Manganocolumbite in the pegmatites of Bhurpidungri(Lat: 21°51'30": Long: 84°15'52", T.S.No.73C/5) in the Jharsuguda district of Orissa is reported for the first time from the pegmatites of India. It contains upto 18.46% MnO, with an average (n=8) of 14.52% MnO, 7.26% FeO(T), 60.18% Nb2O5 and 14.33% Ta2O5. A swarm of pegmatites is exposed, intruding at the contact of granite gneiss and amphibolite/Charnockite near the Bhurpidungri village. These pegmatites are well-Zoned with prominent quartz core, intermediate zone and wall zone. About 4 tonnes of manganocolumbite has been estimated in the gravels of these pegmatites for exploitation. Apart from this, beryl is also found in sufficient quantity.Keywords
