Basaltic andesitic granitic.

Earth contains three kinds of rocks namely igneous rocks sedimentary rocks and metamorphic rocks basalt and granite are two types of igneous rocks. Basaltic magma is a form of what is called mafic magma meaning it is lower. Appearance of basalt is dull and soft and that of andesite is dull and soft. Other articles where granitic magma is discussed.

The hardness of basalt is 6 and that of andesite is 7. One major difference between basaltic and granitic magma is their specific mineral contents. A quartz b feldspar c olivine. Properties of rock is another aspect for basalt vs andesite.

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. Rank these minerals in order of partial melting. This magma may have received a granitic contribution by melting granitic rocks as it ascended or mixed with granitic magma. Chemical composition felsic granitic intermediate andesitic mafic basaltic ultramafic dominant minerals quartz potassium fodspar sodium rich plagioclase edspar amphibole sodium and calcium rich plagioclase feldspar pyroxene calcium rich plagioclase feldspar olivine pyroxene accessory minerals amph bole muscovito blotte pyroxene biotite amphibole olivine calcium rich plagioclase feldspar.

Basalt is available in black brown light to dark grey colors whereas andesite is available in bluish grey grey pink yellow colors. Andesitic lava is an example of a high viscosity lava whereas balastic lava has a low viscosity so is more runny. Granitic andesitic basaltic ultramafic. Plagioclase feldspar and quartz.

High silica content in the andesitic lava contributes to causing this high viscosity and low silica content in the basaltic lava means it is of a lower viscosity. 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. 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.

Andesite derives its name from the andes mountains of south america. Basaltic granitic and andesitic are the three basic compositional types of magma molten rock beneath earth s surface. A basaltic c andesitic b granitic. All rocks of igneous origin consist of magma or molten earth that finds its way up to.
