INTERNATIONAL GEOLOGICAL CONGRESS 2012 AUSTRALIA

Dr. Jayshree Panjikar represented India at the International Geological Congress in Australia in 2012 and presented technical paper on 'Alexandrite of Indian Origin' along with Mr. Aatish Panjikar. Al;exandrites from three Indian states were discussed : Chhatisgarh, Odisha and Andhra Pradesh. UV-Vis-NIR, FTIR, Laser Raman Spectroscopy, LIBS and EDXRF were used and the characteristic microscopic inclusions were investigated to categorize the alexandrite. Although Alexandrite from the three different states of India, viz. Chhatisgarh, Odisha and Andhra Pradesh, are separated from each other by hundreds of kilometers, they are found in the similar geological rock type the Khondalite-garnet sillimanite gneiss and garnet biotite gneiss. Inclusion study and the similarity in some of the properties indicate that these different locality Alexandrite may have been emplaced at a similar time in the geological history. Fluid inclusion studies would throw light on the exact temperature pressure conditions. Based on the data collected and inclusions investigated it is predicted that  there is large possibility of finding many more alexandrite deposits in these regions as well as between the localities where presently alexandrite and chrysoberyl are being found.
