Is Granite Made From Basaltic Magma

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.

Is granite made from basaltic magma.

It is thought that large amounts of basaltic magma can be plastered to the bottom of a continent in a process called underplating. Granite that contains the same mineral assemblage as basalt is known as gabbro. Basalt is an igneous volcanic rock that forms commonly in oceanic crust and parts of continental crust. Basalt forms when magma cools and solidifies on the surface of the earth.

It mainly occurs on the floor of the ocean as magma solidifies quickly coming in contact with cool ocean water. Granite is a an you may use your rock charts intrusive igneous rock. Which is an example of an extrusive. On the other hand granite occurs above the ocean and makes up much of continental crust.

Granite is formed when magma cools slowly. 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. Granite peridotite basalt obsidian and all the rest. How can magma turn into granite.

Summary of basalt vs. Other articles where granitic magma is discussed. Granite forms when magma rich in silica sodium and potassium cools slowly deep underground. It forms from lava flows which extrude onto the surface and cool.

Peridotitic magma ultramafic coarse grained has very high levels of iron and magnesium. Basically it is basalt that has cooled deep underground allowing it to form granitic textures. 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. Basaltic magmas that form the oceanic crust of earth are generated in the asthenosphere at a depth of about 70 kilometres.

We know it exists because every igneous rock type solidified from a molten state. Basalt and granite are both made from the same magma. Other articles where basaltic magma is discussed. The mantle rocks located at depths from about 70 to 200 kilometres are believed to exist at temperatures slightly above their melting point and.

How magma melts geologists call the whole process of making melts magmagenesis.
