Abstract

Jayachamarajapura schist belt consists predominantly of ultramafic rocks (mainly komatiite) with minor metasediments of the Sargur group in the Western Dharwar Craton. Sampling of plant species and soil over high magnesia komatiite-bearing areas of this belt has been carried out. Out of the seven plant species analysed, one species, i.e. Vicoa indica has indicated higher Ni values (540-896 ppm), and its potential as a local indicator for Ni has been recognized. The soil samples have yielded distinct signatures of Ni (3126- 12,406 ppm) and Co (382-1071 ppm). The high Mg content of the soil samples indicates that the soil profile is mostly derived from undifferentiated komatiitic bed rocks, and the observed anomalies of Ni and Co warrant a detailed study of this belt for possible Ni-Co mineralization.
