Hi List,

I was looking at Norites recently, and I came across the only
lunar-origin Norite, the lunaite NWA 773. I had no knowledge of NWA
773 prior to stumbling across it's Noritic connection.

The visual similarities between lunar norite and Vestan norite are
apparent. I am assuming the major differences are noted in chemistry.
Do lunar and Vestan norites share any other characteristics that might
blur the line between their respective parent bodies? In other words,
are these two types of norites so closely related that their may be
some room for reconsideration when it comes to their parent body
origins? (i.e., possible they came from the same body, or a noritic
body impact on the parent, etc)

Best regards,

MikeG
