古地磁研究结果表明，鄂尔多斯盆地寒武纪－早中奥陶世位于北纬１４°～２０°的古纬度区内，气候温暖潮湿，其南部和北部边缘的滨浅海相地层中可能富含生物有机质，是寻找该时期油气资源的有利地区；晚奥陶世－早石炭世，它可能经历了大规模的南北向水平构造迁移；晚石炭世－二叠纪，盆地处于北纬２０°左右地区，广泛发育的湖沼相沉积地层是煤成油、气的主要源岩层；三叠纪－侏罗纪，它位于北纬２４°～３１°，干湿交替的气候环境和差异构造旋转作用，为盆地边缘的油气形成和聚集创造了良好条件，因此有希望找到更多的中生代油气资源。
Paleomagnetism results show that the Cambrian-Early Middle Ordovician in the Ordos Basin is located in the latitudinal latitudes of 14 ° ~ 20 ° N latitude with a warm and humid climate. The coastal shallow marine facies at the southern and northern margins may be rich in bio-organic matter , Which is a favorable area to search for oil and gas resources of this period. It may have undergone a large-scale north-south horizontal structural transition from Late Ordovician to Early Carboniferous. In the Late Carboniferous-Permian, the basin was located at about 20 ° N, The developed lacustrine facies sedimentary formation is the main source rock of coal oil and gas. In the Triassic-Jurassic period, it is located between latitude 24 ° and 31 ° north latitude and alternates between wet and dry climatic environments and differential tectonic rotation, As oil and gas formation and accumulation have created good conditions, there is hope to find more Mesozoic hydrocarbon resources.
