| Why this rock is probably not a meteorite:
The finder thought that this might be a chondritic meteorite because
of the round chondrule-like objects (~1-2 mm in diameter).
Chondrules do not stand out like this on the broken surface of a chondrite,
and it seems unlikely to us that they would stand out even on a highly
weathered chondrite. The grayish matrix looks like it could be
|What is it?
We suspect that the round things are o÷litiths - calcium carbonate
growths on sand grains or organic matter, which are common in some
limestones (o÷litic). The o÷litiths may now be silicified, which
would make them harder.

Addendum: Dr. Nicholas Gessler of UCLA saw this photo and told me
that sometimes chondrules do stand out from the matrix
and sent this remarkable photo
of a chondrule in a CV chondrite that he has in his collection (photo
by Adam and Greg Hupé).
