Mineralising Fluid Ascent Direction in the Sulphide Assemblage of Mosaboni, Singhbhum, Bihar

Distribution pattern of fluid inclusion homogenisation temparatures and assay of copper ores hove been uscd to ascertain the mineralising fluid ascent direction. Thetrigonametric relationships to calculate the parameters of this direction have been derived which show that the bearing of ascent of ore fluids isN 53.°E-S 53°W having plunge 38° and rake 77°. There is high probability of encountering rich ores underneath 30th level in a direction opposite to fluid ascent at selected locations.
