Something like the Cliffs of Dover maybe? That's from sea level fall isn't it (haven't looked into it specifically but I know it made of products of marine organisms, but maybe it was pushed up tectonically originally). Here they talk about a lose landmass caused by accumulated glacial remains of the last ice age. So it would have likely mostly accumulated originally during a period sea rise.
