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

Although biomineralization of CaCO 3 is widespread in Bacteria and Archaea, the molecular
mechanisms involved in this process remain less known than those used by Eukaryotes. A …

Geological evidence indicates that grounded ice sheets reached sea level at all latitudes
during two long-lived Cryogenian (58 and≥ 5 My) glaciations. Combined uranium-lead and …

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 …

针对白云岩成因, 原生白云石沉淀, 白云岩孔隙成因等问题, 在前人认识的基础上,
补充四川和塔里木盆地典型案例的岩石学和地球化学特征分析工作, 取得3 项进展: ① …

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 …

The hydrated Mg-carbonate mineral, hydromagnesite [Mg 5 (CO 3) 4 (OH) 2· 4H 2 O],
precipitates within mine tailings at the Mount Keith Nickel Mine, Western Australia as a direct …

Past studies have revealed the important roles of certain types of microbes in precipitating
dolomite in coastal hypersaline lakes and lagoons, and marine sediments, however, it is still …

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 …

The direct crystallization of dolomite from an aqueous solution at temperatures between 60-
220° C was followed in situ through time-resolved synchrotron-based energy-dispersive X …
