Abstract

DESCRIPTION OF SOME DEPRESSIONS SITUATED IN KARSTIC MOUNTAINS OF HIGH-ALPINE TYPE. THE DIFFERENT SHAPES OF THIS DEPRESSIONS ARE CONDITIONED BY THE STRUCTURE. THEIR ORIGIN DEPENDS UPON SEVERAL PROCESS: A) OVERDEEPENING TYPICAL OF GLACIERS| B) DEEPENING OF THE BASIS AT THE TIME OF GLACIER MELTING (RESIDUAL GLACIER STAGE)| C) PRESENT DAY DEEPENING DUE TO THE CO RICH WATERS OF SNOW MELTING AND THE IMPORTANCE OF CRYOCLASTIC PROCESSES. IN EVERY CASE THE STRUCTURAL CONDITIONS AND THE ROCK FRACTURE PLAY A DETERMINING ROLE. FINALLY, THE SEQUENCE OF PROCESSES LEADS TO AN AUTO-CATALISIS PHENOMENON FOR THE LARGEST AND OLDEST BASINS.
