Amphibolite
|
A heavy, dark colored, medium to coarse grained rock, formed from other rocks as they come into contact
with a molten rock mass.
|
|
|
Basalt
|
A very fine grained extrusive igneous rock with less that 20% quartz. Extrusive formed from the rapid
cooling of basaltic lava exposed at, or very near, the surface.

Basalt

|
Caliche
|
A hardened natural cement of calcium carbonate binding other materials such as gravel, sand, clay and silt.
Occurs generally in arid or semi-arid regions of the western USA.

Cement
|
A powder of alumina, silica, lime, iron oxide, and magnesium oxide burned together in a kiln and finely
pulverized and used as an ingredient of mortar and concrete.

Crude Oil
|
Petroleum as it occurs naturally, as it comes from an oil well, or after extraneous substances (as
entrained water, gas, and minerals) have been removed.

Dolomite
|
Also known as "dolostone", is a sedimentary rock composed primarily of the mineral dolomite, CaMg(CO2)3. It
is found in sedimentary basins worldwide. It is thought to form by the alteration of lime mud and limestone
by magnesium-rich groundwater.

Gabbro
|
A heavy, coarse grained rock, composed of mostly dark colored minerals with little quartz, formed as magma
cools below the surface of the earth.
|
Basalt
|
|
Gneiss
|
A common medium to coarse grained and widely distributed type of rock formed by metamorphic processes from
pre-existing formations that were originally either igneous or sedimentary rocks. It is often identified by
alternating darker and lighter colored bands, called "gneissic banding" which describes texture, not
composition.
|
Granite
|
|
Granite
|
An igneous, light colored, coarse grained rock, composed mostly of quartz and feldspar, formed from a body
of magma as it cools.

A widely distributed mineral consisting of hydrous calcium sulfate that is used especially as a soil
amendment and in making plaster of paris.

Hot Mixed Asphalt
|
Hot Mixed Asphalt is a mixture of mineral aggregate and liquid asphalt binder mixed together in specific
proportions at elevated temperatures then placed and compacted prior to cooling.

Limestone
|
A fine to coarse grained sedimentary rock, formed from transportation and compaction of calcium carbonate
sediment from the shells of sea organisms or by the direct chemical precipitation of calcium carbonate.
|
Limestone/Dolomite
|
|
Limestone Rock Asphalt (LRA)
|
A porous limestone, once saturated with petroleum, that has since evaporated, leaving behind dark asphalt
tar within the voids of the rock.

Pegmatite

Sand and Gravel
|
A naturally occurring granular material ranging in size from 0.002 to 4 inches being formed as a result of the erosion and weathering of rocks. Composition is dependent on the source material.

Syenite
|
A coarse-grained intrusive igneous rock that has basically the same general composition as granite but with the quartz either absent or present in relatively small amounts.
|
Granite
|
|
TrapRock
|
Light to dark colored, fine grained rock, formed as molten rock flows out of the earth as lava and is cooled quickly. "Trap rock" is not a geological term. It is a term used in the mining industries to refer to any number of dark-colored igneous rocks that are crushed and used, primarily, for road construction. The most common rock types of trap rock are gabbro and basalt.
