Metamorphic rocks form when other pre-existing rocks change under extreme heat or pressure. Depending on the environment of their formation, they may be foliated or non-foliated. Most metamorphic rocks are classified based on whether or not they display foliation.
In this lab, you will have the chance to see some metamorphic rocks, to identify their texture, and to assign a name to them. You will need to download the blank data sheet to enter your lab observations.
