Basaltic Magma And Granitic Magma

Note that solids even though they appear solid have a viscosity but it very.
Basaltic magma and granitic magma. Discuss earthquake mechanisms at the three types of tectonic plate boundaries. Compare and contrast shield volcanoes cinder cone volcanoes and composite volcanoes. Granitic magma is basic viscous a high melting point with a high percentage of silica. Thus basaltic magmas tend to be fairly fluid low viscosity but their viscosity is still 10 000 to 100 0000 times more viscous than water.
Granitic magma is basic viscous a high melting point with a high percentage of silica. Other articles where granitic magma is discussed. Describe the similarities and differences between the andes and the. Granite is formed by the slow cooling of magma within the surface of the earth while basalt is formed when magma quickly cools after breaching the earth s surface through.
Explain why basaltic and granitic magma behave differently as they rise toward earth s surface. The viscosity of basaltic and granitic magma is largely distin guished. Rhyolitic magmas tend to have even higher viscosity ranging between 1 million and 100 million times more viscous than water. The parental granitic magma underwent the mixing of mantle derived mafic magma and crustal felsic magma coupled with fractional crystallization during magma ascent before emplacement.
Basaltic magma is acidic fluid rich in iron and magnesium but poor in silica. Magmas are with viscosity of 10 4 5 pa s scaillet et al 1998. For example h 2 o rich crystal poor and high silica. Step 1 of 4.
Magma is a fluid of high temperatures or semi fluid with rock fragments formed within the earth s crust. Fs show all show all steps. Andesitic magma is. Although granitic magmas can be formed through magmatic differentiation of andesitic magmas most granitic magmas probably form when hot basaltic magma ponds becomes trapped because of its greater density below continental crust figure 2.
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.
