Hello Kai, You might be interested to know that your specimen is paired to NWA 2836, 2999, 3164, and 6291.
http://www.catchafallingstar.com/nwa4662.htm But I checked the Meteoritical Bulletin, and there are more pairings! NWA 3158, 4569, 4662, 4931, and possibly 4877 are all part of the same fall, apparently. And that's not me talking - that's NAU and the Meteoritical Bulletin! So your specimen is actually a piece of the second-largest angrite ever found, and is part of the only known angrite multiple-fall; the reported tkw of the fall is approximately 5 kilograms if you go by the bulletin (6kg if you include 4877), but there's probably a bit more out there. Beyond that, well - we've gone over NWA 2999 and its relatives quite a bit in the past few list messages on angrites. You can check out the paper that suggests they're from Mercury. It describes a stone that's paired to yours, so...kinda cool. http://www.lpi.usra.edu/meetings/lpsc2006/pdf/1344.pdf Best, Jason On Thu, Jul 22, 2010 at 5:34 AM, kai ke <[email protected]> wrote: > Hi Jason, > > I just bought a NWA 4662 Angrite.
