Hi Carl,
Spot on!
Question: How much material is required for the oxygen isotope testing???
When we were working on the H-Metal, the ICPMS-LA (Herd) tests completed
on the last one used less than 100 milli-grams.
And previous INAA (Actlabs) testing used 100 milli-grams. And, as you
know sample size was nill!
In either case, is not like you have to cut a third of it off. Not
sure about the OI tests.

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.
