Microbial mats are ecosystems that arguably greatly affected the conditions of the biosphere
on Earth through geological time. These laminated organosedimentary systems, which date …

Describing, characterizing and interpreting the nearly infinite variety of carbonate rocks are
conundrums–intricate and difficult problems having only conjectural answers–that have …

Deposits produced by microbial growth and metabolism have been important components of
carbonate sediments since the Archaean. Geologically best known in seas and lakes …

Reefs are an extraordinary natural phenomenon. Visible from outer space, coral reefs are
the largest biologically constructed features known; in close proximity their spectacular …

The main groups of organisms participating in the formation of benthic microbial carbonates
are bacteria, cyanobacteria and algae. Three main processes are involved in the formation …

Thrombolites and stromatolites are distinct types of microbial (cryptalgal) structures
characterized, respectively, by mesoscopic clotted and laminated internal fabrics. Although …

Calcification affects the sheath of some coccoid and filamentous cyanobacteria during their
life, under suitable environmental conditions. There is probably a link between sheath …

Secular variation in microbial carbonate abundance may be reflected by stromatolite
morphotype diversity and reefal microbial carbonate abundance. These datasets reveal long …

Aftermaths of mass extinctions have been thought to be characterized by relaxation of
ecological constraints, accompanied by increased prominence of opportunistic generalists …
