[meteorite-list] Ad - Nice Unclassified Hand-Specimens, Gao Slices, Howardite Slice, La Criolla, & Low-Numbered Early NWA's
Greetings Collectors and Listees! I have some new specimens available, including some nice uNWA stony meteorites that are good hand specimens - these aren't all weathered up and covered in caliche. And they don't have an ugly side hiding away from the camera. All are covered in a glossy, wind-polished, desert varnish. They have that nice dark patina and some have patches of remnant fusion crust. These are mostly H-chondrites, so they are strongly attracted to a magnet. These are great to pass around as teaching or outreach props. Sizes range from about 15 grams up to 80+ grams. I also bulk lots of small stones available in 100g lots and larger. http://www.galactic-stone.com/products/nwa-unclassified Don't forget to use coupon code "metlist" at checkout for 20% off your entire order. :) I have some very nice little Gao Guenie slices. These are have a complete ring of fusion crust around the edges and nice flat cut faces that show tons of metal fleck and a fresh matrix. These are thumbnail-sized specimens that come in a labelled 1.25" gemjar. http://www.galactic-stone.com/product/gao-guenie--witnessed-hammer-fall--h5-chondrite-crusted-slices I have one polished part-slice of La Criolla (witnessed fall 1985). It weighs .5 gram and it has been polished to 1500 grit. It shows a black shock vein, metal fleck, and a beautiful matrix for a small piece. This is the only one I have - http://www.galactic-stone.com/product/la-criolla--l6-chondrite-witnessed-fall-argentina-1985-polish-slice One polished slice of NWA 2696 howardite available.

Re: [meteorite-list] Rosetta Flyby of Asteroid 21 Lutetia
Hi Sterling: But remember, that the M classification is based on is visible spectrum. Overall, it would have to have a relatively featureless visible spectrum that is redder than yur "typical" C-class asteroid. However, I think that there here been more detailed observations that show that there may be C-type patches on its surface. So, we may be looking at an M asteroid with carbonaceous patches on its surface from impacts. While I do not have access to the paper, I think that these observations are not consistent with the opposite: a carbonaceous surface with impact features that expose the metallic core of the asteroid. Guess we will know soon. I am still concerned with the high density. Even Vesta is only 3.5 grams/cc.
