| Tests puts age of Russian meteorite at 4.56 billion years
CHELYABINSK, Russia,[url=http://www.christianslouboutinsales.com]Christian Louboutin Outlet Online[/url], Oct. 7 () -- The meteorite that exploded over a Russian city in February was around 4.56 billion years old, as old as the Solar System itself,[url=http://www.christianslouboutinsales.com]Christian Louboutin Pigalle[/url], a scientist says.Mikhail Marov of the Vernadsky Institute of Geochemistry and Analytical Chemistry said the age of the so-called Chelyabinsk meteor was determined by a technique called radiometric dating, observing the amount of radioactive isotopes and their decay byproducts in the meteorite."The age of the Chelyabinsk meteorite -- 4.56 billion years -- almost coincides with the age of our solar system," Maroz said. "This means that we have encountered the so-called 'matter of creation.'""They [meteorites] hold the history of the processes that took place in the earliest period of the solar system's history."The scientists said the meteor was typical in its makeup, being a chondrite -- a stony, non-metallic meteorite.The original meteor, which exploded above city of Chelyabinsk on Feb. 15, is estimated to have weighed about 10,[url=http://www.christianslouboutinsales.com]Christian Louboutin Black[/url],000 tons and measured about 56 feet in diameter.When it exploded it injured about 1,500 people, most of them hurt by flying glass shattered by the blast's shock wave. |
