摘要
敦密断裂带中抚顺盆地、梅河盆地和桦甸盆地等富含煤、油页岩等能源矿产,这些能源矿产在3个盆地中展布存在一定规律,在抚顺盆地中含煤沉积主要位于盆地底部,油页岩位于盆地中部,梅河盆地上下分布两层含煤沉积,中部发育油页岩沉积,而桦甸盆地油页岩位于盆地中部,而含煤层系位于盆地上部。以油页岩层系为3个盆地的等时层位,根据岩石组合特征和能源矿产分布位置,表明敦密断裂带西南段(抚顺盆地)为持续稳定深水沉积,向东北方向,水体逐渐变浅,且在构造反转时期,东北段湖泊最先消失。
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.
