Is Granite Made From Basaltic Magma

Granite that contains the same mineral assemblage as basalt is known as gabbro.

Is granite made from basaltic magma.

How can magma turn into granite. Granite is a an you may use your rock charts intrusive igneous rock. Granite forms when magma rich in silica sodium and potassium cools slowly deep underground. 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 volcanic activity.

Basalt and granite are both made from the same magma. Summary of basalt vs. Granite is formed when magma cools slowly. How magma melts geologists call the whole process of making melts magmagenesis.

Other articles where basaltic magma is discussed. Peridotitic magma ultramafic coarse grained has very high levels of iron and magnesium. Which is an example of an extrusive. It is thought that large amounts of basaltic magma can be plastered to the bottom of a continent in a process called underplating.

Although basaltic magma can result in basaltic rocks and granitic magma can result in granitic rocks they can also form other rocks depending on how quickly the magma cools. With the slow release of heat and fluids from that basalt a large amount of continental crust could turn to granite at the same time. Basaltic magmas that form the oceanic crust of earth are generated in the asthenosphere at a depth of about 70 kilometres. Basalt forms when magma cools and solidifies on the surface of the earth.

Other articles where granitic magma is discussed. It mainly occurs on the floor of the ocean as magma solidifies quickly coming in contact with cool ocean water. We know it exists because every igneous rock type solidified from a molten state. Granite peridotite basalt obsidian and all the rest.

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. Is an intermediate between basaltic magma and granitic magma high gas content. The mantle rocks located at depths from about 70 to 200 kilometres are believed to exist at temperatures slightly above their melting point and. Basically it is basalt that has cooled deep underground allowing it to form granitic textures.

On the other hand granite occurs above the ocean and makes up much of continental crust.
