Project

Transition from magnetic to hydrothermal stage in complex pegmatites and its relatioship to the chemical composition of host rock (GA205/96/0855)

of pegmatite melt in a almost a closed system characterizes a primary (magmatic) crystallization of complex pegmatites. During a transition from magmatic to hydrothermal stage, a mixingof the residual pegmatite fluids and ...

Project

Evolved magmatic and pegmatitic systems as sources of critical raw materials and industrial minerals (TH79020002)

The PEGMAT project aims to: (i) identify most of the pegmatites and rare-metal the geological processes and structural constraints leading to pegmatite and RMG formation) characterize internal processes of pegmatite formati...

Element redistribution related to the alteration of rock-forming and accesory minerals in granitic rocks;examples from granitic pegmatites and episyen (GA205/07/1159)

Hydrothermal alteration of rock-forming and accessory minerals is widespread and locally intensive in various granitic and associated rocks (e.g. greisens, episyenites, pegmatites). It is initiated by late residual fluids closely related to ...

Tourmaline, dumortierite and their mineral assemblages as records of the melting process in B-rich peraluminous rocks from the Moldanubian zone (GA205/99/0434)

Tourmaline and less abundant dumortierite are typical minerals in magmatic and some high-grade metamorphic B-rich peraluminous rocks (leucocratic granites, migmatites, granitic pegmatites, granulites). They are commonly associated with AFM m...
