Mineralogical and isotopic evidence suggests that these dolomites are of primary and abiotic origin. We infer that this dolomite layer might be the product of day and night temperature cycling of shallow lake water under local warming trend. This study provides evidence for abiotic dolomites forming at ambient temperature.

Dolomite takes its name from the Dolomite Alps, where it was first discovered. The term dolomite refers to both the calcium-magnesium carbonate mineral and to sedimentary rock formed predominantly of this mineral. The term dolostone was introduced in 1948 to avoid confusion between the two.

The mineral dolomite was probably first described by Carl Linnaeus in 1768. In 1791, it was described as a rock by the French naturalist and geologist Déodat Gratet de Dolomieu (1750–1801), first in buildings of the old city of Rome, and later as samples collected in the mountains now known as the Dolomite Alps of northern Italy.

Dolomite is formed by the replacement of the calcite ions by the magnesium ions. Depending upon the ratio of the Mg ions in the crystal lattice they have different names ( Figure 1 ). Modern dolomite formation has been found to occur under anaerobic conditions in supersaturated saline lagoons in Brazil.

Dolomite (also known as dolomite rock, dolostone or dolomitic rock) is a sedimentary carbonate rock that contains a high percentage of the mineral dolomite, CaMg(CO 3) 2.It occurs widely, often in association with limestone and evaporites, though it is less abundant than limestone and rare in Cenozoic rock beds (beds less than about 65 million years in age).

Re-analysis of finds made during excavations in the Tabun Cave (Israel) showed that one of the artifacts – a rounded dolomite stone – was a tool for polishing surfaces. This abrading tool, made about 350,000 years ago, pushed the birth date of grinding technology by 150,000 years. The Tabun Cave is located on the Carmel Range, in the ...

Dolomite types On the basis of the mode of formation, dolomites can broadly be divided into two groups: primary dolomite and secondary dolomite.2 Primary dolomite precipitate directly from aqueous solution, mostly at or near room temperature (20-35oC), with no CaCO 3 dissolution involved.3 However, dolomite can also form as a secondary phase

Dolomite is a common mineral containing calcium and magnesium, from the class of anhydrous carbonates, with the chemical composition CaMg (CO 3) 2. Origin (local): worldwide, often together with calcium carbonate (CaCO 3 ) Processing method: …

Bacterial mediation was invoked to solve the "dolomite problem", i.e. the inability to precipitate dolomite at ambient temperatures; the topic of the origin of dolomite formation is still being hotly debated (Liu et al., 2019; Ahm et al., 2019; Gregg et al., 2015). Other models invoke a primary or secondary (diagenetic) origin for dolomite.

Dolomite is formed by the replacement of the calcite ions by the magnesium ions. Depending upon the ratio of the Mg ions in the crystal lattice they have different names (Figure 1).
