Microbially catalyzed dolomite formation: from near-surface to burial
Over the past century a number of models have been developed to explain the vast
stratigraphic distribution of authigenic dolomite. These models include hydrogeological …

What do we really know about early diagenesis of non-marine carbonates?
Non-marine carbonate rocks including cave, spring, stream, calcrete and lacustrine-
palustrine sediments, are susceptible to early diagenetic processes. These can profoundly …

Carbonate and silicate biomineralization in a hypersaline microbial mat (Mesaieed sabkha, Qatar): Roles of bacteria, extracellular polymeric substances and viruses
In a modern peritidal microbial mat from Qatar, both biomediated carbonates and Mg‐rich
clay minerals (palygorskite) were identified. The mat, ca 5 cm thick, shows a clear lamination …

Experimental evidence for abiotic formation of low-temperature proto-dolomite facilitated by clay minerals
The origin of sedimentary dolomite is a subject of long-standing enigma that still awaits
resolution. Previous studies have shown that room temperature synthesis of abiotic dolomite …

Genesis mechanism and Mg isotope difference between the Sinian and Cambrian dolomites in Tarim Basin
G Zhu, X Li, T Li, L Zhou, Y Wu, B Shen… - Science China Earth …, 2023 - Springer
Dolomite genesis is a century-old mystery in sedimentology. To reveal the mechanism of
dolomite genesis, two core problems need to be addressed. The first is the origin and …

Modern dolomite formation caused by seasonal cycling of oxygenic phototrophs and anoxygenic phototrophs in a hypersaline sabkha
Abstract The “Dolomite Problem” has been a controversy for over a century, owing to
massive assemblages of low-temperature dolomite in ancient rocks with little dolomite …

High salinity facilitates dolomite precipitation mediated by Haloferax volcanii DS52
X Qiu, H Wang, Y Yao, Y Duan - Earth and Planetary Science Letters, 2017 - Elsevier
Although most modern dolomites occur in hypersaline environments, the effects of elevated
salinity on the microbial mediation of dolomite precipitation have not been fully evaluated …

Variability of blue carbon storage in arid evaporitic environment of two coastal Sabkhas or mudflats
Coastal Sabkhas are mudflats found in arid coastal regions that are located within the
supratidal zone when high rates of evaporation lead to high salinity. While evaporitic …

[HTML][HTML] Phanerozoic variation in dolomite abundance linked to oceanic anoxia
The abundance of dolomitic strata in the geological record contrasts with the general rarity of
locations where dolomite forms today, a discrepancy that has long posed a problem for their …

Calibration of the oxygen and clumped isotope thermometers for (proto-) dolomite based on synthetic and natural carbonates
Dolomite is a very common carbonate mineral in ancient sediments, but is rarely found in
modern environments. Because of the difficulties in precipitating dolomite in the laboratory at …
