Top one is pyrophyllite - one of the more common minerals at Graves Mountain. The iridiscent mineral is goethite - its a variety known locally as turgite.

I like the iridiscent mineral, and never heard of it, as I would have identified it as: peacock ore or bornite.

Renata, these iridescent goethites are well-known from Graves Mountain, Georgia. It looks like others from that locality so I would safely make the assumption thats what it is, considering the user specified its from that locality.
