... with a chemical composition of a Li-bearing beusite enriched in Mg, derived possibly by contamination by the host rock after the crystallization of the border and wall zones of the pegmatite. The exsolution of this precursor led to the formation of a lamellar intergrowth of beusite and lithiophilite enriched...

... in the Cema pegmatite ( Roquet 2010 ). The first one is albite-rich, and could be related to an episode of Na metasomatism after the primary crystallization of the pegmatite, at a subsolidus stage. The second one, muscovite-rich, could have developed during a hydrothermal stage of greisen formation...
