Abstract :
[en] From some measurements of pH and hardness in melt-waters of the Marmolada Glacier (Dolomites), it appears that these waters are - or at least were in September 1965 - strongly alkaline and not very aggressive towards their limestone bedrock; pH on the glacier and just nearby are between 8.8 and 7.8. Calculated CO2 pressure is lower in the glacier (3.6 10 -4 atm) than in anyone of four other samples analysed in the region. [fr] Quelques mesures de pH et de dureté montrent que les eaux de fonte du glacier de la Marmolada sont nettement basiques (pH entre 8,8 et7,8) et peu agressives vis à vis du calcaire sur lequel elles coulent.
