Both Basalt And Granite Are Examples Igneous Rocks

On this basis we are going to look at the commonly identified types of igneous rocks both.

Both basalt and granite are examples igneous rocks.

The two main categories of igneous rocks are extrusive and intrusive. Examples of igneous rocks. Extrusive igneous rocks erupt onto the surface where they cool quickly to form small crystals. Examples of such kind of rocks include pumice basalt or obsidian.

There are more than 700 known types of igneous rocks and most of them are formed under the earth s crust since volcanic events are not all that frequent. Volcanic rocks are also called extrusive igneous rocks as opposed to intrusive igneous rocks. Both are igneous rocks which means that they cooled from a magma the earth gets very hot just below the surface and there is lots of liquid rock. Basalt and granite actually have quite a bit in common.

Earth contains three kinds of rocks namely igneous rocks sedimentary rocks and metamorphic rocks basalt and granite are two types of igneous rocks. The key difference between basalt and granite is that basalt is mostly occurring on ocean floors while granite is in the crust of the earth in all continents. All rocks of igneous origin consist of magma or molten earth that finds its way up to. Some cool so quickly that they form an amorphous glass.

These rocks include andesite basalt dacite obsidian pumice rhyolite scoria and tuff. For example two rocks from identical magma can become either rhyolite or granite depending on whether they cool quickly or slowly. Igneous sedimentary and metamorphic rocks have undergone little change since earth formed false. They also have numerous differences.

According to bowen s reaction series which mineral crystallizes at the lowest temperature. The most common rock type in earth s crust is igneous. In geology a pluton is a body of intrusive igneous rock also called plutonic rock that is crystallized from magma slowly cooling below the surface of the earth although pluton is a general term to describe an intrusive igneous body there has been some confusion around the world as to the definition of a pluton. Intrusive rocks are formed.

Pluton has been used to describe any non tabular intrusive body and batholith. The classical example here is basal t which can have many small crystals or very few large ones. It forms from subterranean magma chambers that cool and harden beneath the surface and then become exhumed and exposed at the surface. Basalt and granite are examples of metamorphic rocks false.

Excluding the rocks between my ears i d have to say that basalt and granite have the honor of being the most important rocks in the crust. Examples of intrusive igneous rocks are diabase diorite gabbro granite pegmatite and peridotite. For example granite and basalt are both igneous rocks with different chemical composition and structure and therefore different weathering rates. Basalt and granite are similar in the they are both igneous silicate rocks and common on earth.
