Syllabus
  • 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. Characteristic of the rare-element pegmatites. Their shape, attitude and size, internal structure, mineralogy, geochemistry, models of internal pegmatite consolidation, origin of metasomatic assemblages, fractionation of elements. Relation of pegmatites to parental granites a their space distribution - regional zonality, pegmatite fields, belts and provinces. Theory of hydrothermal process in confrontation with recent hydrothermal activity (volcanoes, hydrotherms on the oceanic floor): a) T - P bounds of hydrothermal process b) chemistry of hydrothermal medium c) forms of material transportation in hydrothermal medium d) gas-fluid inclusions as indicators of hydrothermal medium Hydrothermal paragenesis - overview of mineralization types (Pb-Zn, Cu ores-in copper bearing sandstones) High temperature mineral paragenesis (formerly designated as pneumatolytic) Magmatogenic paragenesis (intramagmatic - platinoids, Cu-Ni-Fe, Fe-Ti, Ni-Co) Origin of minerals from volcanic exhalations. Disintegration processes (including sulphide deposits). Chemogenic sedimentation (evaporites, Fe-ores). Biomineralization. Origin of minerals during diaganesis. Contact metamorphism - mineral associations. Regional metamorphism - mineral associations. Metasomatic alteration and mineralization.
