The living environment of Stenasellus virei Dollfus, 1897 (Asellote troglobe Crustacean): preliminary results., 1971, Magniez Guy
Stenasellus virei is now known from 77 localities (caves, phreatic waters and underflow of some rivers) of the eastern Aquitanian basin, central and eastern Pyrenees, and of Spain. A classification of the different biotopes of the species is attempted herein, and some of their characteristics are summarily described. This cavernicolous species can now be viewed in a new light, as much ecological as systematic or biogeographic.

Prsentation splologique du massif des Fanges-Roc-Paradet (Aude/Pyrnes orientales), 1987, Ournie, B.
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.

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.

Anomalies des teneurs en oxygne atmosphrique mesures dans le rseau Fanges-Paradet (Aude / Pyrnes-Orientales), 2002, Ourni Bernard, Ostermann Jeanmichel
Measures of atmospheric O2 and CO2 in the cave system of Fanges-Paradet (French Eastern Pyrnes) - In the cave system of Fanges-Paradet and in several caves of Region Languedoc-Roussillon (in Corbires mountains, High Aude Valley and Larzac Causse), successive measuring of atmospheric O2 and CO2 contents have been taken in 1997, 1998 and 2001. The aim of the paper consists in getting more accurate composition of endokarstic atmosphere. Abnormally low contents in O2 appear, especially in the deep parts of puits de lOurs, grotte de la Coume dels Adoutx and grotte TM 71. Several explanations may justify these anomalies.

Reactive transport modeling and hydrothermal karst genesis: The example of the Rocabruna barite deposit (Eastern Pyrenees), 2006, Corbella M, Ayora C, Cardellach E, Soler A,
In western Europe and North Africa, many sulfide and barite deposits appear to be related to the pre-Triassic paleosurface. Some of these mineralizations have traditionally been interpreted as the result of mineral fillings of previously formed karstic cavities. However, reactive transport modeling suggests that those minerals may have originated at depth and simultaneous with the cavity in the carbonate rocks. Numerical simulations using the Rocabruna deposit as an example recreate the genesis of such cavities and their filling by new minerals in a hydrothermal environment. Two warm (T = 150 [deg]C) fluids with different compositions but both saturated with dolomite were allowed to mix at a fracture intersection; the resulting solution strongly corroded the dolomite host rock and was able to create large voids in a hundred thousand year time scale. Our results show that equidimensional cavities originate from mixtures with equal fluxes of the contributing fluids, but elongated dissolution zones appear when the flux ratios were different from unity and the slowest flow direction coincided with the longest dimension of the void. Moreover, when the fluid mixture was dominated by a diluted and slightly alkaline groundwater instead of a 50-50 mixture with an acidic brine, dolomite dissolution or corrosion was more effective. Sulfide minerals precipitate around cavity walls replacing the host dolostone as the dolomite dissolution reaction couples with that of sulfide precipitation. This coupling produces some porosity, which is negligible compared to that caused by the mixing itself. Barite may also precipitate inside the forming cavity, but as the sulfate mineral precipitation reaction is not coupled with that of dolomite dissolution, barite grows in open space
