Truly a weird meteorite! While some of the preliminary data support Michael
Farmer's first guess - that it is an H chondrite - probably an H5 chondrite* -
other data might speak in favor of an L or LL type. Hey, maybe this is an
exotic H/L(LL) type like Bremerv=F6rde, Haxtun, Tieschitz or Matt Morgan's
new H/L3-4 !!!


* See Mike's website: "The meteorite appears to be a very fragile chondrite,
I saw many small chondrules, and some metal. My guess is (H5)."


Best wishes,

Bernd
