  1. Welcome to Medfield (…a seemingly peaceful town)

  2. …but a crime’s been committed!!

  3. REMEMBER… In the Early Paleozoic Era, North America was… • …covered by oceans!!

  4. Throughout the Paleozoic, North America is pushed up and out of the oceans and the continents merge to form the super-continent… PANGAEA!!

  5. The supercontinent begins to break apart and head to our modern-day continental positions in the Age of Reptiles… …the Mesozoic Era!!

  6. So, in the Cenozoic Era, we can expect that the continent of North America, which used to be the ocean floor, would be mostly… …Sedimentary Rock!!!

  7. Galena Sulfide Ore (igneous intrusive) 90/90 Cleavage & Fracture Test Color Hornblende Diorite (igneous intrusive) Streak Test 120/60 Halite 90/90 Cleavage & Fracture Test Greater than 3 Rock Salt (Sedimentary chemical) None/white Calcite Hardness Test Limestone (Sedimentary organic) 120/60 Cleavage & Fracture Test flakes Biotite Pagioclase (Igneous extrusive) Color Streak Test 3 or less Muscovite Muscovite schist (Metamorphic) flakes Cleavage & Fracture Test None/white Gypsum Gypsum (Sedimentary chemical) 180 1 direction

  8. What type of rock is Diorite? IGNEOUS!!!

  9. So, the sedimentary rock must have been… STOLEN!!!

  10. Let’s examine the evidence: Diorite Granite Rhyolite Pink Granite High Elevations 20 miles WIND Glaciers Running Water
