The Mysterious Fukang Meteorite
When it slammed into the surface
of Earth, there was little sign of the beauty that lay inside, because cutting
the Fukang meteorite open yielded a breathtaking sight. Within the rock, translucent
golden crystals of a mineral called olivine gleamed among a silvery honeycomb
of nickel-iron. In China in 2000, the mysterious fukang meteorite, unearthed
believed to be some 4.5 billion years old, which is as ancient as Earth itself.
It is a pallasite, a type of meteorite with translucent golden crystals of a
mineral called olivine embedded in a silvery honeycomb of nickel-iron. It’s a
dazzling meteorite, and maybe the most spectacular extraterrestrial piece of
rock man has ever seen. This majestic Fukang meteorite was found by a hiker,
who had often stopped and had lunch on this giant rock, and he always
questioned what the metal and crystals were. Eventually he decided and took a
hammer and chisel and broke some pieces off, which he sent to the USA to
confirm that it was a meteorite.
The original meteorite weighted
just over a 1,000 kilogram, but the rock was so dazzling that everybody wanted
a piece of it. Since then it has been divided into dozens of thin slices and
auctioned or distributed around the world. Therefore, a total of 31 kilograms
of specimen is on deposit at University of Arizona. Marvin Kilgore of the
University of Arizona's Southwest Meteorite Centre holds the largest portion
weighing at 420 Kg. In Feb 2005 saw the Chinese space rock transported all the
way to the Tucson Gem and Mineral Show, in Tucson, Arizona. The U.S. lab claims
their polished slice of the original meteorite is the world's biggest pallasite
cross section, measuring 36in by 19in.
In 2008, this piece was expected
to fetch $2 million at an auction at Bonham's in New York, but unluckily, the
likely bidders were more impressed with a couple of pieces of
130-million-year-old fossilized dinosaur’s dung that day, which sold at more
than twice the estimate. According to Bonhams, pallasites are composed of
approximately 50 % olivine and peridot crystals and 50 cent nickel-iron, and
believed to be the relics of forming planets. They actually make up less than
one per cent of meteorites, and believed to originate from deep inside intact
meteors formed during the formation of the solar system about 4.5 billion years
ago and very few specimens are thought to have survived their descent through
Earth's atmosphere.
