Contact metamorphism can occur in this scenario.
When metamorphism occurs due to heat generated by magma, it is called "contact metamorphism." This process typically happens when surrounding rocks are heated by the proximity of molten magma, leading to changes in mineral composition and texture. The effects are usually localized around the intrusion of magma, resulting in the formation of metamorphic rocks such as hornfels.

It is called contact metamorphism.
When magma cuts across another rock and hardens, the resulting formation is called an "intrusion" or "igneous intrusion." This occurs when molten rock, or magma, forces its way into pre-existing rock layers and solidifies, typically forming structures such as dikes or sills. Intrusions are important in understanding geological processes and the history of the Earth’s crust.
Contact metamorphism is most likely to change shale to hornfels. This process occurs when rocks are subjected to high temperatures and pressures due to contact with a magma intrusion, leading to the recrystallization of minerals in the original rock. Hornfels is typically formed under these conditions and is characterized by a fine-grained, non-foliated texture.

An intrusion of basaltic magma would likely cause greater contact metamorphism compared to an intrusion of rhyolitic magma. Basaltic magma has higher temperatures and higher fluidity, allowing it to heat surrounding rocks more effectively and induce more intense metamorphic changes.

Contact metamorphism is what occurs because of close proximity to a mass of magma.
It is called contact metamorphism.
Contact metamorphism is the process of forming rocks from the heat of magma intrusion. Regional metamorphism, meanwhile, is the process of forming rocks by pressure and heat at plate boundaries.
It is called contact metamorphism.
Regional metamorphism occurs over a large area and at high pressures and temperatures, typically associated with tectonic processes like mountain building. Local metamorphism, on the other hand, is confined to a small area and occurs at lower pressures and temperatures, often as a result of contact with a heat source like a magma intrusion.
Magma intrusion refers to when molten rock (magma) forces its way into existing rock formations beneath the Earth's surface. This intrusion can create new igneous rock formations, as well as potentially lead to volcanic activity if the magma reaches the surface.
When rocks come in contact with molten rocks from an igneous intrusion, the surrounding rocks may undergo contact metamorphism, where their mineralogy and texture are altered due to the heat and chemical reactions with the intruding magma. This can result in the formation of new minerals and textures in the rocks near the intrusion boundary.
