[meteorite-list] Norwegian meteorite classification guessing game

[Martin Horejsi]

My guess is still an CO.

Here is a pic of a small block of Ornans sticking extremely well to a
magnet. The magnet attracted the Ornans so well that I have to be
careful that the specimen is not chipped when it jumps to the magnet!

Happy viewing,

Martin
