Re: [meteorite-list] FW: Rock identification??
Hi Mark Concrete would be my guess too. That being the case it should have a considerably lower specific gravity than a meteorite. I'm sure they won't mind if you dump it in water to test that! I recently had a guy see a new type of tektite fall from the sky. Amazingly it looked like a marble and even had yellow, red and blue frit on it. I had to tell the guy someone had probably thrown it at him Aubrey --- On Wed, 15/9/10, Mark Ford wrote: > From: Mark Ford > Subject: [meteorite-list] FW: Rock identification?? > To: Meteorite-list@meteoritecentral.com > Date: Wednesday, 15 September, 2010, 13:51 > > Hi, > > I was recently sent a rock, the accompanying story was that > it landed near someone with high velocity and was warm/hot > to the touch.

Re: [meteorite-list] FW: Rock identification??
yes, that had been my first thought, mortar or concrete, however it has numerous spherical glassy inclusions, and what look like larger melted black glassy features. Some of the spherules are very glassy clear red-brown some are opaque non glassy. I think I have just found one small metallic grain. Only thing is its not normal for concrete to have perfectly spherical glassy features? I've just uploaded another pic showing a spherule. The black inclusions in the pic are quite glassy looking, with vesicles in them. http://s911.photobucket.com/albums/ac315/meteoritemark/ Any help appreciated with this one, it's a bit strange!

It looks like a piece of cinderblock using ground up industrial slag as the aggregrate.

[meteorite-list] FW: Rock identification??
Hi, I was recently sent a rock, the accompanying story was that it landed near someone with high velocity and was warm/hot to the touch. (Normally this story rings alarm bells as meteorites are generally not known to be warm especially small ones), however upon looking at the rock, it appears to have chondrules (or chondrule like objects), but has no fusion crust. Its about 27mm x 19mm, and is very slightly attracted to a strong magnet, (enough for the rock to move when a magnet is put next to it. I can't explain what i'm seeing, these chondrule like features are near perfect spherules!, however I can't see any metal grains! Under mag there are numerous spherules, and other unidentifiable inclusions, the matrix is a grey to light beige colour. Anyone care to take a stab at what this is?
