There are aiguilles named “Cuernos del Paine” which abraded by glacier in center part of Paine National Park located in Patagonia in place in which it entered from the south end Strait of Magallanes to inland a little in South America.
The white colored middle part of the aiguilles is composed of granitic batholith.
The black colored upper and lower part of the aiguilles are composed of hornfels have undergone thermal metamorphism of sedimentary rocks in the Mesozoic.



Limestone open-cut mining of Sumitomo Kogyo located at Matsudate district, HachinoheCity, Aomori prefecture. It is called Hachinohe Canyon alias. The height between ground surface and deepest part (-135m under sea level) is approximately 240m, and maximum diameter at north-south direction and east-west direction are about 1800m and 800m respectively. Big size bivalve fossil of Megadoron in 200 Ma was occurred in this area.



Imbricate structure formed within the compression ridge of the front of landslide movement mass.This imbricate structure of the compression ridge was confirmed in the drainage trench excavated at the front of landslide movement mass at Nakashibetsu-cho, Hokkaido.The movement mass is composed of mainly tephra from Mashu volcano in the latter Pleistocene to Holocene.Left side of this photo will be head side of movement mass and right side will be front side.4 thrust faults are observed at center of this photo, it is assumed that each thrust block wes piled in order from front side (right side of photo), by the observation result of displacement of each fault.
Moreover, it is assumed that this structure was continuously formed by one time activity of landslide, because of comparatively well reserved beds before deformation.

Photo of the Triassic-Cretaceous sedimentary beds weakly folded of Helbet zone and lower granite gneiss body in the Europe Alps, from view point of Brevent (EL. 2,525m) in Chamonix, Switzerland. This granite gneiss metamorphosed in Variscan orogeny will be same body with the rock mass of Mt. Mont Blanc. Small slip plane can be found on the boundary between upper Triassic sedimentary beds and lower granite gneiss body in the field excursion.



Because the Hakkouda Tunnel on the route of Tohoku Shinkansen was excavated near an old mining area, there was concern about the environmental impact to the surrounding area made by the acid water due to the decomposition of sulfide minerals such as pyrite and by the elution of heavy metal that were contained in the rock muck derived from the excavation work. In the Hakkouda Tunnel project, therefore the rock muck which could cause such water pollution was disposed into a controlled disposal site.
These photographs show the controlled disposal site under construction and after its completion. The upper left photograph shows the situation of the installing impermeable liner on the bottom base of disposal site, and upper right photograph shows the temporary capping executed before snowfall period. The middle left and lower left photographs show the fairing of the disposal and the execution of the permanent capping respectively. The photograph at the lower right shows the final shape of the whole disposal site including the controlled disposal site.
