connorp Posted October 9, 2013 Share Posted October 9, 2013 This was sold to me as an unclassified end cut. I see evidence of fusion crust and there are nickel/iron specks inside. It feels unusually heavy for a rock of its size. It is attracted to a magnet. Only thing that gets me is a few tiny holes inside. I can't tell if they're vesicles or just holes from material knocked loose during cutting. Ideas? Quote Link to comment Share on other sites More sharing options...
Mikestang Posted October 9, 2013 Share Posted October 9, 2013 The photos are a little blurry. Does your camera have a macro setting? I'd also suggest taking pictures outside in direct sunlight. Quote Link to comment Share on other sites More sharing options...
connorp Posted October 10, 2013 Author Share Posted October 10, 2013 Ok, I will tomorrow. Just one question. I did the streak test and the rock had an almost reddish gray streak. It was not the thick any only appeared defined on some sides of it. It is very weathered. I have read in multiple credible places that extremely weathered meteorites can leave streaks. Is this true? As the rock passes all tests but this, and the streak doesn't look as defined or red as one would expect a hematite streak to be. Quote Link to comment Share on other sites More sharing options...
connorp Posted October 10, 2013 Author Share Posted October 10, 2013 Well I have confirmed it is an iron meteorite. After over an hour of acetone baths and vigorous filing, I whittled down the outside to find a completely iron meteorite. So the streaks were just from all the rust and debris on the outside. And as I grinded, the small holes disappeared, so I'll chock those up to remnants of the cutting. Thanks though. Quote Link to comment Share on other sites More sharing options...
newriverblake Posted October 10, 2013 Share Posted October 10, 2013 I am no expert but, from all the gold basins I have found I think it looks very promising. Quote Link to comment Share on other sites More sharing options...
connorp Posted October 10, 2013 Author Share Posted October 10, 2013 Thanks. I did some more baths and filing and I know believe it to be a mesosiderite as there is a lot of iron/nickel but not all iron/nickel. Quote Link to comment Share on other sites More sharing options...
Mikestang Posted October 10, 2013 Share Posted October 10, 2013 It's not an iron meteorite, nor is it a mesosiderite. If anything it is an ordinary chondrite. Quote Link to comment Share on other sites More sharing options...

fredmason Posted October 10, 2013 Share Posted October 10, 2013 whoever sold you that meteorite should know where it came from and the type...I agree with Mikestang...appears to be an ordinary Chondrite...fred Quote Link to comment Share on other sites More sharing options...
homefire Posted October 10, 2013 Share Posted October 10, 2013 LOL! From the Photo it looks like Pyrite to me. Quote Link to comment Share on other sites More sharing options...

Mikestang Posted October 12, 2013 Share Posted October 12, 2013 So the streaks were just from all the rust and debris on the outside.Yup, when you do a streak test you are supposed to make a window first, then streak the window so you are getting the inside of the rock.

frank c Posted October 14, 2013 Share Posted October 14, 2013 Looks like it could be an L to me from the pics. Does the background matrix have a greenish tint to it? That's what the pics make it look like. Quote Link to comment Share on other sites More sharing options...
connorp Posted October 15, 2013 Author Share Posted October 15, 2013 Nope. Some black patches of fusion crust, but the rest is light brown. Quote Link to comment Share on other sites More sharing options...
