Ordos basin is prolific in oil

gas

coal and uranium resources. Vertically

oil

coal and uranium distribute mainly in Jurassic

while gas distributes mainly in Permian and Ordovician; natural gas is located below oil and uranium

and closely above and/or below the Permo-Carboniferous coal measures. Laterally

oil distributes in the central and southern ports of the basin

uranium deposits are located in the northern and western edges of the basin

natural gas and coal distribute in the whole basin

and recoverable coals distribute in the basin margin. Gas distributions in Lower and Upper Paleozoic have been controlled by the palaeokarsts formed in the late Caledonian to Hercynian fossil weathered crusts

and the widely distributed large braided river delta front sediments

respectively. The accumulation of coal has been controlled by the turning stage of tectonism and palaeoclimate

and the enrichment of uranium has been controlled by oxidation-reduction environment. The minerogenic evolutions of various energy resources in the basin are characterized by their obvious phasic development

and the commercial energy resources have been accumulated in a sequence of coal→uranium→gas→oil. Yishan slope area is favorable for exploration of oil

gas

coal and unconventional gas; Tianhuan depression and the thrust belts on the western edge of the basin are favorable for joint exploration of oil

gas

coal and uranium;Yimeng uplift and Weibei and Jinxi flexural fold belts are favorable for joint exploration of coal

coalbed methane and uranium.
