In the North Ordos basin the sandstone-type uranium deposits developing in the system of sandstone beds of sedimentary facies of braided river course in Midde Jurassic Series,at the same time it happen some show of ore:the alteration zone of chloritization,bleaching decoloration and carbouation of epigenetic alteration,which show of ore are immediate and indirect for uranium mineralizing process.

摘 要：发育于内蒙古鄂尔多斯盆地北部中侏罗统直罗组辫状河相杂砂岩体内的砂岩型铀矿，有一系列较为特殊的与放射性铀成矿有直接或间接关系的成矿地质现象：绿色化蚀变带、漂白退色化带、二次胶结钙化砂岩团块及钙化砂岩断续层与&钙化木&后生蚀变现象；在与铀矿化和与油气的关系认识上存在一定分歧。

The split between the two groups can hardly be papered over.
