The lab data you (Carl) mention suggests only L, nothing more. No one's arguing with that. We had that data months ago.
As I understand it, not one chondrule was observed optically in Katol; they were found only when examining BSE images. This would have ruled out a chondritic classification prior to the widespread use of SEM's. And the fact that we're discussing this now is relevant; no other "type 6" chondrite has been metamorphosed to this extent (literally invisible chondrules, unless you have a multi-million dollar piece of equipment at your disposal). Since this meteorite doesn't texturally resemble any known L's, having been melted and slowly cooled to a poikilitic texture, deeming it an L6 is pigeonholing it. Larger-scale heterogeneities resulted in 140 gram iron meteorites and 200+ gram literally metallic-iron-free meteorites with glossy Ca-rich fusion crusts. Such things aren't usually glossed over when classifying a meteorite. It's just like calling Al Haggounia 001 an aubrite, EL6/7, or EL3. Just because you can justify a classification with a few parameters doesn't make it an accurate descriptor of a meteorite. Which of those classifications is best? EL3. Is it right? No. That stone doesn't texturally resemble any other (enstatite) chondrites of any kind. It's anomalous. Rather like Katol.
