  1. Virginia Geology The Five Physiographic Provinces of Virginia

  2. The Five Provinces

  3. Virginia is divided into 5 provinces based on their geologic formations.

  4. After looking at the first few slides, how many of the provinces can you name? Do you know in which province we live?

  5. Be sure to take good notes! There will be a quiz at the end of this presentation.

  6. 1. Coastal Plain

  7. The Coastal Plain runs from the fall line on the west, to the Atlantic Ocean on the east • It is a terraced landscape

  8. Sand, silt and clay produced by erosion of the Appalachian Mts. covers the plain • As sea levels rose and fell, fossils were left at various layers

  9. Virginia Fossils • Fossils include various marine organisms like clams, scallops, sharks teeth, and other hard remains

  10. Virginia Fossils • Paleozoic, Mesozoic, and Cenozoic fossils are found in Virginia

  11. 2. Piedmont

  12. Facts about the Va. Piedmont • It is an area of rolling hills underlain by ancient igneous and metamorphic rock • It is the largest of the provinces

  13. Mining the Piedmont • High quality slate is mined from this area • The Piedmont host one of the worlds largest kyanite mines ( see picture of kyanite )

  14. 3. Blue Ridge Mountains

  15. Blue Ridge Facts • The billion year old igneous and metamorphic rocks are the oldest in the state

  16. Blue Ridge Facts • It is a high ridge separating the piedmont from the valley and ridge province

  17. Ready for a quick review? • 1. Which province, that has already been described, is known for having layers of fossils?

  18. Quick Review • 2. Which province is the largest? • 3. Which province has the oldest rocks? • 4. Which province has slate and kyanite mines?

  19. Let’s see how you did! • 1. Coastal Plain • 2. Piedmont • 3. Blue Ridge • 4. Piedmont

  20. 4. Valley and Ridge Province

  21. Valley and Ridge • The Valley and Ridge Province is an area of long parallel ridges and valleys underlain by ancient folded and faulted sedimentary rocks

  22. Cambrian fossil algal structures are found in the V&R Province

  23. Limestone outcrops are common in the Valley and Ridge Province

  24. This area is also famous for Karst • What does karst mean? • Want some hints?

  25. Sink holes!

  26. Caverns!

  27. Think you figured it out? • Karst is an irregular limestone region with sinks, underground streams, and caverns • The Valley and Ridge Province is famous for its caverns, can you name one?

  28. 5. Appalachian Plateau

  29. Appalachian Plateau Facts • The Appalachian Plateau has rugged, irregular topography and is underlain by ancient, flat-lying sedimentary rocks

  30. Appalachian Plateau Facts • Do you notice any thing in these layers?

  31. COAL!

  32. Virginia Coal • Most of Virginia's coal is found in the Appalachian Plateau.

  33. Virginia Coal • These old sedimentary rocks contain many fossils and tons of coal.

  34. Quiz Time • Let’s see how you do on this 10 question quiz. • Ready? Here we go!

  35. Questions! • 1.Which province is covered by sand, silt and clay? • 2.Which province has Cambrian algal fossils? • 3. This province has a terraced landscape.
