Hi Mike ,Thanks for the reply. With that many pairings
to Franconia from the north side and as Rob Matson has
pointed out that the Fayolite of Franconia is 17.6
compared to 25.1 in Buck Mountain Wash and the
Fayolite content of Jim Smallers Sacramento Wash OO5
ungrouped iron is 17.5, and as Jim Smaller pointed out
to me that Franconia and SW 005 both have rare
metallic copper, coupled with the preponderance of
irons being found on the north is a strong indication
that the irons were shed out of the Franconia
meteorite.
