Lecture Notes - Metamorphism Introduction
Lecture Notes - Metamorphism Introduction • Metamorphism is a change of form that includes the growth of new minerals, typically in response to a rise in temperature and normally without the involvement of a magma.
Metamorphism and Metamorphic Rocks
Metamorphism and Metamorphic Rocks Two weeks ago we examined igneous rocks—rocks which were formed from melted material (high temperature). Last week we examined what happens to rocks exposed at the Earth's surface (low temperature, low pressure).
Chapter 4 Metamorphic Rocks
Regional Metamorphism The most widespread and easily recognizable metamorphic rocks are those that form through regional metamorphism. This is a large scale process involving both heat and directed pressure, ...
