Purpose: The purpose of The Pegmatite Page is to provide a forum for those of us interested in pegmatites (pigs!). Information on recent finds, journal articles relating to pegmatites and information about upcoming shows and conferences.
What is a Pegmatite? A pegmatite is
simply a very coarse grained igneous rock that usually occurs in
dikes (seams of rock that cut across the main country rock) or
lenses (pods of coarse-grained igneous rock included in other
rocks). Pegmatites can be from a few inches to hundreds of
feet thick. What makes many people interested in
pegmatites is the fact that many exotic and important minerals,
including many gemstones, are found in them.
