Hi Greg St. and List,

What does it look like under a microscope? If you can see cleavages at 90?
it's probably a (weathered) pyroxene (fragment), otherwise it might be a
fragment of an oxidized olivine crystal.

Fred Beroud's A?fer 336 (L3.8; S3; W3) has a few of these conspicuous
orange chondrules. See, for example, Met.Bull. photos by "Meteoriteshow"
and by "Michel Girard".

The black seam may be melted troilite or it's a zoned olivine, i.e. the outer
rim is chemically different from the interior parts of the crystal.

Will send you a 16x (magnification) JPEG of such an
orange chondrule in my A?fer 336 slice in a private mail!


Best wishes,

Bernd
