Trace elements in quartz from Li-enriched pegmatite

Quartz from complex LCT pegmatites has similar evolutionary trend as quartz from fractionated granites: systematic increase of Al, Li, and Ge. In comparison with the most fractionated peraluminous granites, pegmatitic quartz is relatively depleted in Li, but strongly enriched in Ge. Minerals associated with crystallizing quartz may strongly influence the distribution of trace elements between quartz and melt. This influence is stronger in the pegmatitic than granitic melt.
