The fan deltaic body can be divided into three subfacies, named fan delta plain, fan delta front and pro-fan delta.
扇三角洲沉积体明显地可划分为：扇三角洲平原亚相、扇三角洲前缘亚相和前扇三角洲亚相。
The general sedimentary characteristics indicate that shore-shallow lacustrine deposits are the main types, while flood plain, delta and fan delta occurred mainly along the basin margin.
沉积相总体特征以滨浅湖沉积为主，而在研究区周缘则多发育河流泛滥平原、三角洲和扇三角洲沉积。
