No, the rocks formed during metamorphism do not depend on Earth's magnetic field. Metamorphism is the process where existing rocks are altered by high pressure and temperature without being melted. The formation of metamorphic rocks is primarily influenced by the chemical composition of the original rock and the conditions present during metamorphism, such as pressure and temperature.
