The lithosphere primarily comprises of volcanic rocks and sediments that contain fluids and water. These fluids contact the rocks surrounding as the lithosphere moves into the mantle in the downward direction. The rock's melting temperature decreases when the fluid begins the enter the hot rock. This melts it to form magma.
Hot fluids migrating into and out of a rock during metamorphism can change the rock's mineral composition, texture, and overall structure. This process, known as metasomatism, allows for the introduction of new minerals and the alteration of existing ones, leading to significant changes in the rock's properties. Additionally, these fluids can enhance chemical reactions and facilitate the recrystallization of minerals, further transforming the rock.
Metamorphic rock forms when existing rock is subjected to intense heat, pressure, or chemically active fluids, causing it to recrystallize and form new minerals. This process can transform existing rock types like sedimentary or igneous rocks into metamorphic rocks like marble, slate, or schist.
One reason a very hot rock might not melt is if it is composed of minerals with high melting points, such as quartz or feldspar. These minerals can withstand high temperatures before reaching their melting point, allowing the rock to remain solid even at extreme heat.

Magma and hydrothermal fluids are hot fluids that can move through small cracks in rock. Magma is molten rock beneath the Earth's surface, while hydrothermal fluids are water heated by volcanic activity that can carry minerals and gases. Both can contribute to the formation of igneous rocks and mineral deposits.
During metamorphism, the minerals present in the rock can recrystallize, change in size, or reorganize their structure due to the influence of the hot fluids. The chemical composition of the rock may also change as elements are exchanged between the rock and the fluids. Overall, these processes can lead to the formation of new minerals and textures in the rock.
When the fluids enter the already hot mantle rock, the melting temperature of the hot rock decreases. As a result, the rock begins to melt.

It becomes a metamorphic rock, altered by heat, pressure, or hot fluids.
Heat, pressure, and hot watery fluids can transform solid rock into metamorphic rock through a process called metamorphism. This process alters the mineral composition and texture of the original rock, known as the parent rock or protolith. Common examples of metamorphic rocks include schist, gneiss, and marble, which originate from shale, granite, and limestone, respectively.
