Mike Busutil Posted May 28, 2012 Share Posted May 28, 2012 Hello,I found this while riding my dirt bike through a large sand dune area in Yuma Arizona (USA) , it stood out because it was the only rock I could see as far as I looked. It weighs 1 lb and is magnetic.Any thoughts on it?Thanks. Quote Link to comment Share on other sites More sharing options...

Troyball Posted May 29, 2012 Share Posted May 29, 2012 First thought is it is volcanic. You need to do a ceramic streak test and window the stone. Those two tests will tell you a lot about this rock.Troy Quote Link to comment Share on other sites More sharing options...
homefire Posted May 29, 2012 Share Posted May 29, 2012 Looks like the slage they use for Rail Road Float to me.Did you cut it? Quote Link to comment Share on other sites More sharing options...
Mikestang Posted May 29, 2012 Share Posted May 29, 2012 Meteorites do not look melted like that. Quote Link to comment Share on other sites More sharing options...
Mike Busutil Posted May 29, 2012 Author Share Posted May 29, 2012 Cut it? Just cut it in half or cut a piece off of it? Quote Link to comment Share on other sites More sharing options...
Troyball Posted May 29, 2012 Share Posted May 29, 2012 This is not a meteorite, but go ahead and window it, just for fun. Take a file and file one end to show you what the interior of the stone looks like. Troy Quote Link to comment Share on other sites More sharing options...

Au Seeker Posted May 29, 2012 Share Posted May 29, 2012 Mike, The "streak" test is rubbing the specimen on an unglazed piece of ceramic, i.e. a tile, the bottom ring on a coffee cup, or the underside of your toilet lid, the color of the streak on the ceramic or lack thereof will help determine what the item is, almost all minerals, rocks, certain metals, etc. will create a streak on the ceramic, you can also buy "Streak Test kits that have white and black ceramic plates in it, some specimens may leave a white or very light colored streak which would not be visible or hard to see on white ceramic, and the opposite with a black or dark colored streak.Generally most meteorites don't leave a streak.A "window" is filing or grinding a small spot on the specimen so you can see the interior of the specimen, this is most often done for helping in IDing some meteorites, instead of cutting the specimen.Skip Quote Link to comment Share on other sites More sharing options...

Goldfinger Posted June 1, 2012 Share Posted June 1, 2012 Mike-Sand dunes are great areas to look for meteorites. Keep looking and I think you'll be successful one of these days.Steve Quote Link to comment Share on other sites More sharing options...

Goldfinger Posted June 2, 2012 Share Posted June 2, 2012 Mike, read this article about blow outs. You may or may not have them in your area but worth looking for.http://issuu.com/theodoremediallc/docs/temerity_magazine_august_2011?mode=embed&layout=http%3A%2F%2Fskin.issuu.com%2Fv%2Fdark%2Flayout.xml&pageNumber=29Steve Quote Link to comment Share on other sites More sharing options...
