It's probably light green olivine that crystallized with other pre-solar nebular material, silicates in particular- some of which have no color hue. I've seen many different color hues in my Allende slice and the fascinating and sometimes perfect chondrules when observing them under an American Optical 1000x microscope- rotated down to 100x of course. There's a great book with a section on chondrules alone called (Brazilian Meteorites)and you can get it from: Bethany Sciences (Ron Farrell), New Haven ,CT. . He sold me my first meteorite, Allende, a 156gram 95% fusion crust and a 5gr. slice so that I could better see the chondrules. The whole chondrite has a 1/2"in. piece cracked off of it from impacting a widows porch roof. Scared her to death when the rest of the stones came in hypersonic and rained down on(Village Of Allende). Last told, she still has a 10kilo Allende "with a beautiful, undamaged, black skin" buried on her farm 2ft. down in a plastic trash bag. Imagine a slice off of a 10 kilo Allende , and all the calcium/aluminum and other inclusions, like Gold, Silver, Brass balls- sorry, meant chondrules:), lets not go back there, please! An (e.g.) from the book that I'm pretty sure some of us collectors of nebular fragmented accretions (meteorites), is the description of Chondrule Textures: 1-Porphyritic 2-Barred and Rimmed 3-Excentro-Radial and 4-Granular Porphyritic. It took me 3 years before I found out that Chondrules were formed by the "spontaneous crystallization of freely-floating highly-supercooled droplets of melt"- in my opinion the best description that everybody can visualize- not my description, I forget where I copied it from? The've found chondrules with tiny nickel/iron cores. Then you throw at your friends or family that the Earth is nothing but a MACRO -CHONDRULE and you've lost'em. Hey, I get excited about free-floating spheres, especially when they have names, you know what I mean? Sorry about the lengthy response Tom. It's 3:54AM here and I've been watching way too much War T.V. You can't help but get hooked on it!
