TORONTO.- The Royal Ontario Museum (ROM) has acquired the worlds largest piece of the Springwater pallasite, a rare and scientifically important meteorite that was first discovered near Springwater, Saskatchewan in 1931. The new discovery of the almost 53 kilogram (117 pound), 4.5-billion-year-old specimen was made in 2009 after a re-examination of the original fall site. There have only been three pallasite meteorites ever found within Canada: the Giroux in Manitoba, the Southampton in Ontario and the Springwater in Saskatchewan. With the addition of this acquisition, the ROM now houses all three main masses of known Canadian pallasite meteorites Pallasite meteorites provide scientists the unique opportunity to look billions of years into the past and examine material similar to what we infer is deep within our Earth, says Dr. Kim Tait, ROM Associate Curator of Mineralogy. Theyre invaluable research
