While scientists remain uncertain exactly how the mineral dolomite is formed, an international team of researchers say that they have discovered that the process can be facilitated by bacteria. According to a recent press release jointly issued Monday by the Cluster of Excellence "The Future Ocean" and GEOMAR | Helmholtz Centre for Ocean Research Kiel, the mineral is primarily formed in extreme ecosystems like lakes and lagoons with high salinity. The exact process behind dolomite's...

Finds that rocks used as key geologic evidence were formed deep within Earth millions of years after the ice age ended There's a theory about how the Marinoan ice age"”also known as the "Snowball Earth" ice age because of its extreme low temperatures"”came to an abrupt end some 600 million years ago. It has to do with large amounts of methane, a strong greenhouse gas, bubbling up through ocean sediments and from beneath the permafrost and heating the atmosphere. The main physical...

Gossan Resources Limited (TSX VENTURE: GSS)(FRANKFURT/FREIVERKEHR XETRA:GSR) has received a final National Instrument 43-101 Report that establishes a substantial resource of high purity dolomite at its Inwood Magnesium Project. The resource estimate focuses on the flat lying Fisher Branch dolomite formation which outcrops on the Inwood Property with little or no overburden and averages a true thickness of about 12 metres. Gossan has initiated preliminary site and infrastructure planning for...

Dolomite is a mineral (formula CaMg(CO3)2) consisting of a calcium magnesium carbonate found in crystals and in beds as dolostone. A pure form of dolostone would be rare, however; it usually intergrades with limestone and is referred to as dolomitic limestone, or in old U. S. geologic literature as magnesian limestone. Dolomite has physical properties similar to those of the mineral calcite, but is less soluble in hydrochloric acid. There is uncertainty as to the cause of its formation,...

Limestone is a sedimentary rock composed of the mineral calcite (calcium carbonate). The primary source of this calcite is usually marine organisms. These organisms secrete shells that settle out of the water column and are deposited on ocean floors as pelagic ooze (see lysocline for information on calcite dissolution). Secondary calcite may also be deposited by supersaturated meteoric waters (groundwater that precipitates the material in caves). This produces speleothems such as stalagmites...
