1 Geology 3620 Exam 3 Team Questions (1) Some submitted questions have been modified or not used. Refer to question guidelines to search for answers, several are in your textbook. (2) Expect additional questions from me on the exam. These will come mainly from Tectonics and Sedimentation (Section 19) and I will still include some from sections 17 to 19. 1. Seismic reflections were used to develop Vail Curves which are used for: A. Identifying structural traps for oil and gas B. Identifying shifts in the magnetic polarity of the Earth C. Interpreting fluctuations in sea level throughout geologic time D. Interpreting the lateral extent of prehistoric debris flows 2. Which maps are used to identify three-dimensional subsurface characteristics? A. Facies maps B. Structure contour maps C. Isolith maps D. Isopach maps 3.What is the oldest and one of the most reliable dating techniques? 10. You have been hired by Crystal-Clear Consulting to assess a potential windmill farm. Your supervisor asks you to conduct an SP test of the development area. For your first sample, you get a reading that is near positive. Using your knowledge from this Stratigraphy and Sedimentation class, you suspect that this is a(n): 11. Which of the following variables does not affect sequence stratigraphy? Tectonic subsidence creates the home for sediments to be deposited B. Sediment supply affects the volume of sediment or how much of a basin is filled C. Eustatic change in sea level controls rates of diagenesis D. Climate controls types of sediments deposited 12. Which type of map shows the units outcropping at an unconformity surface? 13. How does decreasing pore space affect resistivity? A. As pore size decreases resistivity decreases B. As pore size decreases resistivity increases C. Resistivity logs can’t be used if pore spaces are present D. Pore spacing doesn’t affect resistivity 14. As a young graduate from S&T, the only true dating scene for you is the radioactive dating of uranium in outcrops to determine the geologic age of their formation. You recall that the half-life for Uranium-238 to fully decay into Lead-206 is 4.46 billion years before heading to an impressive zircon-rich rhyolite outcrop discovered by the successful geologic research and consulting firm that you work for- Limbaugh Doster Inc. A client is wondering just how old the outcrop is, and it’s up to you to figure it out! After carefully analyzing the material, you’ve found that the uranium in the outcrop has undergone one-half life of decay thus far. Therefore, you can deduce that the age of this wonderous outcrop is approximately:

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
