Abstract

A small and economically unimportant molybdenite mineralization is found in the Peninsular gneisses around Yegawakote. Pyrite and chalcopyrite are the other ore minerals found associated with molybdenite. These minerals are found as fracture fillings in quartz veins.

Fluid inclusion studies on quartz carrying ore minerals reveal the presence of carbonic, through CO₂-H₂O, to entirely pure aqueous saline fluids. Microthermometric data show that most of the aqueous inclusions are in the salinity range of 4 to 15 wt%. NaCl have formed at temperatures of around 200-370 °C.
