Optical dating of river terrace sediments from Kanto plains, Japan
Autor: Daniele Questiaux, Ryuta Hataya, Kazuhiro Tanaka, Nigel A. Spooner
Publikováno v: Quaternary Science Reviews. 20:825-828
Optical dating of river terrace sediments has been carried out in a test of the methodology for luminescence age determination of river terrace formation over the last 100 ka. In this study, samples were collected at river terraces, whose ages were e

Publikováno v: Doboku Gakkai Ronbunshu. 2000:55-72
一般に砂礫地盤は, 砂地盤に比べて地震時液状化が生じにくいと考えられている. ところが, 最近では地震後の被害調査や考古学的な発掘調査の際に砂礫の液状化事例がいくつか発見され
