A type of intrusive igneous rock with larg crystals?
Basically, all intrusive igneous rocks have large crystals. Because they are intrusive, they take a long time to cool down, and so there is a lot of time for crystal growth. That said, the biggest categories of intrusive igneous rocks are: Peridotite (ultramafic) Gabbro (mafic) Diorite (Intermediate) Granite (silicic/felsic) Granite is the most common one in the continental crust.
What kind of rocks make up the most of the igneous rocks?
Basalt and granite are the most common types of rocks that make up igneous rocks. Basalt is a fine-grained volcanic rock, while granite is a coarse-grained intrusive rock.
What texture would most unlikely occur in a extrusive igneous rock?
A texture that would most unlikely occur in an extrusive igneous rock is a coarse-grained or phaneritic texture. This texture, characterized by large, visible crystals, typically forms in intrusive igneous rocks where the magma cools slowly beneath the Earth's surface. In contrast, extrusive igneous rocks cool quickly at or near the surface, resulting in fine-grained or glassy textures, such as aphanitic or vitreous. Consequently, the formation of large crystals in extrusive rocks is highly improbable.
Are felsic rocks usually intrusive or extrusive?
Felsic rocks are usually intrusive, meaning they form below the Earth's surface from magma that cools and solidifies slowly. This slow cooling allows minerals such as quartz and feldspar to crystallize and form coarse-grained textures commonly seen in intrusive rocks like granite.
What is the most common type of intrusive rock?
The most common type of intrusive rock is granite. Granite forms from the slow cooling of magma deep underground, resulting in a coarse-grained texture with visible crystals of minerals such as quartz, feldspar, and mica. It is widely distributed on Earth's continental crust and often used in construction and sculpture due to its durability.
What are the most common intrusive and extrusive rocks?
Some common intrusive rocks include granite, diorite, and gabbro, while common extrusive rocks include basalt, andesite, and rhyolite. Intrusive rocks form beneath the Earth's surface from slowly cooling magma, while extrusive rocks form from rapidly cooling lava on the Earth's surface.
What rocks are formed belows Earth's surface?
Most sedimentary rocks, most metamorphic rocks, and intrusive igneous rocks.
How can you determine if a igneous rock has had an intrusive or extrusive origin?
== Grain size. Most intrusive igneous rocks will have visible crystals. Crystals in most extrusive igneous rocks are not easily visible.

Is basalt the most common intrusive rock?
Yes, Basalt is the most common extrusive rock
What are two types igneous rocks?
Granite and basalt are the most common types of igneous rock. Igneous rock types, or classifications, also include those that are intrusive and extrusive. Intrusive igneous rock is formed from the solidification of slow cooling magma below the surface. Extrusive igneous rock is formed for the solidification of rapidly cooling lava at or near the surface.
What is the most common type of intrusive?

Is basalt a most common intrusive rock?
No. Basalt is the most common extrusive igneous rock.
