Compositional Characterisation of Biotite from the Gamkak and Jaiyor Areas in the West Siang District, Arunacha! Pradesh with Implications on Uranium Mineralisation

摘要

Compositional characterisation of biotite from two distinctly different geological domains of the Gamkak and Jaiyor areas in the West Siang district, Arunachal Pradesh has been carried out. The environments of formation of biotite in the areas have been inferred from the compositional data. Conspicuous differences in chemistry have been observed in biotite from mctamoiphic mica schist and hydrothcrmal uraniferous vein.
