摘　　要： 目的探索多种矿产耦合成矿的盆地构造动力学问题。方法综合剖析鄂尔多斯盆地构造与油、气、煤和砂岩型铀矿等多种矿产共存富集的时空配置关系。结果鄂尔多斯盆地多种矿产相互关联、共存富集于古生界和中生界的不同地质层位,促使它们耦合成矿的时代主要发生在晚侏罗—早白垩世的燕山中晚期,主体受控于中新生代多构造演化及其关键变革时期的构造转换过程。结论探索、研究鄂尔多斯盆地中新生代构造动力学演化及其叠加转换关系,有助于客观认识多种矿产共存富集可能受控的统一盆地动力学环境及其耦合成矿效应。 Aim To probe into the basin dynamic environment of the coupling coexistence ot multiple energy resources. Methods By analyzing the time-space combinatorial relationship between oil-gas-coal-uranium resources formation and tectonic-dynamic evolution in Ordos Basin. Results Oil, gas, coal, and sandstone-type uranium deposit are abundant in Ordos Basin. These multiple energy resources accumulated in different sequences of Paleozoic to Mesozoic strata, but related to or depended on each other for coexistence. The coupling coexistence of the multiple resources mainly occurred during the Late Jurassic to Early Cretaceous in agreement with the middle to late Yanshanian, and controlled by the multi-cyclic tectonic evolution and tectonic regime transition in critical period. Conclusion It is important to study the tectonic-dynamic evolution and the composite characteristics of Ordos Basin, which can offer an integrated approach for recognizing the coupling effects and basin dynamic environment of multiple energy resources coexistence and accumulation.
