Latest Aragonite Stories
Sally sees seashells down by the seashore. (Say that 5 times fast.) Sally never knew why seashells' minerals (calcium carbonate) could form two different compounds until now.
Study shows calcium carbonate takes multiple, simultaneous roads to different minerals, provides insight into trapping carbon dioxide in underground rock.
Nearly one-third of CO2 emissions due to human activities enters the world's oceans.
Since the beginning of the Industrial Revolution, the concentration of carbon dioxide in the atmosphere has been rising due to the burning of fossil fuels.
Fossil land snail shells found in ancient soils on the subtropical eastern Canary Islands show that the Spanish archipelago off the northwest coast of Africa has become progressively drier over the past 50,000 years.
While the shiny material of pearls and abalone shells has long been prized for its iridescence and aesthetic value in jewelry and decorations, scientists admire mother-of-pearl for other physical properties as well.
Blue Coral, (Heliopora coerulea), is a species of coral in the Helioporidae family. It is commonly found in shallow coral reefs and is found extensively throughout the Indo-Pacific including the Ryukyu Islands in southwest Japan, the Coral Sea in northeast Australia, and American Samoa. The largest known blue coral colony in the world is off Ishigaki Island of the Yaeyama Islands in southwest Japan. This is the only known Octocoral known to produce a massive skeleton. The skeleton is...
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...
