8 Dolomite enabled the preservation of fine microbial textures in some Archean and Proterozoic 9 marine microbialites, but has rarely done so during the Phanerozoic. Here, we report precipitation 10 of dolomite in anoxygenic photosynthetic biofilms grown under chemical conditions relevant for 11 Archean seawater. Ordered dolomite nucleates primarily on the surfaces of photosynthetic cells 12 when manganese(II) is also present, nanocrystals of disordered dolomite form on exopolymeric 13… 
A new model for silicification of cyanobacteria in Proterozoic tidal flats
TLDR
These experiments demonstrate that the exceptional silicification of benthic marine cyanobacteria analogous to the oldest diagnostic cyanobacterial fossils requires interactions among extracellular polymeric substances (EPS), photosynthetically induced pH changes, magnesium cations (Mg2+), and >70 ppm silica.
Modern dolomite formation caused by seasonal cycling of oxygenic phototrophs and anoxygenic phototrophs in a hypersaline sabkha.
TLDR
A modern dolomite forming environment is examined, and it is found that a cyclic shift in microbial community between cyanobacteria and anoxygenic phototrophs creates EPS suited to dolmite precipitation, which provides new context for the interpretation of dolOMite throughout Earth's history.
Preservation of Organic Carbon in Dolomitized Cambrian Stromatolites and Implications 1 for Microbial Biosignatures in Diagenetically Replaced Carbonate Rock
17 Stromatolites have been a major focus in the search for ancient microbial life, however, the 18 organic carbon biosignatures of dolomitized stromatolites have not yet been fully characterized 19
Light-driven anaerobic microbial oxidation of manganese
TLDR
Anoxygenic photosynthetic microorganisms can biomineralize manganese oxides without molecular oxygen being present and without high-potential photosynthesis reaction centres, which sheds doubt on proposed dates for the origins of oxygenic photosynthesis.
Microbial dolomite in culture experiment and natural environments: implication for dolomite genesis
Abstract The genesis of dolomite is a century-old mystery in sedimentology. The ‘microbial dolomite model’ proposed in recent years provides new insight into the study of dolomite genesis. However,
Anoxygenic phototrophs and the forgotten art of making dolomite
Dolomite [CaMg(CO3)2] is abundant in ancient rocks and rare in younger ones; why is unclear. Evidence is now emerging (Daye et al., 2019, p. 509 in this issue of Geology) that primitive microbes can
Systematic laboratory approach to produce Mg-rich carbonates at low temperature
Dolomite is a common Mg-rich carbonate in the geological record, but the mechanism of its formation remains unclear. At low temperature, the incorporation of magnesium ions into the carbonate
Searching for biosignatures in sedimentary rocks from early Earth and Mars
The recognition of past habitable environments on Mars has increased the urgency to understand biosignature preservation in and characterize analogues of these environments on Earth. In this Review,
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
