"I have found on a 151g Erg Chech/Mali Meteorite a metallic inclusion, looking
uncommon in my opinion. I would ask for some comments and thoughts about what
this might be and if other people have already seen such an inclusion. The
inclusion is attracted by a magnet. Hope the pictures show that the part of
the inclusion, outside of the Meteorite, has a crystal form with well defined
edges."

Hi Andi and List,

Wow, a very intriguing feature of this Erg Chech individual. Well, it looks like a
duck (i.e. cubic crystal habit), it quacks like a duck (i.e. magnetic), so my guess
is it may be a magnetite crystal protruding from the matrix.

Its cubic crystal habit reveals that it belongs either to the spinel series,
the magnetite series or to the chromite series.

Erg Chechically,

Bernd
