Comment: Locality might be Morocco. You've heard the expression 'older than dirt'? Well, this really is! Chrondules were formed before the Earth coalesced out of the protoplanetary disk that surrounded the sun over 4.5 billion years or so ago. The little light colored spot magnified in the second picture is a CAI, a Calcium Aluminum rich Inclusion. It is even older, forming millions of years before the chrondule itself! Tucson - This meteorite is classified as a carbonaceous chondrite, (CV3. There were many fragments recovered, with a total known weight of only 780 grams. It is a beautiful meteorite, with sharp large multi-colored chondrules, and small CAI's. They represent some of the oldest material ever found and date back to the initial formation or beginning of our Solar System. http://tin.er.usgs.gov/meteor/metbull.php?code=17599
