What Is The Difference Between Granitic And Basaltic Igneous Rocks

The melt originates deep within the earth near active plate boundaries or hot spots then rises toward the surface.

What is the difference between granitic and basaltic igneous rocks. Basalt is volcanic or extrusive forming at the surface while granite is plutonic or intrusive forming beneath the surface. One major difference between basaltic and granitic magma is their specific mineral contents. The main difference between basalt and rhyolite is that basalt usually appears in dark colours while rhyolite usually appears in light colours. Basalt is a fine grained mafic igneous rock containing substantial amounts of dark colored silicates and plagioclase feldspar.

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. Igneous rocks are divided into two groups intrusive or extrusive depending upon where the molten rock solidifies. Examples of igneous rocks include granite basalt and diorite. Basaltic magma contains between 45 and 55 percent silicon dioxide and is high in magnesium iron and calcium while granitic magma contains between 65 and 75 percent silicon dioxide and only small amounts of those minerals.

Difference between granitic rhyolitic felsic basaltic mafic granite is a felsic coarse grained igneous rock composed of light colored silicates quartz and potassium feldspar. Although there are some similarities between basalt and granite there are also significant differences between these two rock types. The texture of igneous rocks can be referred to as phaneritic aphaneritic glassy or vitreous pyroclastic or pegmatitic. Basalt is a dark colored fine grained igneous rock composed mainly of plagioclase and pyroxene minerals.

Differences between basalt and granite. Igneous rocks are mostly formed beneath the earth s surface. 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.

Earth contains three kinds of rocks namely igneous rocks sedimentary rocks and metamorphic rocks basalt and granite are two types of igneous rocks. 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. Igneous rocks from the latin word for fire form when hot molten rock crystallizes and solidifies.
