EVOLUTION OF CHEMICAL COMPOSITION AND CRYSTAL MORPHOLOGY OF AEGIRIN DURING FORMATION OF THE VISHNEVOGORSK ALKALINE CARBONATITE COMPLEX (SOUTH URALS)

The chemical composition and crystal morphology of aegirine changed during formation of the Vishnevogorsk alkaline carbonatite complex. Fenitization of host metamorphic rocks, early vein syenites and pegmatites resulted in crystallization of pyroxenes with minimal content of aegirine end-member (up...
