April Flowers for redOrbit.com - Your Universe Online 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. The team has spent two years trying to unravel a geological mystery at the Red Mountain mine, located about 70 miles east of the campus. Some of the world's largest veins of pure magnesium...

Bacteria Plays Role In Formation Of Dolomite
2012-06-08 05:37:32

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...

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. The weather, it seems, has gone topsy-turvy. Are the phenomena related? Are climate changes in one part of the world felt half a world away? To understand the present, scientists look for ways to unlock information about past climate hidden in the fossil record. A team of scientists led by Syracuse...

Structure Of Tough Sea Urchin Spines May Inspire Engineers
2012-02-16 14:10:27

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. Biologists have long known that the spines of the globular little marine animals are made of the compound calcium carbonate, a chemical commonly found in the shells of various invertebrates, not to mention egg shells, calcium supplements and the antacids...

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. Geologists estimate that there are about a 100 billion tons of the rare elements in the mud of the Pacific Ocean floor, BBC News is reporting. If recovering these minerals from the sea floor proves to be commercially viable, the discovery of these deposits could challenge the dominance of China's production of these...

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. Consumers in the glass industry, which accounts for 53% of total demand, scaled back purchases during the global economic downturn. The fall was compounded by lower detergent and chemical output, the other major end-uses for soda ash. Emerging economies have been the...

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. Using cutting-edge technology, researchers from the Universities of Sheffield and Warwick in England believe that they have discovered the answer by studying eggshells. Scientists had long theorized that a chicken protein known as ovocledidin-17 (OC-17) played a crucial role in the formation of an egg's shell, but...

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.Yet several studies have shown that small quantities of CO2 later reabsorb into concrete, even decades after it is emplaced, when elements of the material combine with CO2 to form calcite.A study appearing in the June 2009 Journal of Environmental...

Sea urchins dig themselves hiding holes in the limestone of the ocean floor using teeth that don't go blunt. Weizmann Institute scientists have now revealed their secrets, which might give engineers insights into creating ever-sharp tools or mechanical parts. The urchins dig holes to fit their globular bodies using their five teeth, which, like those of rodents, are ground down at the tip but continue to grow on the other end throughout the animals' lives. The amazing part, however, is that...

The precise timing of the origin of life on Earth and the changes in life during the past 4.5 billion years has been a subject of great controversy for the past century. The principal indicator of the amount of organic carbon produced by biological activity traditionally used is the ratio of the less abundant isotope of carbon, 13C, to the more abundant isotope, 12C. As plants preferentially incorporate 12C, during periods of high production of organic material the 13C/12C ratio of carbonate...

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,...

  • A somewhat riotous parade, accompanied with the blowing of tin horns, and other discordant noises; also, a burlesque serenade; a charivari.
'Callithump' is a back-formation of 'callithumpian,' a 'fanciful formation' according to the Oxford English Dictionary. However, the English Dialect Dictionary, says 'Gallithumpians' is a Dorset and Devon word from the 1790s that refers to 'a society of radical social reformers' or 'noisy disturbers of elections and meetings.'
