Basaltic Andesitic Granitic

Other articles where granitic magma is discussed.

Basaltic andesitic granitic. All rocks of igneous origin consist of magma or molten earth that finds its way up to. Basaltic granitic and andesitic are the three basic compositional types of magma molten rock beneath earth s surface. This magma may have received a granitic contribution by melting granitic rocks as it ascended or mixed with granitic magma. Andesitic lava is an example of a high viscosity lava whereas balastic lava has a low viscosity so is more runny.

This is because their parent magmas formed from the partial melting of a basaltic oceanic plate. D pyroxene a quartz b feldspar. Rank the magma types in order of increasing low to high silica content a basaltic b granitic c andesitic. Both lavas are formed at different plate boundaries which is why.

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. Earth contains three kinds of rocks namely igneous rocks sedimentary rocks and metamorphic rocks basalt and granite are two types of igneous rocks. Rank these minerals in order of partial melting. Andesite derives its name from the andes mountains of south america.

Which of the choices below lists the four basic compositional groups of igneous rocks ranging from the highest silica content to the lowest silica content. Appearance of basalt is dull and soft and that of andesite is dull and soft. Plagioclase feldspar and quartz.

Basaltic magma is a form of what is called mafic magma meaning it is lower. A quartz b feldspar c olivine. 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. A basaltic c andesitic b granitic.

One major difference between basaltic and granitic magma is their specific mineral contents. 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. The hardness of basalt is 6 and that of andesite is 7. Basalt is available in black brown light to dark grey colors whereas andesite is available in bluish grey grey pink yellow colors.
