Study of the nickel silicates associated with the ultrabasic rocks of Nuggihalli schist belt, mysore state

  • Published:
Proceedings / Indian Academy of Sciences

Abstract

The occurrence of some nickel silicate minerals as encrustations along joint planes and shear zones of the chromite bearing ultrabasic rocks of Nuggihalli schist belt is described. Chemical and X-ray study shows besides amorphous nickel silicate, the presence of granierite, nepouite or nickel antigorite. The nickel minerals are secondary developed by the action of circulating waters. The source of nickel is olivine, in the structure of which Ni is known to be present, either as camouflaged or captured ion.
