What Is The Difference Between Basaltic And Granitic Magma

Andesitic lava is an example of a high viscosity lava whereas balastic lava has a low.

What is the difference between basaltic and granitic magma.

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. Simply put rhyolitic lava is more viscous than basaltic lava. A basaltic pond of magma becomes trapped below continental crust and partially melts this silica rich crust into a granitic magma. Basaltic magma is acidic fluid rich in iron and magnesium but poor in silica.

Other articles where granitic magma is discussed. Granitic magma is basic viscous a high melting point with a high percentage of silica. Earth contains three kinds of rocks namely igneous rocks sedimentary rocks and metamorphic rocks basalt and granite are two types of igneous rocks. Granitic or rhyolitic magmas and andesitic magmas are generated at convergent plate boundaries where the oceanic lithosphere the outer layer of earth composed of the crust and upper mantle is subducted so that its edge is positioned below the edge of the continental plate or.

However there are a number of readily accessible and better descriptions available. 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. Basalt is volcanic or extrusive forming at the surface while granite is plutonic or intrusive forming beneath the surface. It has a granite like character.

Basalt on the other hand has a smooth texture from rapid cooling usually by water. Please consult geology rocks and minerals or how do basaltic r. Granite is an intrusive rock that is formed when magma cools inside the crust. What are the differences between basaltic and andesitic lava.

This slow cooling gives time for crystals to grow making it more coarsely grained than an extrusive rock. Differences between basalt and granite although there are some similarities between basalt and granite there are also significant differences between these two rock types. This coarse grain makes granite a favorite of rock climbers. All rocks of igneous origin consist of magma or molten earth that finds its way up to.
