摘要
针对松辽盆地周边石炭系地表出露分散且多呈断片产出的复杂特点 ,运用生物化石、岩性特征、地层接触关系综合分析方法 ,建立了地层间的相互层位和对比关系 .下石炭统为海相碎屑岩及中酸性岩组合 ;上石炭统下部缺失 ,上部为陆相碎屑岩及酸性岩组合 .
In the Carboniferous in Songliao basin peripheral earth's surface, outcrop scatters about and broken rocks are more complicated. The mutual stratigraphic horizon and correlation is established by comprehensive analysis of the living creature fossil, rock characteristic and stratigraphic contact relation. Lower Carboniferous is composed of sea facies fragments and mid-acidic component igneous rock. Upper Carboniferous is composed of land facies fragments and acidic component igneous rock.
