Other AbstractAround the mountain slopes of the eastem edge of Tibetan Plateau,there existed very wide、and thick deposited straturns of debris-soil.These deposition materials spread several huridred kilometers with depth of 100~200 m,and are of the composition structure of stickiness debris-flow with ground gravel in it.Some typical deposition sites and their forming times in western Sichuan. Province had been explored.The extraordinary wide distribution and great thickness,of these ground composition mean that,several catastrophic debris flows must happened in this area in Holocene epic.These events may be caused by the rapidly rising of air temperature after the Last Ice Age.ney can be classified as the debris-flow induced by glacier-snow melting.nis type of debris flows may happen as well in present, but with much small scale.
