Final answer:

Both magmatic fluids and pore fluids of the country rock can have an effect on contact metamorphism.

Step-by-step explanation:

No, the statement is false. Both magmatic fluids and pore fluids of the country rock can have an effect on contact metamorphism. Contact metamorphism occurs when rocks come into contact with hot magmas, causing changes in their mineral content and texture.

The heat from the magmas can cause recrystallization of minerals in the surrounding rocks, while the chemically reactive fluids released from the magma can alter the composition of the rocks. Therefore, both magmatic fluids and pore fluids can play a role in contact metamorphism.
