Title: Magnetic Fabric of Holocene Palaeo-Floods Events in Jianghan Plain
Abstract: Based on the study of sedimentary environment and chronology for Holocene sediments from Jiangling profile,Jianghan plain,this paper studies these events on palaeo-flood which took place in Jianghan plain since Holocene,using some marks of magnetic fabric parameters of flood sediment. The main results are as follows:(1) There are 55 large events of flood sediment since Holocene in Jianghan plain (excluding record data in history). (2) According to evolution,these events are divided into the stage of low frequency (9875-3000a BP),which is more stable and has an approximate period of mainly one thousand year and 500-625a,and the stage of high frequency (3000aBP~now),which is more frequent than the former,showing an increasing tendency and has a period of frequent occurrence of mainly 300-200a.
