中文摘要：

近年来,在中国的二连盆地和鄂尔多斯盆地先后发现了湖相暗色泥岩中出现铀元素的异常富集且达到工业品位。为了进一步研究和开发湖相泥岩型铀矿,通过对国外黑色页岩型铀矿和湖相泥岩型铀矿研究成果的总结与分析,并结合目前对中国二连盆地努和廷铀矿、鄂尔多斯盆地南部延长组烃源岩铀富集已进行的初步勘查工作,认为湖相泥岩型铀矿成矿的有利条件包括：1充足且持久的铀源;2高含量的吸附剂与还原剂,吸附剂主要包括有机质和磷酸盐,还原剂主要为有机质和以黄铁矿为代表的硫化物;3低沉积速率和持续时间较长的缺氧环境;4氧化还原环境的突变,氧化还原边界的位置会直接影响铀成矿的位置;5有利的古地理条件,包括相对稳定的持续隆起的正地形和干旱、半干旱与潮湿周期性交替的气候。

英文摘要：

In recent years, the uranium enrichment in the lacustrine dark mudstone of production grade, has been discovered in the Ordos Basin and Erlian Basin of China. The present paper describes the study of this lacustrine mudstone-type uranium deposit further by summarizing and analyzing the researches of black shale-type uranium deposits and the lacustrine mudstone-type uranium deposits in foreign countries combined with preliminary exploration on the Nuheting uranium deposits in the Erlian Basin and the urani- um enrichment in southern Ordos Basin. The advantageous minerogenic conditions of the lacustrine mud- stone-type uranium deposit are： ①The existence of sufficient and sustainable uranium source.②High lev- els of adsorbents and reducing agents, with the adsorbents mainly including organic matter and phosphate, and the reducing agents mainly of organic matter and some sulfide represented by pyrite. ③Low deposition rate and the longer anoxic sedimentary environment.④The mutation of the redox environment, the redox boundaries directly affecting the position of uranium mineralization. ⑤Advantageous paleogeographic con ditions, including relatively stable positive landform uplifting continuously and periodic alternating cli- mate.
