When heat and pressure due to magma intrusions may result in?

When heat and pressure from magma intrusions occur, they can lead to metamorphism of surrounding rocks, altering their mineral composition and structure. This process can create new rock types, such as schist or gneiss, depending on the intensity of the heat and pressure. Additionally, the intrusion can also cause fracturing and faulting in the crust, potentially leading to volcanic activity or the formation of mineral deposits. Overall, these geological processes significantly reshape the Earth's crust.
