Describe the environmental changes that cause metamorphism, including changes in temperature, confining (burial) pressure, directed stress and hydrothermal fluids
Describe the environmental changes that cause metamorphism, including changes in temperature, confining (burial) pressure, directed stress and hydrothermal fluids Recognize that metamorphic changes occur in the solid state; melting is an igneous process. Know the types of alterations that rocks undergo via metamorphism: changes in mineral structure, change in mineral/clast shape due to plastic deformation […]
