pegmatite minerals chemistry

Pegmatite: An Intrusive Igneous Rock

Jun 13, 2018· The most common minerals in pegmatite are feldspar, mica, and quartz. While the mineral chemistry is highly variable, the elemental composition often resembles that of granite. However, pegmatite is enriched with trace elements, which make it even more interesting and commercially important. trace elements that makes pegmatite so interesting

Pegmatite Geochemistry

Hence, pegmatite is often characterised by sampling the individual minerals which comprise the pegmatite, and comparisons are made according to mineral chemistry. Geochemically, pegmatites typically have major element compositions approximating "granite", however, when found in association with granitic plutons it is likely that a pegmatite
