Vogesite from Carbonatite Complex of Tiruppattur, Tamil Nadu, India

Abstract

Vogesite occurs as a melanocratic dyke rock in close proximity to carbonatite outcrops of Sevvattur. Vogesite was formed as a late magmatic differentiate of a monzonitic magma under CO₂-rich wet subvolcanic conditions. Postmagmatic fluids enriched in acidic components permeated through the rock causing development of lamprophyric character.
