R-mode factor analysis for finding geochemical association of radioactive and trace elements in the QPC of Dhanjori basin, Singhbhum, Bihar

Factor analysis of multi-element data for Dhanjori conglomerates of Singhbhum district, Bihar, in eastern India reveals three factors accounting for about 57% of the total information contained in the data. Factors 1 and 2 are associated with radioactive elements. They also indicate that the provenance is a mixed felsic and mafic terrain, and that the minor and accessory constituents of these rocks are concentrated in the conglomerates. These two factors appear to result from the same sedimentological process. The factor-3 results from the V-Al diadochy. Factor-1 which is seen to be associated with both zircon and radioelements does not contain Pb. Pb is relegated to the factor-2. (author)
