Is Granite Made From Basaltic Magma

Basalt and granite are both made from the same magma.

Is granite made from basaltic magma.

It mainly occurs on the floor of the ocean as magma solidifies quickly coming in contact with cool ocean water. 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. It is thought that large amounts of basaltic magma can be plastered to the bottom of a continent in a process called underplating.

The mantle rocks located at depths from about 70 to 200 kilometres are believed to exist at temperatures slightly above their melting point and. Basalt forms when magma cools and solidifies on the surface of the earth. Granite that contains the same mineral assemblage as basalt is known as gabbro. Basalt is more common in oceanic crust while granite is more common in continental crust.

Peridotitic magma ultramafic coarse grained has very high levels of iron and magnesium. Other articles where basaltic magma is discussed. Granite is formed when magma cools slowly. Which is an example of an extrusive.

Is an intermediate between basaltic magma and granitic magma high gas content. 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. 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. On the other hand granite occurs above the ocean and makes up much of continental crust.

Granite is a an you may use your rock charts intrusive igneous rock. 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. How magma melts geologists call the whole process of making melts magmagenesis. Granite peridotite basalt obsidian and all the rest.

Basically it is basalt that has cooled deep underground allowing it to form granitic textures. Granite forms when magma rich in silica sodium and potassium cools slowly deep underground. How can magma turn into granite. Summary of basalt vs.

It forms from lava flows which extrude onto the surface and cool.
