Somebody asked the following question off-list. I will attempt to answer it:

Question:
I am just wondering how a totally Iron body can be converted to shale just
two Kilometers from the original find. No offense, but isn't shale pretty
much silicon?

Waiting to be set straight.

Answer:
It is converted to iron shale when it becomes weathered or terrestrialized
(oxidized). This is a well-known
occurrence as far as iron meteorites go. Canyon Diablo can be found as both
iron shale and in elemental iron form depending on the degree of weathering.

Kind Regards,

Adam
