摘要
在研究该区若性、古生物、古厚度、河流类型、古构造及英台扇三角洲复合作纵横相序等特征基础上,认为构造、坡度、气侯、物源、辫状河水系、受水湖盆能量等条件是控制英台扇三角洲复合体的必要因素。而携带碎屑物质的洪水期突发性河流过程和湖盆过程之间的相互作用是形成英台扇三角洲复合作的复合水动力机制。并从控制条件和水动力机制的综合作用观点,阐述了坳陷古湖盆扇三角洲的沉积过程和沉积理论。
Based on the characteristics of lithotogy, palaeontology, palaeothickness, types of
rivers, palaeostructure as well as vertical and horizontal facies' sequences of Yingtai fan
delta complex, we believe that the structure, slope, climate, provenance, water sys-
tems of braided rivers and the basin's water energy are the neccessary factors that con-
trol the Yingtai fan delta complex, whereas the interactions between the abruptly detri-
tal river's processes during flood and basin's processes are the hydrodynamic mechanism
that formed the Yingtai fan delta complex. According to this, the depositional processes
and depositional theory have been summarized on view of the comprehensive interactions
between the controlling conditions and the hydrodynamic mechanism.
