1. METAMORPHIC ROCKS

2. Metamorphic Rocks:
Formed due to intense heat and pressure deep inside the earth.
May have ribbon-like layers or may have shiny crystals.
Classified into 2 categories:
Foliated
Nonfoliated

3. Foliated Metamorpic Rocks:
The mineral grains are arranged in bands or layers
Examples:
Gneiss
Slate

4. GNEISS
SLATE

5. Nonfoliated Metamorphic Rocks
Mineral grains are NOT aligned
Examples:
Marble
Quartzite

6. MARBLE
QUARTZITE
