Metamorphism does occur when rocks come in contact with magma but it is very localised. It is contact metamorphism and a close look with a hand lens will normally show a change to the rock, sometimes only millimetres wide.
Contact metamorphism occurs next to an intrusion of molten magma. This type of metamorphism happens when hot magma comes into contact with existing rock, causing the rock to undergo changes in mineralogy and texture due to the heat and pressure.
Two types of metamorphism occur in earth's crust. One is when small volumes of rock come in contact with magma. And the other is when large amounts of the earth's crust are effected by heat and pressure
Metamorphism actually occurs when rocks are subjected to high temperatures and pressures deep within the Earth's crust. This can happen due to tectonic forces, such as during the formation of mountain ranges, or when rocks are buried deep in the crust. While magma can be involved in some types of metamorphism, it does not necessarily have to be present for metamorphism to occur.
Convergent plate boundary, because it is associated with plutonism. It is the result of the temperature increase from the intrusion into the surrounding country rock.

Metamorphism can occur through contact metamorphism, where rocks are altered by heat from nearby magma; regional metamorphism, where rocks are subjected to high pressure and temperature over a large area; burial metamorphism, where rocks are subjected to increased pressure from being buried deep underground; and dynamic metamorphism, where rocks are deformed under high pressure but low temperature conditions along faults or shear zones.

Contact metamorphism is least likely to occur at locations where there is little to no intrusion of magma near the Earth's surface. In areas with minimal igneous activity and no heat source to drive the metamorphic changes, contact metamorphism is less likely to take place. Generally, regions located far away from tectonic plate boundaries or volcanic hotspots are less prone to experiencing contact metamorphism.

Dynamic contact metamorphism occurs along tectonic plate boundaries where rocks come into contact with hot magma intrusions, while regional metamorphism occurs over large areas along convergent plate boundaries where high pressure and temperature conditions alter rocks deep within the Earth's crust.
Contact metamorphism occurs typically around intrusive igneous rocks as a result of the temperature increase caused by the intrusion of magma into cooler country rock. The area surrounding the intrusion where the contact metamorphism effects are present is called the metamorphic aureole. Contact metamorphic rocks are usually known ashornfels. Rocks formed by contact metamorphism may not present signs of strong deformation and are often fine-grained.
When rocks stack on each other, contact metamorphism can occur. This type of metamorphism happens when the high temperature and pressure from nearby molten rock alter the composition of the rocks in contact.

Yes, metamorphism can occur without deformation. Contact metamorphism, which results from high temperatures and pressures near igneous intrusions, can happen without significant deformation of the rock. Additionally, burial metamorphism can occur due to increased pressure from overlying rocks without accompanying deformation.
Contact metamorphism occurs when rocks come into contact with high-temperature magma. Minerals formed under these conditions are typically found near igneous intrusions or volcanic activity, where the heat source is present. This can occur in areas such as volcanic regions, magmatic arc settings, or near igneous rock formations.
