Hi MikeG and All:

The iron might be from L6 if it turns out that the few silicates in it
(olivine and pyroxenes) have L6 geochem. You see that in the H-metal
from Yucca. Of course large metal masses are probably not as commonly
associated with L. Also if you had oxygen isotopes of the silicate
inclusions from the iron or for that matter oxygen isotopes of the
lithologies that seem to be more like achondrite, you could start to
sort out if it is all from the same meteoroid.
