Mike, Andy, Jim,

I don't have bias one way or another in the case of Katol, but looking
at the data in the write-up this is a clear-cut L6 chondrite -- no
ambiguity. There are chondrules albeit highly equilbrated, the
olivines are L6, the pyroxenes are L6, the oxygen isotopes are
L-chondrite. If there were no chondrules, high Wo and OC-type olivine
and pyroxene, then one could make the case for type 7. I'm just going
by the numbers given in the write-up, I haven't looked at this beyond
a quick glance in hand specimen, not an achondrite -- period.
