| Abstract: | The research of optical dating about modern strong earthquake sediments will be useful for understanding geological significance of paleoearthquake related sediments,improving dating precision and accuracy,and better understanding the law of earthquake occurrence.This article chooses some typical sediments related with 2008 Wenchuan earthquake,such as dammed lake deposits,floodwater deposits and ejected sands,to do optical dating of fine-grained quartz.Preliminary results from optical dating of fine-grained... |
