Acta carsologica, XXII (1993) AN ACCOUNT ON STUDY EXCHANGE WITH FRANCE 1993 Due to the tradition since 1979 this year too the researchers ofthe Karst Research Insti- tute ZRC SAZU have taken part at the scientific technical cooperation with France, more precisely URA 903 CNRS (Aix-en-Provence), Laboratoire souterrain du CNRS (Moulis). The visit lasted from October 11 to 19, 1993 and was realized by two geologists mag. Martin Knez and mag. Stanka Šebela. In the first part we visited, guided by prof. J. Nicod and under the authority ofprof. J.J.Blanc the caves Grottes de Baudinard in the Verdon canyon. In the Baudinard canyon's profile four levels ofthe cave systems may be observed. In these caves J.J.Blanc (1992) studied the speleogenesis in respect to tectonic laws. In one ofthese caves, in the Grotte de l'Eglise namely, the prehistoric symbols in the roof sol uti on cups were discovered presenting the sun, stars respectively. The age of these signs is postglacial. Our voyage continued to Montpellier where we were hosted by the Ambert family. We discussed the possibilities for common french-slovene cooperation in future. Near Montpellier and at St. Guilhem le Desert dr. P. Ambert presented us his studies on travertines which is the study topic of several researchers in France. The second part of study voyage was spent in Pyrenees. In small village named Moulis lies world famous Laboratoire souterrain du CNRS where they breed the famous slovene proteus. Within the area ofkarst hydrogeology and chemistry we got a lot ofnew knowl- edge from dr. A. Mangin and dr. M. Bakalowicz who accepted us kindly and presented us their work. D. d'Hulst presented the computer aided program for big
