Similar conglomerate have been delineated within Neoarchean-Paleoproterozoic Gorumahisani-Badampahar schist belt Dhanjori volcano-sedimentary basin lying along northeastern fringe Singhbhum-Orissa craton in eastern occurrences reported previously craton; however, no detailed report on genesis is available. work focuses nature mineralization hosted radioactive Iron Ore Group craton. The predominantly matrix supported oligo-mictic nature. Petrography, microprobe data, scanning electron microscopy studies reveal presence chromite, zircon, rutile, magnetite, monazite, pyrite, chalcopyrite, pyrrhotite, stibnite, brannerite. Laser ablation-inductively coupled plasma-mass spectrometry analyses various generations arsenian pyrites significant concentrations Au solid solution. was initially incorporated its detrital form onto growing pyrite surfaces, possibly due microbial mediation. trace element data with back-scattered images X-ray compositional maps remobilization associated elements diagenetic precipitation younger hydrothermal pyrites. sulfide-hosted mineralization, signatures, zoning patterns mimic style sediment-hosted deposits such as Spanish Mountain Carlin. However, broad terms, origin these resembles modified placer model deposition Witwatersrand conglomerates. first refractory has important implications exploration region analogous areas.
