Table 1. 5 Geological classification of metamorphic rocks It has been estimated that the earth's crust is made up of about 95% igneous rocks，about 5% sedimentary rocks and an insignificant proportion of metamorphic rocks. This does not， however，give a completely true picture of th...

A functional,diagnostic classification of fault rocks is introduced, based on our experience from investigation and construction of rockstructures such as dams, slopes andtunnels, and consideration of the results of recent research.Gunter Riedmüller...

Moreover, it has been difficult to distinguish between rocks fragmented by landslide movement and fault breccia. We examined the detailed geology of high-quality boring cores of a landslide on the Shimanto Belt in Kyushu and nearby outcrops. The fault breccia near the landslide body was found ...

The geologic time scale is the “calendar” for events in Earth history. The enumeration of those geologic time units is based on stratigraphy, which is the correlation and classification of rock strata. The fossil forms that occur in the rocks provide the chief means of establishing a geologic...
