Chapter 4 Engineering Classification of Rock Materials

The rock unit is the basic mapping unit for the rock material field classification (RMFC) system. It is de-fined as a body of rock that is identified in the field and mapped according to measurable or otherwise describable physical properties or features at a scale useful for project analysis. A rock unit is consistent in its mineralogical composi-
