Basaltic And Granitic Magma Differences
Earth contains three kinds of rocks namely igneous rocks sedimentary rocks and metamorphic rocks basalt and granite are two types of igneous rocks.
Basaltic and granitic magma differences. What is the difference between basaltic magma and granitic magma. Granitic magma is basic viscous a high melting. One major difference between basaltic and granitic magma is their specific mineral contents. What are the differences between basaltic and andesitic lava.
Other articles where granitic magma is discussed. 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. Andesitic lava is an example of a high viscosity lava whereas balastic lava has a low. Granitic magma is basic viscous a high melting point with a high percentage of silica.
Basaltic magma is acidic fluid rich in iron and magnesium but poor in silica. Basalt is an extrusive igneous rock whereas granite is an intrusive ingenuous rock. Basalt is volcanic or extrusive forming at the surface while granite is plutonic or intrusive forming beneath the surface. Those who do not know extrusive rocks are those formed of lava coming out of volcanoes whereas rocks formed of magma that has yet not come out of the volcano are termed as intrusive rocks.
First of all you should know the difference between lava and magma magma and lava are both molten liquid rock but magma is moltenrock produced underneath earth surface while it magma erupts on the surface of earth it is called lava. Basaltic magma is acidic fluid rich in iron and magnesium but poor in silica. 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. The key word that should be used when describing different lava types is viscous which essentially means how thick the lava is with a high viscosity describing a very thick slow moving lava.
