Abstract

Gold is one of the most important economic minerals of our country and therefore, prospecting of gold is carried out in various parts of our country. The major prospecting of gold is carried out in Neo-Archean Dharwar Craton area. The investigated area of gold prospect is located Ajjanahalli, Sira town of Tumakuru District of Karnataka, India. It is a part of 57C/9 toposheet prepared by Geological Survey of India (G.S.I.) and lies within the rectangular grid bounded by latitudes 13°42’55”to 76°43’15”E and is designated as Block-F by GSI for convenience. Detailed mapping on scale 1:2000 is done using handhold GPS over an area of 1200 sq m. Drilling of four borehole was done with total depth of 558.2 m. The area comprises of meta-basalt, BIF (banded iron formation), meta greywacke, meta-argillite with minor ferro-dolomitic bands with basic dykes and quartz, carbonate veins of Chitradurga Group of Dharwar Super group. Moderately plunging tight isoclinals folds pre-dominate the terrain. The mineralisation is basically within the sheared sulphide and carbonate facies. BIF shows developing of quartz-carbonate veins that show lesser but fair amount of mineralisation zone occurring along the parallel shears within the BIF.
