Hi List! I thought I would share some oriented stones from my UNWA box.
Here are 3 unclassified stones. The biggest I call the "Briquette" because it's shape reminds me of a charcoal briquette. (Cosmic Kingsford?) It weighs 90 grams and has many chondrules visible on the surface. There is just enough crust on it remaining to reveal the delicate flowlines radiating away from the leading face and towards the broken backside. It's a pity this stone arrived to me broken - it would have been nice to have the bubbly backside, instead there is a portion of the backside and a remnant of rollover lip - the rest is exposed matrix that is coated with wind polished desert varnish. 90 gram oriented briquette profile view with flowlines - http://i268.photobucket.com/albums/jj24/Meteoritethrower/Meteorites/oriented/flowlines-biscuit.jpg Another view of the briquette - http://i268.photobucket.com/albums/jj24/Meteoritethrower/Meteorites/oriented/oriented-biscuit-1.jpg Notice the plentiful chondrules - http://i268.photobucket.com/albums/jj24/Meteoritethrower/Meteorites/oriented/oriented-biscuit-a.jpg The second stone is a tiny bullet or mushroom shape. It has a prominent rollover lip and bubbly backside texture. Any traces of flowlines on the leading face or edge have been removed by weathering. Some fine rivulets are just visible on the backside, but they don't come out well in photos and are better seen with a loupe. This unclassified stone weighs 4.15 grams. Tiny bullet - http://i268.photobucket.com/albums/jj24/Meteoritethrower/Meteorites/oriented/bullet-side.jpg Bullet leading face - http://i268.photobucket.com/albums/jj24/Meteoritethrower/Meteorites/oriented/bullet-front.jpg Bullet backside - http://i268.photobucket.com/albums/jj24/Meteoritethrower/Meteorites/oriented/bullet-rear.jpg Lastly, I have an unclassified heat shield stone. This stone weighs 16 grams and has a classic "bubbly" backside, partial rollover rim, and faint remnants of flowlines near the lip. Heatshield leading face - http://i268.photobucket.com/albums/jj24/Meteoritethrower/Meteorites/oriented/shield-front.jpg Heatshield backside - http://i268.photobucket.com/albums/jj24/Meteoritethrower/Meteorites/oriented/shield-rear-2.jpg The 90-gram briquette is a keeper, but I would trade the 2 smaller stones if the offer is right. If anyone is interested, contact me offlist. Regards and clear skies, MikeG -- .........................................................
