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

Puntos clave

Lithium levels reached 2200 ppm in partial melts, indicating enriched sources for high-grade granites.
The study employed partial melting experiments on metasedimentary rocks containing up to 800 ppm lithium.
Experimental constraints suggest fractional crystallisation plays a role in lithium distribution in granitic systems.
The findings highlight the importance of sourcing from enriched crustal rocks during pegmatite formation.

Resumen

Abstract 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 moderate fractional crystallisation of the partial melts.
