Magmatic differentiation is the process by which a single magma evolves into different types of rocks through the separation of minerals as it cools and crystallizes. This process can occur through various mechanisms, including fractional crystallization, in which certain minerals crystallize and settle out of the magma, altering its composition. Additionally, processes like assimilation and magma mixing can further modify the chemical characteristics of the magma. Ultimately, magmatic differentiation leads to the formation of diverse igneous rock types from a common magma source.
As a magma crystallizes it undergoes fractional crystallization in which mafic minerals crystallize first and felsic minerals crystallize last. Therefore, as fractional crystallization occurs the magma becomes increasingly less mafic and increasingly more felsic. The viscosity also increases as a magma becomes more felsic.
differentiation.
No, magmatic processes involve the movement and cooling of molten rock beneath the Earth's surface, while metamorphism involves changes in mineral composition, texture, or structure of rocks due to high pressures and temperatures. Magmatic processes can lead to the formation of igneous rocks, whereas metamorphism produces metamorphic rocks.
Magmatic (lava) cooling.
It is felsic, containing rhyolite and high quantities of silicon.
Magmatic differentiation accounts for a variety of igneous rocks occurring in the same body of rock by:Mixing of magmas from two or more sources.Distinct melting events from a variety of sources.Crystal fractionationPartial melting from the same source.Immiscibility.Assimilation of crustal rock by magma.
The intrusive granites which contain ores are the product of solidified magmas, most probably ones that have undergone significant magmatic differentiation.
A magmatic earthquake is an earthquake triggered by the movement of magma, underground molten rock.
No, Magmatic is and adjective meaning of or realting to magma. Magma is not a mineral but molten rock underground.

differentiation.
I am guessing you are talking with regard to magmatic differentiation during the eruption process? If so assimilation is simply the chemical change in the magma due to the magma melting other rock types that make up the walls of the conduit. This process often explains "abnormal" mineral compositions.
What role is played by energy in its various forms to create magmatic and metamorphic rocks?

Because I am imbued with magmatic foresight.
