conc_proc:	Syngenetic Deposition Before 1880 M.Y. And Remobilization (?) At 1700 M.Y. Followed By Periods Of Lead Loss At 900 M.Y. And 500 M.Y. - Ages Which Cannot Be Related To An Igneous Or Tectonic Event. 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.
ore_ctrl:	Sediments Dip Steeply Away From The Late Archean Rum Jungle Complex, Indicating Post-Archean Updoming Of The Complex At The Close Of Sedimentation In The Pine Creek Geosyncline. The Complex Is Cut By The Gian* Reel Fault. The Anomalies Align With Local Fault.
