Proceedings of the National Academy of Sciences of the United States of America. 115 (26): 6602–6607. doi: 10.1073/pnas.1719681115. PMC 6042145. PMID 29891710. Marmolada: You can leave from Canazei and continue up to Passo Fedaia, where, once you reach the pass (2.057 m a.s.l.), you will see the mountain reflected in the waters of artificial Lake Fedaia. Dolomite is widespread in its occurrences, though not as common as limestone. [20] It is typically found in association with limestone or evaporite beds and is often interbedded with limestone. [21] There is no consistent trend in its abundance with age, but most dolomite appears to have formed at high stands of sea level. Little dolomite is found in Cenozoic beds (beds less than 65 million years old), which has been a time of generally low sea levels. [22] Times of high sea level also tend to be times of a greenhouse Earth, and it is possible that greenhouse conditions are the trigger for dolomite formation. [23] In the Valli Giudicarie (Giudicarie Valleys) the recommended access points are from the Val d’Ambiez, above San Lorenzo in Banale, which takes you to Rifugio Agostini, and from Val d’Algone you can reach Rifugio Dodici Apostoli, one of the most isolated, scenic places in the Brenta Mountain Group, with a spectacular view over the Adamello and Presanella mountain ranges.

Thus dolomitization likely increases porosity and contributes to the sugary texture of dolomite. [16] The dolomite problem and primary dolomite [ edit ] From Val di Non, we recommend you reach the Brenta Mountain Group from Rifugio Peller above Cles or by entering Val di Tovel. is thermodynamically favorable, with a Gibbs free energy of about -2.2 kcal/mol. In theory, ordinary seawater contains sufficient dissolved magnesium to cause dolomitization. However, because of the very slow rate of diffusion of ions in solid mineral grains at ordinary temperatures, the process can occur only by simultaneous dissolution of calcite and crystallization of dolomite. This in turn requires that large volumes of magnesium-bearing fluids are flushed through the pore space in the dolomitizing limestone. [24] Several processes have been proposed for dolomitization.

[1] The geological process of conversion of calcite to dolomite is known as dolomitization and any intermediate product is known as dolomitic limestone. [2] [3] The "dolomite problem" refers to the vast worldwide depositions of dolomite in the past geologic record in contrast to the limited amounts of dolomite formed in modern times. [4] [5] Recent research has revealed sulfate-reducing bacteria living in anoxic conditions precipitate dolomite which indicates that some past dolomite deposits may be due to microbial activity. [6] [7] Dolomite outcrops are recognized in the field by their softness (mineral dolomite has a Mohs hardness of 4 or less, well below common silicate minerals) and because dolomite bubbles feebly when a drop of dilute hydrochloric acid is dropped on it. This distinguishes dolomite from limestone, which is also soft but reacts vigorously with dilute hydrochloric acid. Dolomite usually weathers to a characteristic dull yellow-brown color due to the presence of ferrous iron. This is released and oxidized as the dolomite weathers. [14] Dolomite is usually granular in appearance, with a texture resembling grains of sugar. [15] The intense summer trip up some of the most fascinating and representative mountain faces in the Dolomites, such as the Brenta group, the Rosengarten, the Pale di San Martino, the Sella and, obvioulsy, the queen of them all, the Marmolada. The trip will be documented with photos, route topos and vide interviews with the first ascentionists.
