Sectoral Zoning in Natural Fluorites from Carbonatite Rocks of Ambadongar, Gujarat

In this article, we want to examine the presence of various types of zoning and spatial distribution of luminescence activating trace elements including REEs in natural fluorites from carbonatite rocks of Ambadongar, Gujarat. At Ambadongar, fluorite occurs as veins and vugs in different colours e.g. blue, yellow, green and purple associated with carbonatite and alkaline rocks. Cathodoluminescence microscopy was used to study the internal morphology including growth sectors, growth bands and concentric zoning patterns in fluorite crystals.
