Dolomite [CaMg(CO3)2] forms in numerous geological settings, usually as a diagenetic replacement of limestone, and is an important component of petroleum reservoir rocks, rocks hosting base metal deposits and fresh water aquifers. Dolomite is a rhombohedral carbonate with a structure consisting of an ordered arrangement of alternating layers of Ca2+ and Mg2+ cations interspersed with CO32− anion layers normal to the c‐axis. Dolomite has R3¯ symmetry, lower than the (CaCO3) R3¯c symmetry of… 
Comparisons on Mineralogy and Lithology between Paleozoic Marine and Lacustrine Dolostones, Northern China
Dolomite [CaMg(CO3)2], a common mineral in carbonate rocks, can be found in various geological settings from Precambrian to modern age, and is widely reported in almost all sedimentary and digenetic
The impact of Mg2+ ions on equilibration of Mg-Ca carbonates in groundwater and brines
Abstract At temperatures below 50 °C, the log10 (aMg2+/aCa2+) values in groundwater and brines, irrespective of their origin – either carbonaceous or siliceous rocks/sediments – cover the range
Nucleation and growth of Mg-bearing calcite in a shallow, calcareous lake
Reducing microenvironments promote incorporation of magnesium ions into authigenic carbonate forming at methane seeps: Constraints for dolomite formation
In part composed of Mg calcite and dolomite with a nearly continuous spectrum of MgCO3 contents, carbonates forming at marine methane seeps are ideal candidates to study the formation of early
Dolomite dissolution: An alternative diagenetic pathway for the formation of palygorskite clay
Palygorskite is a fibrous, magnesium‐bearing clay mineral commonly associated with Late Mesozoic and Early Cenozoic dolomites. The presence of palygorskite is thought to be indicative of warm,
High Magnesium Calcite and Dolomite composition carbonate in Amphiroa (Lithophyllaceae, Corallinales, Rhodophyta): further documentation of elevated Mg in Corallinales with climate change implications
TLDR
VHMC/dolomite is more stable than Mg‐calcite, and this may provide a competitive advantage for Amphiroa species as seawater pH declines, and further work is required to determine the metabolic controls on VHMC/.
Non‐classical crystallization of very high magnesium calcite and magnesite in the Coorong Lakes, Australia
The Coorong Lakes, South Australia, are one of the models for unravelling the ‘Dolomite Problem’. Critically, today only a few modern environments remain where large quantities of very high magnesium
