Oog. I agree with Bernd; classification is currently a mess. We discussed
this a couple of years ago, but it seems any clarifications are very slow to
work their way into the literature. Has the NomCom issued any official
bulletins on this?
Best!
Tracy latimer
Those 1998 remarks still hold true, except for one thing... we've mostly
weeded out the classifications that used a slash for breccias. There
are still some in the MetBull database, probably, but mostly they're
fixed. Breccias are still a complete mess and nothing has changed.

Backing up and extending what Alan said, in current usage, a slash means
one of two things: 1) there are properties of this meteorite that are
intermediate or transitional between the two classes, or 2) The

John Wasson and I classified some meteorites as L/LL because we were
uncertain of their proper classification. Typical for these meteories, some
properties indicate L, some indicate LL, and some could be truly

Bernd, Alan, and List,
Thank you both for the diplomatic and informative responses. While we're on
the subject, might one of you (or anyone else) expand on, say, the L/LL6
classification designation? Holbrook was recently moved from an L6 to such
a classification, and I have a few others in my co

The general supposition is that all L chondrites come from one parent body,
that H chondrites come from another, etc. We don't know this to be strictly
true, but there is evidence that it is broadly true. For example, about

Hi Jeff, others,

But Dave’s question is in so far justified as there are several exceptional
