  1. Geology of Mercury By Triana Henz

  2. Stratigraphy • Terrian reconnaissance • Images of the planet • Classification of images • Find cause and affect • Chronostratigraphic classification • Finding major events

  3. First Map of Mercury • Trask and Guest were the first to map Mercury once the Mariner 10 images were analyze • There were six things that had caught their eyes the first time they were looking at the images • Other people after them help develop the stratigraphic that is used today for Mercury

  4. Wide-spread inter-crater plains

  5. Heavily cratered plains

  6. Caloris basin and related deposits

  7. Smooth Plains

  8. Hilly and Lineated antipodal to Caloris Basin

  9. Younger craters

  10. Pre-Tolstoj • The oldest identified terrian • Occurred before 4 Gigaannum (Ga) • Multiringed basin deposits • Extensive intercrater plains • High impact rate • Crustial formation and early evolution

  11. Tolstojan System • Tolstoj basin • ~4 - 3.5 Ga • Goya Formation • “Archimedean” craters

  12. Calorian System • Caloris Impact and basin • Wide-spread smooth plains • 3.9 – 3(.5) Ga • Caloris Group

  13. Caloris Montes and Nervo

  14. Odin

  15. Van Eyck Formation

  16. Mansurian System • Mansur crater • Other impact craters with no bright rays • No evidence for regional volcanic or tectonic activities • ~3(.5) – 1 Ga

  17. Kuiperian Period • ~1 Ga to present • Bright-rayed crater Kuiper • Deposits of impact craters with their bright rays still visible

  18. Messenger • Let us see what’s on the “dark side” • The respective data that is collected will help place together the global geologic sequence together • The data will help piece together the history of Mercury
