Abstract: Renziping seg is a subdepression of Cenozoic Qinxian Basin in Guangxi Province. Oil shale exploration area situates on the southwest margin of the basin. The oil shale associating with lignite formed in Yongning Series of Neozoic. The oil shale developed in lacustrineswamp environment under subtropical-tropical paleoclimate. Controlled by the tectonic activity, the development center of the oil shale is the deposit center in the seg. The oil shale stratum doesn’t suffer great damages during the later fault movements. Most of oil shale has the shape like lenticular and sill. In Renziping seg, the oil shale may have the potential for industrial use because of its high oil yield and shallow buried depth.

Key words: Renziping sag, oil shale, formation conditions, exploration prospect
