东北地区敦密断裂带分布着多个煤系油页岩盆地，但沉积岩之间的沉积组合和产状特征存在一定差异。根据前人地层对比研究结果，抚顺盆地沉积物的沉积时代为古近纪—始新世，桦甸盆地为始新世渐新世，梅河盆地为始新世—早渐新世。抚顺盆地古城子组发育巨厚厚煤层，纪军屯组下部分布厚层低质油页岩，纪军屯组上部发育厚层优质油页岩。梅河盆地梅河组下煤段和上煤段均沉积煤层，中泥岩段发育油页岩层。桦甸盆地油页岩段沉积薄层优质油页岩，碳质页岩段发育薄层煤层。敦密断裂带构造沉降初期，古气候温暖湿润，厚煤层主要沉积在陆生植物供给丰富的沼泽地。这三个盆地的深湖均在最大构造沉降演化阶段形成了较优质的油页岩层，有机质来源于藻类。抚顺盆地和梅河盆地的油页岩沉积于温暖湿润的古气候中，而桦甸盆地的气候则由湿润到干燥变化。考察表明，敦化—密山断裂带经历了2个成煤阶段和1个油页岩形成阶段。抚顺盆地和梅河盆地下部煤层堆积于伊普勒期，桦甸盆地和梅河盆地煤层堆积于伊普勒期。 * 通讯作者：e-mail sunpingchang711@126.com 孙平昌等。梅河盆地上部204沉积于巴托阶-普里亚博阶。相比之下，这三个盆地的油页岩层均在鲁特阶阶段矿化。
Several coaland oil shale-bearing basins are distributed in the Dunhua-Mishan Fault Zone in Northeast China, while there are certain differences in sedimentary association and occurrence characteristics between the deposited rocks. Based on the results of previous research on stratigraphic correlation, the depositional age of sediments in the Fushun Basin is the Paleogene-Eocene, in the Huadian Basin it is the EoceneOligocene, and in the Meihe Basin, the Eocene-Early Oligocene. In the Fushun Basin, huge thick coal seams were formed in the Guchengzi Formation, thick low-quality oil shale layers were distributed in the lower part of the Jijuntun Formation and thick high-quality oil shale layers were developed in the Upper Jijuntun Formation. In the Meihe Formation of the Meihe Basin, coal seams were deposited in both the Lower Coal-bearing Member and the Upper Coal-bearing Member, while oil shale layers were formed in the Middle Mudstone Member. In the Huadian Basin, thin highquality oil shale layers were deposited in the Oil Shale Member and thin coal seams were accumulated in the Carbonaceous Shale Member. Thick coal seams were mainly deposited in the swamp with abundant land plant supply during the initial tectonic subsidence stage of the Dunhua-Mishan Fault Zone in the warm and humid paleoclimate. Relatively high-quality oil shale layers were all formed in the deep lake during the maximum tectonic subsidence evolution stages of these three basins, and the organic matter sourced from algae. Oil shale in the Fushun and Meihe basins was deposited in the warm and humid paloeoclimate, while in the Huadian Basin the climate varied from wet to dry. Investigation showed the Dunhua-Mishan Fault Zone to have gone through two coal-forming stages and one oil shale-forming stage. Coal seams in the Fushun Basin and the lower part of the Meihe Basin accumulated in the Ypresian stage, while those in the Huadian Basin and the * Corresponding author: e-mail sunpingchang711@126.com Pingchang Sun et al. 204 upper part of the Meihe Basin were deposited in the Bartonian-Priabonian stage. In contrast, oil shale layers in these three basins were all mineralized in the Lutetian stage.
