Wow - this is making my head spin. It is my understanding that the O isotope data is necessary to show the relationship to the early earth-type rocks; it has to fall on the TFL. I would think this is necessary to prove a "pairing" to NWA 5400. Until then, it is not 100% certain. The fact that NWA 6292 IS paired to 5400 suggests that there could be more of this unique meteorite out there.
