Geology Geology Presentation Transcript

  • Field/Lab Assignment ll
    • By: Jaime Padilla
  • Faults
  • Faults
    • This picture was taken by Coalinga.
    • This Fault is known as a Gouge fault because the two layers are separated by a gray layer that looks very ground up.
    • consists of broken up and smashed pieces of rock which forms as the two sides of the fault moving against one another.
  • Weathering process mechanical/physical
  • Weathering Process-Mechanical
    • Mechanical weathering takes place when rocks are broken down without any change in the chemical nature of the rocks.
    • Exfoliation is the process where the rocks break in sheets along the joints that they have parallel to the earth surface.
    • The forces that break rocks down can be numerous, and include such things as pent up energy as the Earth’s crust slowly moves.
  • Weathering Process-Physical
    • Physical weathering is the class of processes that causes the disintegration of rocks without chemical change.
    • The best example I have seen for physical weathering is sedimentary rocks because you can the dirt brush of the rocks.
    • This process takes thousands of years, but it’s a process that has been within the Earth longer than humans.
  • Mass Wasting
  • Mass wasting
    • This picture was taken in Cambria beach way out in the shore.
    • Mass Wasting occurs when the downslope movement of rock and soil pulls down because of gravity.
    • As you can also see erosion is also taken place.
  • sedimentary environments continental, marine, and transitional
  • Sedimentary Environments
    • Continental is dominated by erosion and deposition associated with streams, glacial, and wind.
    • Marine is shallow, deep of continental layers
    • Transitional is off the shoreline and consist of tidal flats, lagoons, and deltas.
  • iphone 3G geological field tool
    • This electronic device is considered as a geological field because it contains GPS.
    • It incorporates accelerometers which can be used to measure the tilt of the device.
    • Test over geological structures, the relative speed and accuracy of a conventional compass clinometers and the iphone compass hybrid are demonstrated and campared.
  • iphone 3G geological field tool
    • iphone’s compass is as accurate as the Brunton compass.
    • It has different amount of apps so you can use them for different situations
    • For example: The ihandy Carpenter app in the premium version serves well as a level and plumb line, making it work for measuring dip angles.
