鄂尔多斯盆地油、气、煤、铀富集特征分析

Enrichment features of oil,gas,coal and uranium in Ordos Basin

对鄂尔多斯盆地油、气、煤、铀4种矿产的富集特征进行了分析,对它们的共存特征和共生关系进行了深入研究。结果表明,盆地历经的构造运动和沉积环境的变迁决定了多种矿产富集的时空特征,盆地中铀的富集与深部油、气、煤的存在有密切关系,且盆地中铀的富集对油、气、煤成藏、成矿具有一定的促进作用。

The enrichment features and the coexisting relations of four types of minerals including oil, gas, coal and uranium in Ordos Basin were analyzed. It is indicated that the tectonic movement and environment change decided the mineralizing characteristics. The uranium enrichment in Ordos Basin is the important factor for promoting oil, gas and coal mineralization in deep formation.
