摘　　要：扇三角洲沉积是伊通地堑主要沉积体系,地堑内发育水下水道型和水下水道—河口坝复合型扇三角洲,完整的扇三角洲序列包括进积、加积和退积3个阶段。在不同的构造沉降和沉积物供给条件下,形成了3种各具特色的扇三角洲序列样式,即缓慢沉降和低速沉积物供给型、快速沉降和低速沉积物供给型、快速沉降和高速沉积物供给型。The fan delta deposit is the main depositional system in Yitong graben where subaqueous channel type and subaqueous channel mouth bar complex type fan delta develop. A complete fan delta sequence consists of the progressive, the aggradating and the regressive phases. Three types of fan delta sequences can be determined in different tectonic subsidence and sediment input; they are slow subsidence and slow sediment input type, rapid subsidence and slow sediment input type, and rapid subsidence and rapid sediment input type.
