The tenor of uranium ore in the mineralised field of Jaduguda has been statistically analysed. Distribution, the variations of the tenor in different directions and the continuity of mineralisation in the different directions (using the geo-statistical parameter, variogram) have been studied and it has been found that the distribution of the metal in Jaduguda is log-normal and the variations of tenor in the different directions are unique parameters in the mineralised tract. The variograms for tenor in Jaduguda are found to be of the 'transitive' type. The frequency histogram of the tenor of the ore across the strike, brings out the possibility of the mix-up of two populations, in the central portion of the deposit, probably by post mineralisation structural deformations like strike-slip faults.

Abstract


The tenor of uranium ore in the mineralised field of Jaduguda has been statistically analysed. Distribution, the variations of the tenor in different directions and the continuity of mineralisation in the different directions (using the geo-statistical parameter, variogram) have been studied and it has been found that the distribution of the metal in Jaduguda is log-normal and the variations of tenor in the different directions are unique parameters in the mineralised tract. The variograms for tenor in Jaduguda are found to be of the 'transitive' type. The frequency histogram of the tenor of the ore across the strike, brings out the possibility of the mix-up of two populations, in the central portion of the deposit, probably by post mineralisation structural deformations like strike-slip faults.
