Hi All,

Recently I have read a few posts to this list that definitively claim that
irons do not form a fusion crust. Yet, in Norton's "Rocks From Space",
[pg 167 in my softbound edition] it clearly states the following;

"Iron meteorites have the thinnest crust of all, usually only a small
fraction of a millimeter thick. A fresh crust is blue-black to black and
looks like freshly welded steel. This crust is fragile and easily
destroyed if the meteorite weathers for even a short time."

So, which is true? Crust or no crust for irons?
