurgence, exerts its own chemical influence.

The karst aquifer of the well-known Fontaine de Vaucluse has been recently studied, results have been got about delimitation of the system and its working. Geological data (lithology and structure) have allowed to delimit an 1115 Km2 intake area including Ventoux-Lure north facing range (1,909-1,826 m) and the Plateau which is prolonging it southwards (Fig. 1 and 2). The average altitude of the whole area, obtained by balancing elevation belt surfaces, is about 870 m. This elevation squares with results of tracing tests (Fig. 3), environmental physical, chemical and isotopic tracings, that allow to value a 850 m average altitude for the intake area (Fig. 4). The moisture balance has been computed from an altitude belts climatic model, using local rain an temperature gradients (Fig. 5 and Table II), because the weather network is not representative. So, rainfalls rise of about 55 mm per 100 m elevation and temperature decreases of about 0.5-degrees-C per 100 m. The consequence of these two antagonist phenomena is the quasi constant value of actual evapotranspiration on each altitude belt. With the Fig. 7 organigram, curves of effective rainfalls and infiltration coefficient versus elevation can be plotted (Fig. 6). This computation shows that 3/4 of the total and the whole of dry season effective rainfalls are provided by the part of the intake area situated above the average altitude: on the lowest belt, effective rainfalls are only 120 mm per year and increase to 1380 mm on the upper section (Fig. 8 and Table 1). The weighted effective rainfalls are about 570 mm per year for the whole intake area. Hydrodynamical and physico-chemical studies show, despite its large size, the weak inertia of the system, so proves its good karstification, that confirms for the whole system the pin-point speleological observations. The discharge of the spring, which average value is 21 m3.s-1 (only 18 for the last ten years), can exceed 100 m3.s-1 and the minimum has never been lower than 3.7 m3.s-1 (Fig. 9). When it rains on the intake area, the increase of the discharge is very sudden in a rainy period : one to four days. This short delay is due to seepage through epikarst and unsaturated zone. During dry periods, the spring reaction is deadened, due to storage in the unsaturated zone. The silica content distribution was plotted during several hydrokinematical phases (Fig. 10). It shows: an almost unimodal distribution for the 8 km2 fissured limestone aquifer of Groseau; a multimodal one for the 1115 km2 karst aquifer of Fontaine de Vaucluse. This proves that karstification is more important than size in the response of the system. Weak summer rainfalls do not influence the discharge, nevertheless they influence chemistry of the spring water, and so interrupts the water depletion phasis. Then, the decrease of discharge can continue after the end of the chemical depletion phasis, water which is overflowing after summer rainfalls (in a dry period) is influenced hy the chemistry of seepage water : on the graph of a principal components analysis, done on chemical variables. an hysteresis phenomenon can be seen (Fig. 11). A discriminant analysis (Fig. 12) confirms that these autumn waters, with high ratio seepage tracers, are not reserve waters from the saturated zone. The ratio of reserve water in the total discharge, is preponderant: 3/4 and 2/3 respectively of the yearly runoff volumes for 1981 and 1982 (Fig. 13), but an important part of these reserves can be stored in the unsaturated zone. This storage capacity can be valued by different means: transposing to Vaucluse (1115 km2) the volume measured on another karst system in the Pyrenees (13 km2); it gives about 100 million m2; using setting parameters of Bezes model (1976) on the same aquifer: it gives 113 million m3; using depletion curves, that show, for instance during the 1989 summer and autumn dry period, a 80 million m3 volume. In all cases, we get a value of about one hundred million m3 for the storage capacity of the unsaturated zone. With a 20 m range of fluctuation for the water table and with a 10(-2) specific yield, on a 500 to 1,000 km2 saturated zone, the zone of fluctuation can release about 10 to 20 million m3. Then, the volume of water stored in the whole saturated zone, with a 300 m minimum thickness (depth of the waterlogged pit of the Fontaine), a 500 km2 minimum surface and a 10(-3) specific yield, is about 150 million m3, including 27 million m3 stored in the channels. So, the unsaturated zone represents a significant part of the whole storage capacity and most of the yearly renewable reserves. Paradoxically, the biggest french spring is not tapped at all; as its intake area is neither a regional nor a national park, no general protection covers it : because of its good karstification, the vulnerability of the system is important. Good quality of water is attributable to the low population and human activities density on the intake area (4 A great part of the intake area is uncultivated (large forest and ''garrigues'' areas). Due to the lack of surface water and scantness of soils, agriculture is not intensive (lavender, thyme, sage and bulk wheat fields. meadowlands). On the mountainous zone, roads are salted in winter and snowmelt water can reach a significantly high chloride ratio than in a natural climatic functioning (for instance 25 mg.l-1 in Font d'Angiou where the ratio would have been 3 mg.l-1). As tourism is developing both on the mountain and on the plateau, the management of the highest intake area must be carefully held: its part is preponderant in the feeding of the system

In 1982 and 1992 cavers observed the contamination of the B3 and Couey-Lotge underground rivers emerging at the Issaux springs This contamination was thought to be caused by the PSM water purificatlon station which discharges effluents into a fracture. The ARSIP and the LGPA laboratories were asked by the DDA (Pyrenees-Atlantiques administration) to carry out an hydrogeological study to prove the origin of this contamination and determine the limit of the Issaux catchment in the Guillers area in order to find a new site for a modern water purification station. Three uranine tracings were made (Water purification station - B3 underground river - BG. 106 shaft). The first two tracings emerged at the Issaux springs and the third tracing came out at the Bentia spring (Sainte-Engrace). These tracings confirm the hypothesis on the surficial basin limits between Issaux and Saint Vincent.

Isolated carbonate platform of Caniego, Spain: A test of the latest Albian worldwide sea-level changes, 1997,

Fernandezmendiola Pa, Garciamondejar J,
The upper Albian Caniego carbonate platform consists of a 20-m-thick unit of rudist- and coral-bearing limestones that crops out at the northern margin of the Mena diapir in northern Spain, The limestones were deposited on top of a slowly subsiding area, the Mena paleohigh, a diapiric-induced horst bounded by synsedimentary faults, The Caniego limestones originated in shallow warm tropical waters following a widespread marine transgression at the base of the foraminifera Rotalipora appenninica zone (ammonite Stoliczkaia dispar zone), Around the middle part of the appenninica zone the Caniego limestones underwent subaerial exposure and karst development, Fibrous calcite cements filled the bulk of the fissure-dike and dissolution cavities, Field, petrological, and geochemical data indicate that the fibrous calcites are meteoric flowstones, delta(18)O values in these cements range from -3 parts per thousand to -4.5 parts per thousand and delta(13)C values range from -7 parts per thousand to -14 parts per thousand (relative to the Peedee belemnite [PDB] standard), Thick wedges of nearshore shallow-marine siliciclastic sediments were deposited in paleotrough areas surrounding the Caniego paleohigh while the platform was subaerially exposed, The carbonate platform was drowned in early Cenomanian time and hardground-condensed facies developed during this period (Rotalipora brotzeni zone), Deeper water noncondensed marry sedimentation was reestablished in the mid-Cenomanian (Rotalipora reicheli zone), Comparison of the Iberian Caniego limestones with worldwide successions suggests a coincidence in the timing of platform formation emergence and drowning in several basins of different lithospheric plates, Nevertheless, an overall lack of coordination of sea-level histories from different basins may be related to tectonic movements of the lithospheric plates, Plate rearrangement is invoked as the primary control on relative sea-level changes and sequence development

Painted caves are karstic cavities here considered as stable physical systems in a state of dynamic equilibrium. From the example of the Gargas cave, we show that introduction of excess energy (visitors, lighting) causes a loss of stability and introduces a risk of degradation in the cavity. From different approaches, we identify the periods and the causes of instability and we determine the maximum level of introduced energy which would preserve the conservative properties of the cavity. These results allow cave equipment and visitor capacity compatible with satisfactory conservation conditions to be defined.ResumeLes grottes ornees sont des cavites karstiques considerees comme des systemes physiques stables en etat d'equilibre dynamique. Nous montrons, a partir de l'exemple de la grotte de Gargas, que l'introduction d'une energie excedentaire (visiteurs, eclairage) destabilise le systeme naturel, determinant ainsi un risque de degradation dans la cavite. Differentes approches permettent d'identifier les periodes et les causes de la destabilisation et de determiner le niveau maximum d'energie introduite permettant le maintien du pouvoir conservatoire de la cavite. Ces resultats permettent de definir des amenagements et un niveau de frequentation compatible avec des conditions de conservation satisfaisantes

A succession of Miocene rodent assemblages from fissure fillings in southern France: palaeoenvironmental interpretation and comparison with Spain, 1999,
Deprecated: Function get_magic_quotes_gpc() is deprecated in /home/isthin5/public_html/addon-domains/ on line 943
Aguilar Jp, Escarguel G, Michaux J,
An Early to Late Miocene sequence of rodent assemblages from southern France has been quantitatively studied. The resulting pattern seems very similar to a contemporary sequence from central Spain (Calatayud-Teruel Basin). The fossil mammal-bearing localities are of different types: mainly karst infills in France and localities situated in sedimentary basins in Spain. In order to interpret the fossil record, a comparison has been made between southern France faunas of similar age but collected in karst infills and in basin deposits. There seems to be no difference between the two kinds of faunas and thus there is no indication that karst infills systematically give a picture of drier and more open environments. Both types of localities may give a similar relative abundance of taxa and when differences exist they can be attributed to local conditions. The comparison between southern France and the Calatayud-Teruel Basin (central Spain) shows that: (1) similar trends occurred in the two areas; (2) differences between spectra were more important during the late Early Miocene than during the Middle Miocene; (3) the shift between the late Early Miocene and the Middle Miocene environments in southern France does not seem to be correlated with. a general drop in temperatures as inferred from the analysis of central Spain faunas.
