Excursion at the Cretaceous Sanchu Group
Students studying field geology, for example, sedimentology, stratigraphy, and tectonics, need to have three dimensional view and even four dimensional vision including the geological history of the terrane they are working on. We have nice and solid exercise to establish those visions in the Cretaceous Snachu graben and the Neogene Chichibu basin.
