摘要: 抚顺盆地位于郯庐断裂带北延东支[CD2]抚顺[CD1]密山断裂带上,盆内赋存有厚达200 m的巨厚油页岩层,按含油率高低,可分为上部富矿层和下部贫矿层。富矿层中水平层理发育,含油率多为5%~8%,最高可达12%;贫矿层中层理很少,多数层段含油率小于3%。地球化学分析结果显示,油页岩中有机碳含量较高,最高可达13.1%。油页岩属Ⅰ[CD*2]Ⅱ型干酪根,成熟度较低。整个含油页岩岩系的形成经历了盆地初始裂陷、加速裂陷、稳定发育、较快速裂陷、较慢速裂陷、终止裂陷6个阶段。综合分析表明,油页岩贫矿层形成于盆地周缘夷平程度较高、物源供给较少、盆地基底沉降相对较快、有机质堆积比例较低的浅湖环境;油页岩富矿层形成于盆地周缘夷平程度较高、物源供给较少、盆地基底沉降速率相对缓慢、有机质堆积比例相对较高的浅湖环境。

Abstract: The Fushun Basin is located in the FushunMishan fracture zone, the later being the eastern branch of the northern extension of the famous Tanlu Fault. The oil shale is up to 200 meter thick and can be divided into the upper richer and the lower lean oil shale layer based on their oil yield. Horizontal beddings were developed in highgrade oil shale whose oil yield usually are between 5%~8% and up to 12%. There are little beddings in the lowgrade oil shale layers with oil yield of less than 3%. Geochemical analysis indicates that the organic carbon content is higher in the oil shale, with a maximum up to 13.1%. The oil shale contains Ⅰ-Ⅱtypes of kerogen with low maturity. The oil shalebearing succession in the basin underwent six stages of evolution: initial rifting, accelerated rifting, stably rifting, moderately rifting, slowly rifting and terminating rifting. Synthetic analysis indicates that both the lean and rich oil shale were formed in a shallow lake environment when the surrounding margins of the basin underwent higher leveling and when limited material was provided into the basin. However, the former was formed when the base of the basin subsided relatively quickly and when the organic material accumulation rate was not too high. The latter was formed when the base of the basin subsided slowly and when the organic material accumulation rate was very high.

Key words: Fushun Basin, oil shale, geological characteristic, ore-forming process
