Description

This is a view of the mine dump of the Dan Patch Pegmatite Mine, just west of Keystone, South Dakota. The light colored pegmatite rock is composed primarily of large crystals of quartz, albite feldspar, and muscovite, with lesser amounts of tourmaline and beryl. The pegmatite is an igneous rock that was intrusive into metamorphic schists (visible at the right side of the image). Both of these units are part of the uplifted Precambrian core of the Black Hills.

    This was only of my favorite mines I visited while going to SDSM&T back in the early 80s.
