Latest Carbonate minerals Stories
Study shows calcium carbonate takes multiple, simultaneous roads to different minerals, provides insight into trapping carbon dioxide in underground rock.
Can an abandoned mine help with the fight against global warming? Researchers from Stanford University think so. They have been using an abandoned mine to gain new insights on how to permanently entomb greenhouse gas emissions inside the Earth.
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.
The first day of spring brought record high temperatures across the northern part of the United States, while much of the Southwest was digging out from a record-breaking spring snowstorm.
A team of German scientists recently decoded the molecular structure of the unusually sturdy spines of sea urchins, a discovery that they believe could eventually prove useful in helping engineers construct stronger, more stable buildings.
Researchers from Japan say they have discovered vast deposits of rare earth minerals on the sea floor, minerals that are in high demand and used for modern gadgets and computers.
LONDON, September 13, 2010 /PRNewswire/ -- - Soda Ash: Market Outlook to 2015 (10th edition, 2010) Global consumption of soda ash fell by 7.6% in 2009 to 44Mt, following growth of 4.2%py between 2000 and 2008.
Which came first: the chicken or the egg? It is an age old question that has spurred on many a debate, but now a group of scientists might actually be close to having an answer.
Many scientists currently think at least 5 percent of humanity's carbon footprint comes from the concrete industry, both from energy use and the carbon dioxide (CO2) byproduct from the production of cement, one of concrete's principal components.
Sea urchins dig themselves hiding holes in the limestone of the ocean floor using teeth that donâ€™t go blunt.
Aragonite is a polymorph of the mineral calcite, both having the chemical composition CaCO3. Its structure differs from calcite and leads to a different crystal shape, an orthorhombic system with acicular crystals. By repeated twinning pseudo-hexagonal forms result. It may be columnar or fibrous, occasionally in branching stalactitic forms called flos-ferri (flowers of iron) from their association with the ores at the Carthinian iron mines. The type location for aragonite is Molina de...
Aurichalcite is a mineral, usually found as a secondary mineral in copper and zinc deposits. Its chemical formula is (Zn,Cu)5(CO3)2(OH)6. The name probably originates from the Greek oreichalchos meaning "mountain copper".
Azurite is a carbonate mineral with chemical composition Cu3(CO3)2(OH)2, (copper carbonate hydroxide). Azurite is often found in association with the green mineral malachite as a result of the weathering and oxidation of copper sulfide minerals. The name azurite comes from the Arabic word for blue. Azurite is used in jewelry and also collected as a beautiful mineral specimen. Use as a pigment Azurite has been used as a blue mineral pigment for centuries. It was formerly known as...
he mineral calcite is a calcium carbonate corresponding to the formula CaCO3 and is one of the most widely distributed minerals on the Earth's surface. It is a common constituent of sedimentary rocks, limestone in particular. It is also the primary mineral in metamorphic marble. It also occurs as a vein mineral in deposits from hot springs, and also occurs in caverns as stalactites and stalagmites. Calcite is often the primary constituent of the shells of marine organisms (e.g. plankton,...
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,...
