抚顺盆地、梅河盆地和桦甸盆地位于敦化-密山断裂带，盆地内发育煤和油页岩。这些能源矿物存在分布规律。在抚顺盆地，煤和油页岩分别沉积在盆地地层的底部和中部。含煤地层发育在盆地的上部和下部，而油页岩则发育在梅河盆地的中部。而煤和油页岩则分布在桦甸盆地的上部和中部。根据岩石组合特征和能源矿物分布，将油页岩作为等时层结果表明，敦化-密山断裂带西南部(抚顺盆地)为持续稳定的深水沉积，越往北越浅，在构造反转阶段，东北部湖泊首先消失。
Fushun basin,Meihe basin and Huadian basin are located in the Dunhua-Mishan fault zone,and the coal and oil shale layers are developed in these basins.These energy minerals exist distribution regularities.In the Funshun basin,the coal and oil shale deposited in the bottom and middle part of the basin strata separately.The coal bearing strata developed in the upper and lower part,while the oil shale layers developed in the middle part of the Meihe basin.However coal and oil shale layers are happened in the upper part and middle part of the Huadian basin.Take the oil shale-bearing layers as isochronous beds,on the basis of the rock association features and energy minerals distribution,showed that it was sustained stable deep water deposition in the southwest part of the Dunhua-Mishan fault zone(Fushun basin),the more to the northeast,the shallower water,and in the tectonic inversion stage,the lake in the northeast part was disappeared firstly.
