Abstract The organic matters that are closely correlative to uranium deposits are humic acids, fulvic acids, microorganism and bacteria. There is a strong correlation of sorption, complexation and reduction between humic acids and uranyl cation.The microorganism and bacteria play a subtle role in the uranium deposit formation.The study ways include experiment, calculation,rack-eval,X-ray analysis,fission-track,microprobe,infrared spectrum,fluorescence spectrum,ESR,NMR,gas chromatography,pyrolysis GC-MS ets.
