Abstract Dolomite [CaMg (CO3) 2] forms in numerous geological settings, usually as a
diagenetic replacement of limestone, and is an important component of petroleum reservoir …

Over the past century a number of models have been developed to explain the vast
stratigraphic distribution of authigenic dolomite. These models include hydrogeological …

Authigenic carbonates recovered from two newly discovered active cold seeps on the
northwestern slope of the South China Sea have been studied using petrography …

An experimental study was conducted to determine oxygen and carbon isotope fractionation
factors in the system dolomite–water–CO 2 at 80–350 and 100–250° C, respectively, by …

Marine authigenic carbonates form shallow-water microbialites, mud mounds, and
hydrocarbon-seep deposits and contain appreciable amounts of trace elements that yield …

Although the mineral dolomite is abundant in ancient low-temperature sedimentary systems,
it is scarce in modern systems below 50° C. Chemical mechanism (s) enhancing its …

Carbonates represent major sedimentary rocks in on the continental and oceanic crust of
Earth and are often closely related to microbial activities. However, the origin of magnesium …

The geological factors controlling gas release from Arctic deep-water gas reservoirs through
seabed methane seeps are poorly constrained. This is partly due to limited data on the …

Some species of sulphate‐reducing bacteria (SRB) are known to mediate the formation of
dolomite and Mg‐calcite. However, their exact role in the mineralization process remains …

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 …
