Presentation Transcript

  1. Geology of Texas Caverns • By: Heather Hatton • SCI/245

  2. Texas Caves

  3. Geological Features & Events • Solution caves • Dissolution • Erosion • Gravitational breakdown • Limestone breaks down • Zone of saturation • Karst • Sinkholes • Caves • Underground drainage systems

  4. Geological Feature • Limestone • Sedimentary rock • Calcium carbonate • Accumulated deposition/fossilization • Calcareous remains • Marine organisms • Freshwater organisms • Formations • Flowstones, stalactites, stalagmites, helictites, soda straws and columns

  5. Geologic Time • Under dispute • Creationists vs. scientists • Sulfuric acid vs. carbon acid

  6. Geological Event • Speleogenesis • chemical processes, erosion from water, tectonic forces, microorganisms, preasure, atmospheric influences, and digging • In Texas • No active plate tectonics • No active or document volcanoes • Few earthquakes

  7. Weathering and Erosion • Reactions to limestone • Water, Gases, and Acidic solutions • Sulfuric acid • Dissolution • Karst topography • Caves/Caverns, Sinkholes, Disappearing stream, and Springs

  8. Igneous Rocks • No igneous rocks • Sedimentary rocks Sedimentary Igneous

  9. Sedimentary Rocks • Discuss the relation of sedimentary rocks to your region. • Rocks formed on surface of the earth, land or water • Created by accumulation of layers of sediment • Cemented together by minerals or chemicals • Fossils are found in these rocks

  10. Metamorphic Rocks • Discuss the relation of metamorphic rocks to your region. • Rocks formed deep in earth • Not melted, composed into denser rocks

  11. Water, Desert, and Glaciers • Groundwater • Sulfuric acid produced • No deserts or glaciers directly involved

  12. Resources • Limestone • Aquifers

  13. Conclusion • Formation of caves • Limestone • Sedimentary rocks • History of land formations
