Height difference between the crown and the toe of rupture surface of Zhaizicun landslide along the right bank of Jinsha River is 638 m, with about 2.5×108 m3 total rock displaced. The giant rock landslide complex caused serious landslide-damming and the crest of the residual landslide dam with a volume of 180×104 m3 on the left bank is 118 m above the river. Deposits of Zhaizicun landslide-dammed lake is a representative case of the Xigeda Formation. Deposits of landslide-dammed lakes compose >80% of the Xigeda Formation and landslide dammed lake genesis model for the Xigeda Formation may reasonably explain various its plane outcrop shapes, profile features, the genesis relationship between the Xigeda Formation and fluvial gravel beds, highly dependence on rivers, dimension difference and space discontinuity among different regions. oft-com:office:office" />
