Origin of granitic pegmatites and their minerals - role of fluida in their orign. The four classes of granitic pegmatites (abyssal, muscovite, rare-element, miarolitic), their origin. Classification of pegmatites of the rare-element class and pegmatite types: rare-earth with allanite-monazite and gadolinite subtypes* beryl with beryl-columbite, beryl-columbite-phosphate subtypes, complex with spodumene, petalite, lepidolite, elbaite, amblygonite subtypes* albite-spodumene, albite.
