Relative Dating Techniques 1 Stratigraphic Record i principle

• Relative Dating Techniques 1. Stratigraphic Record i. principle of original horizontality ii. principle of superposition

• Relative Dating Techniques 1. Stratigraphic Record iii. Law of Lateral Continuity iv. Law of Inclusions v. Cross-cutting relations

• Relative Dating Techniques 1. Stratigraphic Record v. unconformities (1) disconformity: erosion removes a part of otherwise undisturbed rock (2) angular unconformity: rocks below are at an angle in relation to those above (3) nonconformity: sedimentary rocks lie on top of igneous rocks

2. Determining absolute time i. radiometric dating (2) half-life
