Hi Bernd and List, That's funny you mention that because Bob King also raised the possibility of phyllosilicates. I took some more photos of the specimen that show a better representation of what the specimen looks like. You can also see a distinct boundary line between the typical NWA 2086 lithology (darker matrix) and the strange "lighter colored" lithology that the majority of this stone has. One area near the end shows the type of matrix we expect from NWA 2086.
The brown inclusion does not show any features under it or through it, except in one small spot where two chondrules appear to be immersed in it, while the rest of the inclusion flows around the chondrules like a river flows around islands. http://i268.photobucket.com/albums/jj24/Meteoritethrower/endcut-519-a.jpg http://i268.photobucket.com/albums/jj24/Meteoritethrower/endcut-326-1.jpg http://i268.photobucket.com/albums/jj24/Meteoritethrower/2086-slice-weird-1.jpg Best regards, MikeG ------------------------------------------------------------ Mike Gilmer - Galactic Stone & Ironworks Meteorites http://www.galactic-stone.com http://www.facebook.com/galacticstone ------------------------------------------------------------ On 10 Aug 2010 15:21:51 UT, [email protected] <[email protected]> wrote: > http://i268.photobucket.com/albums/jj24/Meteoritethrower/2086-inclusion.jpg > > Hello All, > > Michael G. wrote: > > "So I am thinking that there must have been a surface fracture that extended > down into > the interior of the stone.
