Abstract

One hundred and seventy rock glaciers have been identified by use of aerial photographs in the southern Central Pyrenees. Through the use of statistical techniques (quadrat analysis, Poisson distribution analysis and variance‐mean ratio test), differences in lithology and fracturing density are shown to be important controls over their distribution. Cent septante glaciers rocheux ont été identifiés sur des photos aériennes des Pyrénées Centrales Méridionales. Par l'emploi de techniques statistiques, il est démontré que les facteurs principaux qui contrǒlent leur répartition sont les différences lithologigues et les variations dans la densité de fracturation de la roche.
