Classification of Granitic Pegmatites and Pegmatite-Bearing Granitic Systems

Geology of Ore Deposits, 2018
The paper discusses the concepts of pegmatitic rocks, pegmatite and pegmatoid bodies, and classification of granitic pegmatites and their relationships with various types of granite. Six types of pegmatitebearing granitic systems (PGS) are proposed: (I–PGS) granitic series with normal alkalinity in the form of central-type plutons with crystal-bearing ...

The Pegmatite Puzzle

Elements, 2012
Virtually every conceivable model to explain the internal evolution of granitic pegmatites had been proposed by the 1920s. Two of these hypotheses have prevailed: (1) the fractional crystallization of flux-bearing granitic melt inward from the margins of the pegmatite body to the center, and (2) the buoyant separation of an aqueous fluid from the ...
