摘要
文中阐述了Bohacs、Carroll等提出的陆相湖泊充填类型的划分理论,总结了陆相湖泊沉积的3种典型沉积组合:河流-湖泊相组合、波动深湖相组合和蒸发相组合,并对应各自的组合方式划分出3种湖泊充填模式:过充填湖泊、平衡充填湖泊和欠充填湖泊。笔者通过对中国松辽盆地中、晚白垩世时期泉头组—嫩江组的湖泊沉积相组合、层序地层特征等资料进行总结,并与Bohacs提出的湖泊填充模式划分进行对比,初步建立起松辽盆地当时的湖泊充填模式,进而对松辽盆地当时烃源岩埋藏和分布进行了分析和总结。
This article introduces the theory of lake-basin filling type classification,which was proposed by Bohacs.and Carroll.They had summarized many lake-basin lithofacies,and differentiated them into three typical associations：fluvial-lacustrine,fluctuating profundal and evaporative.Corresponding to these three lithofacies associations,we also differentiated the lake-basin into three filling types：overfilled lake-basin,balanced-filled lake-basin and underfilled lake-basin.By summarizing the lithofacies and sequence-stratigraphic characteristics of Quantou-Nenjiang Formations of Songliao Basin,China in the Mid-Late Cretaceous period,we compared Songliao Basin to this classification of lake-basin filling types proposed by Bohacs and built up a primary framework of Songliao lake-basin filling types in that period,so that we can go deeper to analyze and summarize the characteristics of their source rock distribution and organic matter burial.
