Geologic Principles Foldable

• You will need 3 pieces of paper to make your foldable.• Stagger the papers out so that you have a 1­inch tab for each different color.• Hold the 3 papers together staggered and fold in half• Staple the papers along the binding

This principle states that if an igneous rock intrusion such as a dike contains xenoliths (rock fragments) the rock fragments must be older.
