Good evening, all.

Can someone please help me out with an explanation?

In looking at the Met Bul classifications of the "pairings" we have:

NWA 773, Lunar cumulate olivine norite with regolith breccia
NWA 2700 Classification pending
NWA 2727 Lunar mare basalt/gabbro breccia
NWA 2977 Lunar gabbro
NWA 3160 Lunar mare basalt breccia
NWA 3333 Classification pending

To my military mind, it seems to me that the classifications of the above
Lunars are divergent enough to wonder how they could be paired. If they are
truely paired, shouldn't the original classifications been the same or
closer?

Thanks,

Dave
