| 摘 要： | 黄县盆地是我国东部重要的煤与油页岩资源赋存区。采用沉积学、层序地层学及构造地质学等多种学科研究方法,对黄县盆地煤与油页岩组合类型进行研究,并在层序地层格架下分析不同组合类型的沉积环境演化,这对于该区煤与油页岩资源勘查具有重要意义。研究结果表明:(1)该区煤与油页岩组合类型有四种型式:油页岩/其它沉积/煤层共生组合(煤4-泥岩-油4组合)、煤层/油页岩共生组合(煤3和油3,煤1和油2)、油页岩/煤层/油页岩共生组合(油2-煤1-油1)和油页岩/煤层共生组合(油上1和煤上1)。(2)在黄县断陷盆地古近系地层沉积充填序列中识别出两类三个性质不同的层序界面(SB1、SB2、SB3),其中李家崖组可划分出2个三级层序,各层序具有四元结构特点,即由低水位体系域、湖扩张体系域和早期高水位体系域、晚期高水位体系域组成。(3)黄县盆地古近系煤与油页岩共生组合主要在层序的低位体系域与湖侵体系域中发育,特别是在湖侵体系域中煤与油页岩组合类型丰富,主要与湖侵体系域复杂的沉积环境演化有关。

| Abstract: | The Huangxian Basin is an important sedimentary ore-forming process and sedimentary minerals hosting area. Using muhi- ple research methods of sedimentology, sequence stratigraphy and structural geology etc. carried out research on coal and oil shale asso- ciation types in Huangxian Basin, analyzed sedimentary environmental evolution of different association types under the sequence stratigraphic framework, thus is essential to coal and oil shale prospecting in the area. The result has shown： （1） coal and oil shale asso- ciation has four types in the area, that is oil shale/other deposits/coal paragenetic association （coal 4-mudstone-oil 4）, coal/oil shale paragenetic association （coal 3 and oil 3, coal 1 and oil 2）, oil shale/coal/oil shale paragenetic association （oil 2-coal 1-oil 1） and oil shale/coal paragenetic association （oil 1U and coal 1U）. （2） Two types of 3 distinct sequence interfaces （SB 1, SB2 and SB3） can be iden- tified in Paleogene strata sedimentary filling sequence in Huangxian fault basin, in which, the Lijiaya Formation can be divided into 3 third order sequences, each sequence has quaternary structure features, composed by lowstand system tract, lake expansion system tract, early highstand system tract and late highstand system tract. （3） Paleogene coal and oil shale paragenetic association in Huangx- Jan Basin was developed mainly in lowstand and lake transgression system tracts, especially abundant association types in the later, re- lated mainly with complex sedimentary environment evolution in lake transgression system tract. |
