Abstract
A quantitative determination of Ni from a large number of basaltic rocks of India of different geological ages has been made. The present study gives an average of 66 ppm Ni for 55 analyses of Indian basalts. The olivine tholeiites and alkali olivine basalts contain, in general, more Ni than the quartz tholeiites. The upper Deccan basalts are entriched in Ni compared to the Lower Deccan basalts. It is observed that the amount of Ni is controlled by both Mg and Fe+2 contents of basalts. However, in the present study an apparent correlation of Ni with Fe+2 is noteworthy.
