- a. An aggregate of one or more minerals, e.g., granite, shale, marble; or
a body of undifferentiated mineral matter, e.g., obsidian, or of solid
organic material, e.g., coal. AGI
b. Any prominent peak, cliff, or promontory, usually bare, when considered
as a mass, e.g., the Rock of Gibraltar. AGI
c. A rocky mass lying at or near the surface of a body of water, or along
a jagged coastline, esp. where dangerous to shipping. AGI
d. A slang term for a gem or diamond. AGI
e. Strictly, any naturally formed aggregate or mass of mineral matter,
whether or not coherent, constituting an essential and appreciable part of
the Earth's crust. Ordinarily, any consolidated or coherent and relatively
hard, naturally formed mass of mineral matter; stone. In instances, a
single mineral forms a rock, as calcite, serpentine, kaolin, and a few
others but the vast majority of rocks consist of two or more minerals.
f. A local term used in New York and Pennsylvania for the more massive
beds of bluestone that are not jointed and are, therefore, well-suited for
structural purposes.
g. In the geological sense, any natural deposit or portion of the Earth's
crust whatever be its hardness or softness, but used by miners to denote
sandstone. TIME
h. In geology, the material that forms the essential part of the Earth's
solid crust, and includes loose incoherent masses, such as a bed of sand,
gravel, clay, or volcanic ash, as well as the very firm, hard and solid
masses of granite, sandstone, limestone, etc. Most rocks are aggregates of
one or more minerals, but some are composed entirely of glassy matter, or
of mixtures of glass and minerals. Hunt
i. In the Lake Superior region, crude copper ore as it comes from the
mines. The concentrate obtained is called mineral, and contains about 65%
metallic copper.
