Abstract The Qianjiadian sandstone-type uranium deposit in Songliao Basin has become an ultra-large uranium deposit since its exploration and continuous development. The geological and metallogenic characteristics of this area have been studied widely since its discovery,but the detailed petrological features of its ore-bearing construction and favorable metallogenic conditions still require much detailed research. The mineralization of urnium deposit includes various geological processes resulting in the accumulation of uranium element. The source rock with high uranium concentration and much easier for the leaching of uranium is the basis of uranium mineralization. The later oxidation-reduction,mineral alteration are the key for the uranium deposits. In this paper,the petrological characteristic of lithology sandstone-type uranium deposit is studied by using the micro experimental analysis. It is found that the host rocks are primarily composed of medium-fine grained feldspar lithic sandstone,fine grained feldspar lithic sandstone,boulder-clay-bearing sandstone and glutenin. The amount of quartz and feldspar are close to the rock debris. The debris are mainly composed of rhyolite,rhyolitic tuff,and some trochyte,ayenite-aplite,granite,granite porphyry,andesite,silicalite and mudstone etc. the epigenetic alteration includes the carbonatization and kaolinization is general and intense at the local region,followed by the secondary epigenetic alteration includes pyritization,ferrugination and little baratization. Deep oil and gas infiltrate into the oil-bearing strata causing the oil stains,spots and spillage. The symbiosis of pyrite berry globule and micritic pyrite are common. The uranium element exists in the uranium-bearing minerals(e.g.,asphalt and coffinite)as well as the adsorbed state. The multi-genesis and multi-stages of the metallogenic model is established,i.e.,sedimentary preconcentration stage-interlayer infiltration stage-the oil and gas transformation stage-the oil and gas reduction stage.
