Hello Martin and List,

Martin wrote: "I just measured the mega chondrule in my slice of Alfianello
Italy slice. It is 11mm x 8mm and almost dead center in the face, and pretty
much all alone."

Beautiful slice and wonderful chondrule with a nice-looking white rim! Is
it a "bleached" chondrule?

Martin inquired: "Is there really a 48mm chondrule in Djati-Pengilon?
Got a pic of it anywhere? Can a whole meteorite be a single chondrule?
Where did the list come from?"

The list comes from this article in Meteoritics:

Bridges J.C. et al. (1997) A survey of clasts and large chondrules
in ordinary chondrites (Meteoritics 32-3, 1997, 389-394).

The info on the 48 mm chondrule in Djati-Pengilon comes from
David Weir. He described it as ellipsoidal and he posted this when
we had a similar thread some years ago.

To Bridges' list of megachondrules, I added the info on the 12-mm BO
chondrule in my NWA 4679 (CK3.8) slice that I purchased from GIPO.

Best to all,

Bernd
