conc_proc:	Dodson And Others, 1974 , Believe That The Following Sequence Of Events Have Been Responsible For The Formation Of The Uranium Deposits Of The Rum Jungle-Alligator Rivers Province: (1) Syngenetic Enrichment Of Uranium In Carbonaceous (Algal?) Sediments During The Lower Proterozoic; (2) Concentration Of Ore-Grade Deposits Of Uranium Minerals In Favourable Places From Mineralized Solutions Mobilized During A Major Igneous/Tectonic Event; And (3) Relocation Of Uranium By Circulating Solutions Through Leaching And Redeposition Not Far Away.
