Reconnaissance Geochemical Exploration for Copper in the Central Part of the Chitradurga Schist Belt, Karnataka, India

An area of about 115 Sq km was sampled on a 0.4 km spacing grid. The samples, collected from the bed rock, after removing the thin soil cover, were analysed for Cu, Zn, Pb and Co by the emission spectrograph using indium as internal standard. The Cu concentration map of the area shows nine zones of anomalous Cu content, the highest giving a value of 4000ppm. Of these, four zones of highly anomalous Cu content (2000 ppm-4000 ppm) are very promising and are recommended for detailed geochemical exploration.
