SummaryGranitic pegmatites characterized by advanced accumulation and fractionation of incompatible rare lithophile elements (Li, Rb, Cs, Be, Ta ≶ Nb, B, P and F), often contain mineral assemblages which host lithium-rich micas. Lepidolite and lithian muscovite occur in high-pressure spodumene, low-pressure petalite, phosphorus-enriched amblygonite and fluorine-rich lepidolite subtypes of orogenic affiliated complex type granitic pegmatites and rarely in anorogenic affiliated amazonite… Expand
GEOCHEMISTRY, MINERALOGY, AND EVOLUTION OF Li-Al MICAS AND FELDSPARS FROM THE MOUNT MICA PEGMATITE, MAINE, USA
Mount Mica is a poorly zoned, sodic LCT-type pegmatite consisting dominantly of quartz, albite, and muscovite in the outer portion of the pegmatite. Micas are the principal K minerals throughout theExpand
Trace element geochemistry by laser ablation ICP-MS of micas associated with Ta mineralization in the Tanco pegmatite, Manitoba, Canada
In the Tanco pegmatite, one of the world’s major Ta deposits, tantalum mineralization shows a complexity that reflects the complex petrogenesis of its host pegmatite. Micas are common in most of theExpand
Geochronology and geochemistry of rare-element pegmatites from the Superior Province of Canada
The crystallisation age and thermochronology of late- to post-orogenic, rare-lithophile element (Li, Cs, Ta) pegmatites that are chemically associated with peraluminous granites have been determinedExpand
The magmatic–hydrothermal transition in rare-element pegmatites from southeast Ireland: LA-ICP-MS chemical mapping of muscovite and columbite–tantalite
Abstract The processes involved in the magmatic–hydrothermal transition in rare-element pegmatite crystallization are obscure, and the role of hydrothermal mechanisms in producing economicExpand
