Titanian andradites up to 15.14 wt.% TiO2in chromitite from Nagaland ophiolite, India have been investigated. They are euhedral, complexly zoned and occur typically either as veinlets or in granular aggregates within serpentine-rich veins traversing the chromitites. Major element analysis and elemental mapping across the grains demonstrates several titanium pulses during their growth. Trace element analysis indicates sharp positive europium anomaly and negative strontium anomaly.
