[meteorite-list] Black inclusions in NWA R-Chondrites?

[Jeff Kuyken]

G'day,

I'm hoping someone may know of an abstract/personal/web info on the black
(xenolithic?) inclusions found in some of the NWA R-Chondrites? Here is an
example:

Any info would be appreciated either on or off-list.

Thanks,

Jeff
