Experimental constraints on the sources of lithium-rich granites and pegmatites

Communications Earth & Environment
Rare-metal granites and pegmatites are enriched in critical metals, such as lithium (>5000 ppm), relative to conventional granites in the crust (5000 ppm lithium) are sourced from the anatexis of enriched crustal rocks (>300 ppm lithium), followed by the

METALLOGENY OF EOCENE SYNCOLLISIONAL GRANITES OF MOTAJICA AND PROSARA MOUNTAINS

Rudarsko-geološko-naftni Zbornik, 2004
The geological setting is dominated by Eocene (48.7 Ma) syncollisional granitoids in the form of a small pluton in the Motajica Mt. and in the form of numerous sills and dykes in the Prosara Mt.

Fluid inclusion study of pegmatites from Vepice and Vlastějovice [PDF]

, 2015
Fluid inclusions of pegmatites from two localities in the Moldanubina Zone were studied in order to constrain PT conditions of their crystallization and establish composition and properties of fluids associated with pegmatite formation.

Pegmatites of the Anderson Ridge quadrangle, Fremont County, Wyoming [PDF]

, 1963
“The oldest rocks in the area consist mainly of para- schists of low to medium rank and restricted higher rank sillimanite schist. The entire series has been at least double folded. The most apparent are tight north to north- east trending folds.
