Granitic Pegmatites, August 2012, Vol. 8, No. 4
$20.00
Nothing that geoscientists learn as students prepares them for interpreting rock textures as complex as those found in pegmatites. Understanding the textures and mineral zonation of granitic pegmatites is tantamount to understanding the fundamental process of crystallization.
Granitic Pegmatites
August 2012, Vol. 8, No. 4
Nothing that geoscientists learn as students prepares them for interpreting rock textures as complex as those found in pegmatites. Understanding the textures and mineral zonation of granitic pegmatites is tantamount to understanding the fundamental process of crystallization. It is a challenge to our ability to discern, beyond reasonable doubt, what is igneous and what is hydrothermal. This is the context that has drawn many professional geoscientists to the study of pegmatites for all or part of their careers. In addition, granitic pegmatites are important to our society as sources of raw materials for glasses and ceramics, silicon for microprocessors, and specialty metals including Li, Cs, Be, Nb, Ta, Sn, REE, and U. A very few pegmatites provide some of the most highly prized mineral specimens and colored gems found in national museums and personal collections around the world. No other rock type presents such a diversity of economic commodities in such concentrated fashion.
