Igneous rock, any of various crystalline or glassy rocks formed by the cooling and solidification of molten earth material. Igneous rocks constitute one of the three principal classes of rocks, the others being metamorphic and sedimentary.
The types of rock: igneous, metamorphic and sedimentary
Rocks and minerals . A jumble of ceaselessly recycled igneous, sedimentary, and metamorphic rocks makes up the earth's surface. Igneous rock (granite, gneiss) forms when molten rock cools. The Canadian Shield's igneous base abounds in copper, gold, iron, and nickel.
Igneous rocks are found just about anywhere rock has melted because of tectonic activity and where ever volcanic rock has flowed over, or been spattered over, older rocks. The word "ignite" and "igneous have similar roots." That and $2 will get you a tall coffee at Starbuck's.

Amphibole is a rather common mineral in all igneous rocks, however, it is only abundant in the intermediate igneous rocks. It occurs as slender needle-like crystals (see image to the left). It has good cleavage in 2 directions and hence has a stair-step appearance under a binocular microscope. It is often confused with biotite and pyroxene.
Where can igneous rocks be found? How are they found? - Quora
It is found mostly in dark colored igneous rocks. Calcite and Dolomite: The color is usually white, but can be other colors when impure. Crystal grains show flat shiny faces, often shaped like parallelograms.
Minerals such as pyrite and metallic copper may be found within the sedimentary rock. Igneous Appalachian rocks include pegmatite, alaskite, mica and feldspar formed from molten magma. Rocks of dunite, and olivine containing peridotite are found in the southern ranges.

Igneous rocks are classified into two groups depending upon where the molten rock solidifies: extrusive or intrusive. Key Terms . Felsic: Derived from the words feldspar and silica to describe an igneous rock having abundant light-colored minerals such as quartz, feldspars, or muscovite.
For instance, a rock called pegmatite is formed by the crystallization of magma enriched with water in the veins of other rocks, and may contain beryl, tourmaline and topaz. Igneous rocks are divided into two types-- volcanic rock (extrusive) and plutonic rock (intrusive) -- …
This type of igneous rock is typically found in continental settings where magmas have incorporated granitic rocks from the crust as they rise from the mantle. It tends to make lava domes when it erupts.

Igneous Rocks. Igneous rocks are those that solidify from a molten or partially molten state. These rocks are characterized as either extrusive or intrusive. Extrusive Rocks. Extrusive igneous rocks solidify from molten material that flows over the earth's surface (lava).

GEOLOGY. The geologic history of Texas is recorded in rocks found in outcrops throughout the state and in rocks penetrated by boreholes drilled primarily in the search for oil and natural gas. These rocks indicate that Texas has undergone a long and dynamic history of igneous activity, structural deformation, and sedimentary processes.
Igneous rock is formed by the cooling and crystallization of magma or lava. A collection of igneous rocks. Igneous rock is formed by the cooling and crystallization of magma or lava.

Igneous Rocks | Pictures of Intrusive and Extrusive Rock Types
Igneous rocks can be distinguished from most regional metamorphic rocks by the lack of foliation (layering) in igneous rocks. Unfoliated metamorphic rocks lack igneous textures and usually contain minerals not found in igneous rocks. Granite may look like gneiss at first glance, but granite has no layering, no preferred orientation of the minerals.
Igneous rocks can be found wherever volcanic activity has brought, or is bringing, magma, ash etc. to the surface where they form basalt, tufa etc. There are also igneous rocks that form underground, and have become exposed by erosion, eg. granites, intrusive dykes.
Igneous Rocks. Igneous Rocks are the most primitive of rocks – they come directly from molten rock and crystallize in varying ways to become rocks. Since the other types of rocks (metamorphic and sedimentary) are derived from igneous rocks to start with – it is important to know the basics of where the source rock came from.
