Themes of the Day:

• The Occurrence of Sedimentary Rocks

Types of Sedimentary Rocks

• Geologic Processes and the Rock Cycle
• Sediments formed by Weathering Processes (Mechanical, Chemical)
• Clastic Sedimentary Rocks - grain size related to depositional energy
  • Conglomerates/Sedimentary Breccia
  • Sandstones - Quartz Arenites, Arkoses, Wackes
  • Mudstones/Shales - clay minerals
• Carbonate Rocks - Limestone, Dolostone
• Evaporites
• Phosphates, BIFs, etc.

Depositional Basins

• Preservation Potential - with age, by tectonic setting
• Sea Level fluctuations
• US Latitude through Time
• Tectonic Settings of Deposition
• Classification of Sedimentary Basins - See Table 11-3, 11-4
• Basin Examples
  • Bay of Bengal
  • Atlantic Rift Basins
  • Eastern US Rift Basins
  • Accretionary Wedge
  • Subduction Zone Cross Section
  • Aleutian Arc - Intraarc Basins
  • Backarc Basins
  • Appalachian Clastic Wedge
  • Central US Basins
