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-

Types of Quarries

Hard rock. Natural sand. Natural sand and gravel. Sandstone (building stone and sand) Marine/ocean. Limestone. Quarries have operated for thousands of years. There is evidence of quarries dating back over 200,000 years, when pre-historic man-made improvised tools. For a comprehensive Glossary of Quarrying Terms CLICK HERE.
