Presentation transcript:

Observations Among the silicate planets, Plate Tectonics is only found on Earth, indicating that special circumstances are required. Plate Tectonics (kinematic description) = Subduction Tectonics (dynamic description); PT = ST Subduction requires dense (= cold & thick) lithosphere to sink beneath less-dense asthenosphere. 1) becomes: When did Earth cool off sufficiently to allow ST to begin? Use geologic evidence to constrain ST start “Smoking guns” of ST: Ophiolites, Blueschists, and Ultra-High Pressure (UHP) terranes Abundance of Ophiolites and first appearance of Blueschists and UHP terranes indicate ST/PT began in Neoproterozoic time (~1000-544 Ma). Start of ST/PT affected global climate: Neoproterozoic Snowball Earth
