Bernd and all,

I have a large collection of impactites from all over the world, yes they
were caused by meteoritic impact but few have material identifiable from the
impactor. My Monturaqui contains visible metallic grains but I had never
thought to check my other impactites. Thus far I have only found one other
and that is a slice of Ternovka, a black material that is quite magnetic. I
would be interested to have others check their collections for this feature.

Dan
