What Is Basalt Extrusive Vs Granite Intrusive

An intrusive rock is formed when magma solidifies below the surface of the earth.

What is basalt extrusive vs granite intrusive.

Examples of intrusive igneous rocks are diabase diorite gabbro granite pegmatite and peridotite. Granite the equivalent of its extrusive volcanic rock type rhyolite is a very common type of intrusive igneous rock. They also have numerous differences. Granite is a great example of.

It most commonly forms as an extrusive rock such as a lava flow but can also form in small intrusive bodies such as an igneous dike or a thin sill it has a composition similar to gabbro the difference between basalt and gabbro is that basalt is a fine grained rock while. These rocks include andesite basalt dacite obsidian pumice rhyolite scoria and tuff. Basalt is an extrusive igneous rock whereas granite is an intrusive ingenuous rock.

On the other hand granite occurs above the ocean and makes up much of continental crust. With the insulation of the ground the cooling process is a lot slower allowing for the formation of larger mineral crystals.

Basalt is a dark colored fine grained igneous rock composed mainly of plagioclase and pyroxene minerals. If found on the surface it will be in smaller particles. Some cool so quickly that they form an amorphous glass. Its principal minerals are feldspars quartz and mica.

Extrusive igneous rocks erupt onto the surface where they cool quickly to form small crystals. It contains more than 68 weight of silica in composition and is granular and coarse grained in texture. Granite is the best example of intrusive rocks whereas the basalt is a fine example of extrusive rocks. Determination of intrusive and extrusive igneous rocks.

Granite is an intrusive type of igneous rock also since it is intrusive it cools very slowly and forms large crystals and coarse large grained igneous rock. One other difference between basalt and granite pertains to the way these two types of rocks split when putting under pressure. We have moved all content for this concept to for better organization. Basalt is extrusive mafic and common throughout the solar system whereas granite is intrusive felsic and common only on earth.

Basalt and granite are similar in the they are both igneous silicate rocks and common on earth.
