By Magma I'm guessing you mean the molten sedimentary rocks. The process is called metamorphism.
The process through which single parent magma can form rocks with different compositions is known as fractional crystallization. It occurs as the magma cools and solidifies, with different minerals crystallizing at different temperatures. As these minerals crystallize and settle out of the magma, they can form different rock compositions depending on the minerals that have formed. This process can produce a range of rock compositions from a single parent magma.
Igneous rocks are formed by cooling magma.
Magma contains rocks which are not suitable for making extrusive rocks. Magma is only inside the chamber of a volcano, and comes out as lava. There is 98.3% Magma will be made into extrusive rocks.
Magma
The transition form magma to rock is a process of cooling.
Intrusive Igneous rocks
Regional Metamorphism
By Magma I'm guessing you mean the molten sedimentary rocks. The process is called metamorphism.
A rock cycle starts off as magma. Then as the magma cools, crystals form, and eventually the magma solidify into igneous rocks. The process breaks down into sedimentary rocks. The processes change a pre-existing igneous or sedimentary rock into a new rock called metamorphic rocks, then it melts into magma and the process starts all over.
A process that alters rocks as a result of heat generated from magma
Rocks are formed when magma cools.
The process through which single parent magma can form rocks with different compositions is known as fractional crystallization. It occurs as the magma cools and solidifies, with different minerals crystallizing at different temperatures. As these minerals crystallize and settle out of the magma, they can form different rock compositions depending on the minerals that have formed.

Rocks formed from magma are igneous rocks. Extrusive igneous rocks form from lava at or near the surface. Intrusive rocks form from magma below the surface.
