I. Parent Rocks

Rocks that have been changed from an original “parent”

rock

II. How are Metamorphic Rocks Formed?

Formed under tremendous heat, great pressure, and chemical reactions

Can make new minerals Most are found on or near plate

boundariesMetamorphism is changing one type of

rock into another as a result of heat(from mantle), Pressure (from layers above) and/or chemical reactions.

III. Where does the Heat Come From?

The heat comes from: 1. Mantle2. Pressure of the

layers3. Movement of

the Plates on Earth

Earth’s Plates

IV. What does Metamorphism change?

Metamorphic rocks can change:

1. a rocks appearance, texture

2. crystal structure3. mineral content It can form from a/an: 1. Igneous2. Sedimentary3. Another

metamorphic rock!

a. Foliated – mineral crystals are arranged in parallel layers or bands

Examples: Schist, slate, and gneiss

b. Nonfoliated – rocks are not banded and do not break into layers Examples: Marble and quartizite

V. Types of Metamorphic Rocks

Foliated

Non-foliated

NON-Foliated

VI. Contact vs. Regional Metamorphism

Used in construction of buildings

and walkways

Used in tables, floors, and

roofing
