[meteorite-list] Kalahari lunar meteorite stones - photos

[Adam Hupe]

Maybe I should go through my meteorite-wrong pile
again.  I noticed they gave it a weathering grade of
1.  I thought metal had to be present in order to
qualify a weathering grade and that they are generally
not assigned to achondrites. The CRE age seems to be
no different than a rock that spent 300 years in the
desert. 

What makes this stone any different than a terrestrial
impactite?
