浅析鄂尔多斯盆地铀富集分布特征及影响因素

Enriching pattern and influencing factor of uranium in Ordos basin

基于对前人研究成果的吸收,从收集到的丰富地质资料、测井资料和岩心化验分析资料出发,对盆地中油、气、煤的赋存特征进行综合分析,对盆地中浅部及深部铀的富集特征进行比较分析。从盆地历经的构造运动对沉积环境变迁的影响出发,探讨盆地内的断裂带体系对铀富集分布的影响,进而依据盆地内断裂带体系存在证据和分布特征,研究盆地中油、气、煤对铀富集分布的促进作用,探讨4种矿产之间的关系。

For the purpose of researching the enriching pattern and influencing factors of uranium in Ordos basin, the distribution features of oil, gas and coal are analyzed comprehensively, the enriching pattern of uranium in middle and superficial part of the basin is compared with that in deep part, based on the predecessor research, the rich geologic information, and log and core testing data. Then, the influence of faulted zone system on uranium enriching and distribution is investigated according to the effect of basin tectonization on the sedimentary environment. And then, the accelerating effect of oil, gas and coal on uranium enriching is studied in the light of the evidence and being feature of faulted zone in the basin. At last, the relations between the four minerals are researched.
