摘要
束鹿凹陷是一个典型的单断型箕状凹陷,在古近系沉积过程中,东、南、西三面的古生界碳酸盐岩和前古生界变质岩为凹陷内古近纪沉积提供了物源。受控盆边界断层———新河大断层活动的影响,束鹿凹陷古近纪的构造发育经历了湖盆形成期、强烈断陷期和断陷回返上升期。在束鹿凹陷古近纪的盆地断陷演化过程中,不同阶段构造发育特征和物源、古地形等的综合作用,导致了盆地充填过程及沉积类型的特殊性。
Shulu Depression is a typical half - graben dustpan - like depression. During the course of sedimentation of Paleogene, carbonate of Paleozoic and metamorphic rock of pre - Palaeozoic provided source for the depression. Structure of Shulu Depression in the Paleogene experienced such stages as basin formation, intense fault depression and return of rift because of the activity of Xinhe fault,which is the border fault controlling basin. The compositive influences of structure,material origin and paleotopography at different stages resulted in the particularity of basin infilling and sedimentation type in evolution of the basin in the Paleogene.
