By NICOLE MACINTYRE The London Free Press (Canada) June 13, 2002 Amateur rock hound Carl Young has earned the ultimate bragging rights. But the modest Londoner says pure luck led to his discovery of one of the rarest meteorites in the world on the shores of Lake Huron. "The chances of finding one are almost the same as finding a snowball in . . .,"said Young, who spends his summers in the Owen Sound area. Young was searching for driftwood when he stumbled upon the 2.5-kilogram rock in April 2001. With his suspicions aroused by the unusually heavy weight of the rock, he turned to the experts at the University of Western Ontario. "I think there are probably hundreds of people that would have walked right by it," said earth sciences professor Neil MacRae, who was impressed by the rare find, which may be as much as 4.5 billion years old. The pallasite meteorite, one containing both metallic and silicate minerals, is the 52nd found in the world and the third in Canada. "When you're talking numbers that low, it's certainly significant scientifically," said MacRae. Scientists have a special interest in meteorites, he said, because they offer valuable information about the core of the Earth. Made of the same materials, meteorites help prove theories about a part of the Earth that is unreachable. It took more than a year to discover the meteorite's composition, which was vital in determining whether it had fallen elsewhere and been transported by humans or was a new fall. MacRae found the meteorite's chemical "signature" was similar to the famous Brenham pallasite meteorite that fell in Kansas in 1882. Pieces of that space rock have been sold around the world. But a chemical "fingerprint" of Young's meteorite completed by Stephen Kissin at Lakehead University proved the meteorite is unique and a new fall. "I'm glad it's finally settled . . . it was worth the wait," said Young, who has donated a section of the valuable rock to Western for display. In turn, the university will make the sample available for testing to researchers around the world, said MacRae. Young is working to have the meteorite officially registered with the Meteoritical Society Bulletin. Following a tradition to name a meteorite after the nearest post office, Young's find will be nicknamed the Southampton Pallasite. Received on Thu 13 Jun 2002 12:59:07 PM PDT |
