摘要
在利用孢粉、地震等资料划分辽东湾古近纪等时地层格架的基础上,通过建立孢粉气候信息函数的方法反演辽东湾古近纪温度和湿度变化曲线,将其划分为1个一级气候旋回,4个二级气候旋回和10个三级气候旋回,结合湖平面变化曲线分析气候旋回的作用,得出气候与湖平面变化相关性高、控制部分层序和沉积发育以及对烃源岩分布的绝对控制作用。
Isochronous sequence stratigraphy is identified by using palynological and seismic data.Through the establishment of palynological climatic information function,the temperature and moisture curve of Paleogene in Liaodong Bay depression is drawn.Based on temperature and moisture feature,Paleogene is divided into 1 first-order,4 second-order and 11 third-order climatic cycles.The climate swing function is analyzed by combining the lacustrine level change curve.From the analysis,it can be concluded that the climate has a close relationship with the lake level.It can control sequence,sedimentary and source rock.
