GEOL 111 Learning Assignment 6 Metamorphism 1. Define contact metamorphism, regional metamorphism, and dynamic metamorphism Type of Metamorphis m Definition Contact Changes in rock caused by the heat from a nearby magma body. Regional Metamorphism associated with large-scale mountain building. Dynamic The process of metamorphism alteration of rocks through heat, pressure, and mineral exchange that occurs in response to tectonic forces and deformation within the Earth's crust . 2. Metamorphic rocks come from pre-existing rocks (aka parent rocks) that are formed due to increased heat, pressure, and hydrothermal fluids. The intensity of the metamorphism determines the metamorphic rock formed. Use the provided Grade table to help fill in the table below. Please note: zones and grades may overlap. Use your textbook to determine the foliation, (F=foliated, NF=Nonfoliated).
