Here we report anomalous uranium concentration in tourmaline-bearing leucogranite occurring at Nuranang, Tawang district, Arunachal Pradesh, North East India. The leucogranite occurs as concordant layers parallel to gneissic foliation, similar to the gneisses of the Palaeopro-terozoic Se La Group. It is medium to coarse-grained, and is composed of quartz, potash feldspar and plagio-clase as dominant minerals with variable proportions of muscovite, biotite, tourmaline and garnet. Apatite, zircon and pyrite are accessory minerals. Geochemically, the leucogranite is alkali-rich, peraluminous and highly differentiated. It is emplaced in a syn to late orogenic collision tectonic setting. Analyses of 10 granite samples collected at 500 m intervals show relatively high radio -elemental concentration (U: 5-96 ppm, Th: 5-23 ppm, K: 2.23-7.72% and Th/U; 0.07-1.00, n = 10) compared to normal granite. Anomalous uranium concentration in the leucogranite is observed in a 200 m x 50 m area at Nuranang. Samples from this area have assayed 0.016- 0.029% U3O8 and <0.005% ThO2. Leachable U3O8 con-tent determined in five samples varies from 81.25% to 87.50%. Preliminary studies indicate that uranium is in the adsorbed state associated with iron oxide and alte-red feldspar/clay. The findings of anomalous uranium concentration in tourmaline-bearing leucogranite likely open up a new target area for uranium search in the Higher Himalaya of Arunachal Pradesh.
