KurtS Pillar of the Community United States 5318 Posts	Posted 08/03/2008 9:03 pm Here's an interesting bit of trivia I heard today: the older nickel-based coinage, whose source is the Sudbury mining region, most likely originated from a 9km wide asteroid, striking the area some 1.87 billion years ago. So if you've always wanted to own something from space, look no further than your pocket change. More trivia on the Sudbury asteroid strike Report this Post to the Staff

According to current theories, most of the Earth's nickel sunk straight down to the core shortly after the planet's formation. The only ways to get deposits of nickel on the surface are by external delivery (ie meteorites) and by deep-welling volcanic activity. Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis Report this Post to the Staff
KurtS Pillar of the Community United States 5318 Posts	Posted 08/04/2008 12:53 pm Well, ultimately I suppose every raw element on this planet was from "out there". Take it as you you will...I just thought it an interesting explanation for Sudbury's nickel deposits. Edited by KurtS 08/04/2008 12:57 pm Report this Post to the Staff

KurtS Pillar of the Community United States 5318 Posts	Posted 08/04/2008 7:18 pm Yes...and I hope I don't get motion sickness thinking about that! I suppose it's just me, but I've always wondered about the Platinum-group deposits at Sudbury and the impacts in that region. I found it very interesting how there is a correlation--basically the gist of this post. Edited by KurtS 08/04/2008 7:27 pm Report this Post to the Staff
