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 …

Widespread development of microbialites harbors a series of clues about microbial activity,
environmental condition, and aquatic chemistry. The Ediacaran-Cambrian transition draws …

A variety of Mg-, Na-and Ca-sulfates, including gypsum, and Mg-clays precipitate within the
microbial mats that developed seasonally in the hypersaline playa lake El Longar (Central …

Microbial biofilms and mats have long been studied for their role in mineral precipitation
reactions in natural environments. Scanning electron microscopy (SEM) is often used to …

The earliest evidence of life captured in lithified microbial mats (microbialites) predates the
onset of oxygen production and yet, modern oxygenic mats are often studied as analogs …

In sedimentary environments, clay and sand are segregated by hydrodynamic processes.
Yet, clay coats, thin clay envelopes lining sand grains, are abundant in modern and ancient …

Microorganisms are globally distributed but new evidence shows that the microbial structure
of their communities can vary due to geographical location and environmental parameters …
