What Is The Difference Between Granitic And Basaltic Igneous Rocks

Although there are some similarities between basalt and granite there are also significant differences between these two rock types.

What is the difference between granitic and basaltic 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. Earth contains three kinds of rocks namely igneous rocks sedimentary rocks and metamorphic rocks basalt and granite are two types of igneous rocks. Examples of igneous rocks include granite basalt and diorite. The main difference between basalt and rhyolite is that basalt usually appears in dark colours while rhyolite usually appears in light colours.

There are three types of rocks on the earth s crust as igneous rocks sedimentary rocks and metamorphic rocks geologist made this classification based on the geological process that. Basalt is a dark colored fine grained igneous rock composed mainly of plagioclase and pyroxene minerals. One major difference between basaltic and granitic magma is their specific mineral contents. Both rhyolite and basalt are types of igneous rocks igneous rocks are usually found in two forms as intrusive and extrusive igneous rocks based on the method of formation.

Igneous rocks from the latin word for fire form when hot molten rock crystallizes and solidifies. The texture of igneous rocks can be referred to as phaneritic aphaneritic glassy or vitreous pyroclastic or pegmatitic. Basalt is a fine grained mafic igneous rock containing substantial amounts of dark colored silicates and plagioclase feldspar. Basalt is mafic while granite is felsic.

Igneous rocks are mostly formed beneath the earth s surface. Basalt is volcanic or extrusive forming at the surface while granite is plutonic or intrusive forming beneath the surface. The key difference between igneous rocks and sedimentary rocks is that igneous rocks are formed from molten liquid minerals called magma while sedimentary rocks are formed from lithification of existing rocks. The melt originates deep within the earth near active plate boundaries or hot spots then rises toward the surface.

Differences between basalt and granite. 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. All rocks of igneous origin consist of magma or molten earth that finds its way up to.
