C: Quantum: Wassonita, new mineral

Wassonita, new mineral discovered by NASA Posted: April 7, 2011 9:09 a.m. PDT NASA, in collaboration with researchers from the United States South Korea and Japan, has found a new mineral called wassonita one of the most historic meteorites recovered from Antarctica in December 1969. The new mineral was discovered in the enstatite chondrite meteorite Yamato forming 691. The meteorite was discovered the same year as other remarkable meteorite, Allende and Murchison, in which samples obtvuieron collected by the Apollo moon. The study of meteorites helps define our understanding of the formation and history of the solar system. The meteorite Yamato 691 can probably be caused by an asteroid that orbits between Mars and Jupiter. The wassonita is among the smallest but most important minerals identified in the sample, which dates back 4,500 million years ago. The research team led by NASA scientist Keiko Nakamura, mineral added to the list of the 4,500 officially recognized by the International Mineralogical Association. Wassonita (Wassonite). "The wassonita is a mineral consisting of only two elements: sulfur and titanium, however, has a unique crystalline structure that has not previously been observed in nature," said Nakamura-Messenger. In 1969, members of the Japanese Antarctic Research Expedition found nine meteorites on blue ice field of the Yamato Mountains in Antarctica. This was the first significant recovery of Antarctic meteorites and samples of different types represented. As a result, the United States and Japan conducted a systematic follow-up search for meteorites in Antarctica, in which recovered more than 40,000 specimens, including lunar and Martian meteorites extremely rare. The researchers found additional unknown minerals surrounded by wassonita being investigated. This mineral is less than a hundredth the thickness of a human hair. It would have been impossible to discover without a transmission electron microscope at NASA, which is able to isolate wassonita grains and their chemical composition and atomic structure. The meteorite Yamato 691.
The name of the new mineral was approved by the Mineralogical Association International. Honor John T. Wasson, a professor at the University of California at Los Angeles (UCLA). Wasson is known for its research achievements and the impact of meteorites, including the use of neutron activation data for the classification of meteorites and the formulation of models for the chemical composition of chondrites. "Meteorites and minerals in it, are windows to the formation of our solar system," said Lindsay Keller, a space scientist at NASA's Johnson Center in Houston. Keller is the co-discoverer and a principal investigator of the microscope used to analyze the crystals wassonita. "Through these studies we learn about existing conditions and processes that were taking place then. "

Quantum says:
The Yamato 691 (Y-691) is a meteorite 4.5 billion years old, which was discovered by members of the Japan Research Expedition in Antarctica Yamato Mountains, on December 21, 1969. 691 Yamato was one of nine samples of meteorites identified by the Japanese group and subsequently was studied at the Max Planck Institute for Chemistry in Mainz, Germany. this meteorite was found in the following minerals: * Troilite * Spinel * Diopside Augite
* * * pigeonite
enstatite Albita
* * * Iron Nepheline Olivine
* * Wassonite - recently discovered in April , 2011 Related Topics:
