摘要：

松辽盆地白垩纪微体古生物丰富,分布广泛,演化迅速。介形虫划分为15个组合带,孢粉5个组合带,轮藻4个组合带。其中某些组合带与地震波组有一定的对应关系,可作为地层划分对比的依据。对应关系为两类:一类与构造运动密切相关,为T41、T31和T30波组,均为划统的界面,与生物演化、建造类型和古气候的变化一致。另一类则是岩性的反映,为T1和T2波组,往往是区域对比标准反射层。

Abstract:

The Cretaceous microfossils in the Songliao Basin are characterized by abundance,wide-spreading and rapid evolution. Ostracods could be divided into 15 assemblage zones,sporo-pollen 5 assemblage zones, charophytes 4 assemblage zones. Some of the assemblage zones bear certain correspodent relationship to seismic wave groups, and could be used as the basis for stratigraphic division and correlation. The correspondences may be divided into two kinds:1. as boundary surfaces of series such as T41, T31 and T31 wave groups which are related to tectonic movement, and coincided with the evolution of organisms, formation types and paleoclimates; 2. as lithologic revelation for example T1 and T2 wave groups are usually the standared reflective horizons for regional stratigraphic correlation.
