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 else can I help you with?
How many types of igneous rocks are known?
Depends on how you categorize them. There are numerous types of rocks, and the number you come up with is just a representation of how specifically you classify them.
What are two types of igneous rocks?
Two types of igneous rocks are intrusive igneous rocks, which form from magma that cools and solidifies beneath the Earth's surface, and extrusive igneous rocks, which form from lava that cools and solidifies on the Earth's surface.

What types of rocks and minerals are there on mars?
there are all three types of rocks: igneous, metamorphic and sedimentary.
Who studies igneous rock?
Geologists study the rocks that compose the earth or other terrestrial planets. Mineralogists classify and name types of lava. Stone cutters study granite , which is an igneous rock.

What is the chemical property used to classify igneous rocks?
The chemical property used to classify igneous rocks is their mineral composition, specifically the type and relative abundance of minerals present in the rock. This information helps geologists differentiate between different types of igneous rocks, such as basalt, granite, and rhyolite.
What chemical property is most commonly used to classify igneous rock?
The mineral composition (silica content) is the chemical property most commonly used to classify igneous rocks. This can help differentiate between different types of igneous rocks, such as basalt, andesite, and granite.

What are three types of rocks?
igneous, sedimentary, metamorphic
What types of rocks are in a volcano?
igneous rocks
What other types of rocks are there other than igneous sedimentary and metamorphic?
Other types of rocks include volcanic rocks (such as basalt and pumice), hydrothermal rocks (like geyserite and travertine), and organic rocks (such as coal and limestone). These rocks form from specific processes or conditions that differ from the formation of igneous, sedimentary, and metamorphic rocks.
What types of rocks are apart of Igneous rocks?
Igneous rocks are rocks that are type of rock that forms from molten rock.
What sort of rocks can igneous rocks make?
Igneous rocks can be transformed not made but i think you are asking what types of rocks are igneous rocks well any rock that had once been lava/molten is an igneous rock and lava/molten comes from volcano.You might want to search on Google-types of igneous rocks or how can igneous rocks be transformed.

Name the three types of rocks?
Igneous, sedimentary, and metamorphic rocks are the three main types of rocks. Igneous rocks are formed from the cooling of molten rock, sedimentary rocks from the accumulation of sediment, and metamorphic rocks from the transformation of existing rocks under heat and pressure.
What are two types of igneous rocks?
Two types of igneous rocks are intrusive igneous rocks, which form from magma that cools and solidifies beneath the Earth's surface, and extrusive igneous rocks, which form from lava that cools and solidifies on the Earth's surface.
