DOLOMITE
The term dolomite refers both to a sedimentary carbonate rock and to the mineral from which the rock is primarily composed. Thus, we can say that the dolomite rock is a type of sedimentary carbonate rock made from the mineral dolomite, which is actually a calcium magnesium carbonate. Dolomite rock primarily forms through the process of dolomitization, i.e., metasomatism of limestone, where magnesium ions from seawater or underground water replace calcium ions in the crystal lattice of calcite or push calcite out of already solidified limestones, replacing it with dolomite. This process has led to the formation of huge amounts of dolomite rock, which builds large mountain ranges, such as the Alps, where dolomite deposits reach up to 2000 meters in thickness.
Dolomite is named after the French geologist Déodat de Dolomieu, who during his travels in the Tyrolean Alps observed a carbonate rock similar to limestone that, unlike limestone, does not react with diluted hydrochloric acid. Dolomieu published these observations in 1791 in the famous Journal de Physique. In addition to the mineral and rock, the name also refers to a mountain range in northeastern Italy, where a monument to Dolomieu was erected at the Cortina d'Ampezzo ski resort in the Dolomites. Interestingly, the 1956 Winter Olympics were held there, and the area is famous for being featured in films such as The Pink Panther (1963), For Your Eyes Only (1981), and Cliffhanger (1993).
However, records show that Belsazar Hacquet, a Carniolan physician of French descent who worked in the mining town of Idrija in Slovenia, had already distinguished dolomite rock from limestone, describing it in 1778 as "smelly stone" (lapis suillus, Stinkstein in German). Hacquet mentioned that the famous botanist Carl Linnaeus had discovered in 1768 that, unlike limestone, dolomite does not react with diluted hydrochloric acid. This discovery is attributed to Carl Linnaeus, the Swedish botanist known for introducing the binomial nomenclature of living organisms still used today.
