Abstract: The uranium mineralization is distributed in sedimentary metamorphic rocks,granite and volcanic rocks in the central and western Jiangxi.According to the analysis,the argillaceous,carbonaceous,siliceous slate,carbonaceous phyllite,metasandstone and mica schist of the NanhuaCambrian system are regional uraniumrich strata and uraniumbearing rocks in the central and western Jiangxi.The chemical compositions of the five uraniumproducing granites conform to the general rules of chemical compositions of uraniumproducing granites.The mineralization of volcanic rocks is related to the higher basic number of tuff and the higher uranium content of accessory minerals,which do not have the value of uranium mineralization prospect.Uranium mineralization of any lithology is in a certain favorable geological environment,and the basement strata are mostly regional orebearing properties.Uranium mineralization in various rocks is related to longterm active regional faults.
