Mining a Pegmatite | Actforlibraries.org

Mining a Pegmatite. Earth Science. Pegmatites come in two flavors simple and complex, or dirty. The complex pegmatites are the source of many rare minerals used both as gemstones, and rare metal ores. Pegmatites being relatively small in comparison to other mineral deposits lend themselves to small mining operations.
