Description

Yes, of course you can. There are many facilities that offer hospitality to tourists visiting the Dolomites, such as rifugi ( mountain huts). These facilities are situated high up in the mountains and are organised in such a way as to accommodate mountain climbers and hikers. Obviously, they don’t have all the facilities of a traditional hotel, but there is no comparison to waking up in the heart of the Dolomites! The huts are usually open from 20 June to 20 September, but these dates can change according to the weather conditions. Some advice: if you decide to sleep in a mountain hut, take a sleeping bag or a sleeping bag liner with you, as in the CAI-run huts it is obligatory to have them!

Most dolomite was formed as a magnesium replacement of limestone or of lime mud before lithification. [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]Machel, Hans G. (2004). "Concepts and models of dolomitization: a critical reappraisal". Geological Society, London, Special Publications. 235 (1): 7–63. Bibcode: 2004GSLSP.235....7M. doi: 10.1144/GSL.SP.2004.235.01.02. S2CID 131159219. In Seville, on 26 June, 2009, the World Heritage Committee inscribed the Dolomites in the World Heritage List, citing the beauty of their unique landscape and geological features.

A number of long-distance footpaths traverse the Dolomites. They are called alte vie (German: Dolomiten Höhenwege – high paths), and are numbered 1 to 10. The trails take about a week to walk, and are served by numerous rifugi (huts). The first and the most renowned is the Alta Via 1. Radiocarbon dating has been used in the Alta Badia region to demonstrate a connection between landslide activity and climate change. [7] Geography [ edit ] Dolomite is supersaturated in normal seawater by a factor of greater than ten, but dolomite is not seen to precipitate in the oceans. Likewise, geologists have not been successful at precipitating dolomite from seawater at normal temperatures and pressures in laboratory experiments. This is likely due to a very high activation energy for nucleating crystals of dolomite. [32] It is possible that microorganisms are capable of precipitating primary dolomite. [7] This was first demonstrated in samples collected at Lagoa Vermelha, Brazil [6] in association with sulfate-reducing bacteria ( Desulfovibrio), leading to the hypothesis that sulfate ion inhibits dolomite nucleation. Later laboratory experiments suggest bacteria can precipitate dolomite independently of the sulfate concentration. [36] With time other pathways of interaction between microbial activity and dolomite formation have been added to the discord regarding their role in modulation and generation of polysaccharides, [37] manganese [38] [39] and zinc [40] within the porewater. Meanwhile, a contrary view held by other researchers is that microorganisms precipitate only high-magnesium calcite but leave open the question of whether this can lead to precipitation of dolomite. [41] Dedolomitization [ edit ] Highest peak: Mt. Marmolada (3,342 m a.s.l.), first ascent on August 3, 1802, by Don Giovanni Costadedòi, Don Giuseppe Terza and Don Tommaso Pezzei Another model is the mixing-zone or Dorag model, in which meteoric water mixes with seawater already present in the pore space, increasing the chemical activity of magnesium relative to calcium and causing dolomitization. The formation of Pleistocene dolomite reefs in Jamaica has been attributed to this process. However, this model has been heavily criticized, [26] with one 2004 review paper describing it bluntly as "a myth". [27] A 2021 paper argued that the mixing zone serves as domain of intense microbial activity which promotes dolomitization. [28]
