What is the difference between a rock and a mineral?

A mineral is a naturally occurring inorganic element or compound having an orderly internal structure and characteristic chemical composition, crystal form, and physical properties. Common minerals include quartz, feldspar, mica, amphibole, olivine, and calcite.A rock is an aggregate of one or more minerals, or a body of undifferentiated mineral matter.

CLASSIFICATION // CHARACTERIZATION OF SOME ROCK

Knowing the rock type and rock material hardness, it is possible for the experienced engineer or engineering geologist to make fairly accurate estimates on rock material strength. These can be readily verified by uniaxial compressive strength or point load tests. A simple estimate can be made from the field test in Table 5.
