Pegmatite deposits in the Republic of South Africa ...

The Peerless pegmatite, half a mile south of Keystone, Pennington County, S. Dak., has been a major source of scrap mica and beryl. Feldspar, amblygonite-montebrasite, tantalite-columbite, and cassiterite also have been recovered. The pegmatite intrudes Precambrian quartzmica schist.
