Pegmatite - Amelia pegmatite district

Pegmatite (Amelia district pegmatites). Leucocratic, coarsely crystalline pegmatite, occurs in discordant lens-shaped dikes and pods. Major minerals are quartz, microcline, albite, muscovite, garnet, and minor biotite; locally contains numerous rare and unusual accessory minerals (Pegau, 1932; Dietrich, 1990). Biotite and muscovite from the pegmatites have yielded Rb-Sr ages ranging from about 261 to 289 Ma (Deuser and Herzog, 1962).
