Kaersutite megacrysts in the alkaline mafic dikes of the Panticosa pluton (Pyrenean Axial Zone, Spain): deep-origin xenocrysts

Megacrysts of kaersutite have been identified in several alkaline mafic dikes from the Panticosa pluton. They show strongly anhedral habits and resorption features, including Krs overgrowths and/or Cpx-Opq coronae. Chemically, the liquid in equilibrium with the megacryst cores is clearly different f...
