| Abstract: | Based on the study of regional tectonics,stratum, lithological character, factes paleoleography, uranium mineralization character and its controlling factors, this paper discusses the mineralization mechanism and model of interlayer oxrdation zone sandstone type uranium deposit in Yili basin. The factes model of mineral- bearing host shut xigou group alluvial apron which empties fastly into lake is set up after synthetically analysing rarieties of sedimentary environment marker and dividing sedimentary rhythm,and the sub-factes is also diided. The main ore layer belongs to delta sub-factes. The corresponding figures are drawn. Some proposals are suggested for dividing minerogenetic prospect province and future work. The south-west basin, especially the area between 512 and 511,is the key area for probe in future. |
