| Research Abstract |
We established how to observe and describe high-quality undisturbed drilled cores using methods and knowledge of structural geology, and consequently obtained criteria to differentiate nontectonic faults and tectonic faults. We clarified the relationship between the development of foliation and gravitational rock deformation and the development processes from gravitational slope deformation to first-time landslide.
We simulated the subsurface gravitational slope deformation that have been obtained by high-quality drilled cores by using finite difference methods, demonstrating that the internal stress strain conditions in the slope change according to the river incision forming the shear zones, which have been identified in the nature.
