中文摘要	受气候控制的洪水事件沉积因其短暂性、广布性和周期性等特征,具有相对的等时效应,可以作为地层划分和对比的标志层。通过分析不同规模周期下的事件沉积和正常沉积特征,并结合基准面旋回理论,识别出济阳坳陷惠民凹陷临盘地区始新统孔店组一段沙河街组四段下亚段红层短期、中期和长期三个级次的基准面旋回特征,短期旋回以洪水期和间洪水期内发育的不同类型沉积微相组合为特征,中期旋回以发育一套完整的洪水期间洪水期沉积为标志,长期旋回则以多个中期旋回组成的地层叠加为特征;以此为依据将惠民凹陷临盘地区孔店组一段沙河街组四段下亚段划分为5个长期旋回、16个中期旋回及若干个短期旋回层序,并对第一个长期旋回进行了精细层序地层对比,在此基础上建立了干旱气候控制下的红层层序的划分和对比模式。
英文摘要	Because of the characteristics of transience,widespread presence,periodicity and isochronisms,flood deposition that under the control of climate can be used as a key bed in stratigraphic division and correlation.By identifying event deposit and normal deposit under different scale periods and combining the theory of base-level cycle,the writers classified the 1st Member,Kongdian Formationthe lower part of 4th Member,Shahejie Formation,Eocene,in the Linpan area,Huimin Sag in Jiyang Depression,Northern Shandong,into three order cycle sequences: short-term,medium-term and long-term base level cycle sequences.Short-term base level cycle was characterized by combination of different types of sedimentary micro-facies which formed in the course of flood period and inter-flood period;medium-term cycle was characterized by an integral deposit that consist of flood deposit and inter-flood deposit;long-term cycle were characterized by stacking of several medium-term cycle sequences.Writers divided the 1st Member,Kongdian Formationthe lower part of 4th Member,Shahejie Formation,Eocene,in the Linpan area,Huimin Sag,Jiyang Depression,into 5 long terms,16 medium terms and a certain number of short terms of cycle sequences,performed fine stratigraphic correlation to the first long term,then built up the sequence division and correlation model of redbeds under the control of arid climate after the researches all above.
