  • 1. An LSU Museum of Natural Science presentation to accompany the activity Louisiana Rocks andLouisiana Rocks and MineralsMinerals
  • 2. Objective: Students will gain an understanding of where minerals come from and the environmental impact of mining. Materials For teacher: Stop watch, scale, bucket of pennies For student: 4 chocolate cookies, toothpicks, pencil, data recording sheet, small weigh boat Mining for MMM…Mining for MMM… MineralsMinerals
  • 3. Investigating the layer- cake earth What is stratigraphy? Study of sediment layers and the relationship between rocks and fossils with time.
  • 4. Rules of StratigraphyRules of Stratigraphy • Steno’s Principle of Superposition Lower layers are older than higher layers • Original Horizontality Layers are deposited in (near-) horizontal manner • Principle of Lateral continuity Layers extend laterally in all direction • Cross-Cutting Relationships Layers intruded by other rocks are older than the intruding rocks
  • 5. Unconformities- represents a gap in deposition – lost time! • Nonconformity • Angular • Disconformity Sediment layers are LostSediment layers are Lost…..….. http://epod.usra.edu/archive/images/uncoformitysm.jpg
  • 6. ……..And Moved..And Moved Faults - Surfaces where rocks have fractured and been displaced (move relative to one another).
  • 7. Rules apply across Space and Time!Rules apply across Space and Time!
  • 8. Given the diagram, list the order (oldest to youngest) in which the following events happened: A. Faulting B. Tilting E. Intrusion C. Erosion D. Deposition Classroom assessment activity Deposition 1 Deposition 1 Tilting Tilting Deposition 2 Deposition 2 Intrusion Erosion Faulting 1. Deposition 1 2. Tilting 3. Erosion 4. Deposition 2 5. Intrusion 6. Faulting
  • 9. Illustration of example cake set-up. Note different cake layers (different colors) and fault.
  • 10. Illustration of example cake set-up. Note different cake layers (different colors) and fault.
