It’s not Fe, Ag, or Au, but for growth of cuprite whiskers (chalcotrichite), you can see this:

Two related questions: Is anyone aware of papers describing native iron in a wire habit, akin to
what is sometimes present in native silver and native gold? I have a lot of papers on native iron
and nearly all seem to illustrate or describe a generally granular or blocky or irregular habit.

Second, why does a ‘wire’ habit develop in these isometric minerals? Any papers describing this
would be much appreciated.
