The basic processes involves in igneous rock formation are; 1. Melting (Magma, formation of molten substance). 2. Volcanicity (Eruption, movement of magma). 3. Cooling (Change in temperature). 4. Crystallization (Mineralization, formation of crystals and minerals). 5. Solidification (Consolidation into a solid mass to form igneous rock).

A certain igneous rock contains about 25 percent dark silicate minerals The remainder of the rock is mostly plagioclase feldspar What type of composition does tthis igneous rock have?
ultramafic
Why does earth have more sedimentary rock than metamorphic rock or igneous rock?
Most Earth rock is igneous or metamorphic even though visible surface bedrock is mostly sedimentary. Of the total Earth rock volume, only a tiny fraction is sedimentary.
How tall is Mitchell hope?
mostly likely 5'5..
Explain why geologists say that all rock was originally igneous rock?
The oceanic plates of the crust are almost entirely basalt, an igneous rock. The continental crust in underlain by mostly granites, also igneous.
Is coal extrusive igneous rock?
No, coal is a sedimentary rock composed mostly of the remains of ancient vegetation (except for anthracite coal which is a metamorphic rock, see image above)..
Which rock is mostly likely a sedimentary rock?
One showing an igneous nature.
Which rock is mostly likely a non sedimentary rock?
One showing an igneous nature.
Does the sun driver the processes that form igneous and metamorphic rocks?
No. Heat from the interior of the Earth trying to reach the surface drives lithospheric plate movements which are mostly responsible for the formation of igneous and metamorphic rocks.
What does pyroclastic?
Pyroclastic describes a rock formation mostly consisting of rock fragments from volcanoes or crushed during an eruption.
What type of formation is a mid-oceanic ridge?
Its mostly a basaltic formation, caused as a result of ferromagnetic magmatic emergence at zones of seafloor spreading during oceanic-oceanic divergence.
What does earth's crust consist mostly of?
Igneous rock.
What does the Earths crust mostly consist of?
Igneous rock.
What is the Continental crust composed of mostly?
Igneous rock.
What are the characteristics of geologic formation?
Formations consist of strata of specific origin, type, or characteristics. Mostly sedimentary, a formation could also be of metamorphic or igneous origin. One of the most famous formations is that of the Burgess Shale, a treasure trove of Cambrian age fossils, located in the Canadian Rockies.
How do you classify igneous rocks from other types of rock?
Igneous rocks are identified by first looking at the color index. Felsic igneous rocks contain mostly potassium feldspar. Intermediate igneous rocks contain mostly plagioclase feldspar. Mafic igneous rocks contain pyroxene, olivine, and plagioclase feldspar. Ultra mafic igneous rocks contain mostly olivine. Then igneous rocks are identified based on texture. For example, the texture of igneous rocks can be aphanitic, pegmatitic, phaneritic, glassy, vesicular, etc.
What igneous rock contains mostly pyroxene and olivine?
Ultramafic igneous rocks are comprised mostly of olivine and pyroxene. Examples include peridotite (pegmatic and porphyritic) and komatite.
What does pyroclastic surge mean?
Pyroclastic describes a rock formation mostly consisting of rock fragments from volcanoes or crushed during an eruption.
