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。初步分析了它们的形成、成因及与铀成矿的关系及其找矿意义。

关 键 词:特殊呈矿现象  成矿作用  东胜砂岩型铀矿  内蒙古

Abstract: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 happens 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. In this area are understanding differences uranium mineralizating relation between to those alteration . This paper preliminary analyse these show of ore, the formation, the genesis, relationship between the uranium mineralization and prospecting signifeance.
Keywords:show of ore  uranium mineralizing process  sandstone-type uranium deposis  Dongsheng  Inner Mongolia
