莫里青断陷西部在始新世双阳组沉积时期发育ＮＥ，ＳＷ和ＮＷ方向三个浊积扇体，其中ＮＥ向浊积扇体仅发育于湖平面上升初期（双一段沉积时期），ＳＷ向浊积扇体在湖平面上升初期、上升早期和快速上升时期（双一，双二和双三段沉积时期）始终存在，而ＮＷ向浊积扇体形成于湖平面上升早期（双二段沉积时期），并一直持续到湖平面快速上升时期（双三段沉积时期）。目前在区内仅钻遇中扇水道、中扇过渡带和外扇沉积。
Three turbidite fans in the NE, SW and NW directions were developed during the deposition of the Eocene Shuangyang Formation in the western part of the Moliqing Fault. Among them, NE-turbidite fans developed only at the beginning of the rise of the lake plane At the beginning of the rising of the turbidite fan body at the lake level, the early rising and rapid rising periods (double-, double- and double-third-period depositional periods) always existed, while the NW-turbidite fan body formed at the early stage of lake level rise Depositional period), and lasted until the rapid rise of lake level (double-three deposition period). At present, only medium fan water channels, medium fan transitional zones and external fan deposits are encountered in the area.
