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

2nd Flap
C Fault This principle states D B C A D that if one geological B intrusion feature cuts across A another, the feature that has been cut is older. Principle of Crosscutting
Principle of Inclusions Principle of Baked Contacts Principle of Original Horizontality
Principle of Original Continuity

Intrusion http://faculty.icc.edu/easc111lab/labs/labf/igneousintrusion/igneousintrusion.html
8 Relative Dating Foldable.notebook May 02, 2012 Flap 3
This principle states that if an igneous rock intrusion such as a dike contains xenoliths (rock fragments) the rock fragments must be older. C B A .. D intrusion xenolith Principle of Inclusions
Principle of Original Horizontality
Principle of Original Continuity

4th Flap
An igneous rock intrusion "bakes" (metamorphoses) B surrounding rocks. the A C rock that has been baked is older than the intrusion. Principle of Baked Contacts Principle of Original Horizontality Principle of Original Continuity

Principle of Baked Contacts
Orange zone is baked. Lava flow above it.

5th Flap
This principle states that Folding is younger sedimentary rock layers are formed in relatively flat layers. Folding and B tilting of layers occur after the rock layers form. A

Pre Post Learning Target Big Ideas Assess Assess I can apply geologic principles in order to correctly sequence (relative date) rock layers I can do that *I can do that with review ? can't do that
