PLEASE NOTE:
Cellular phones, iPods, Blackberries, Bluetooth, headphones, computers, pocket calculators, dictionaries, translators or, in general, ANY KIND of electronic device CANNOT be used during the test.
All electronic devices MUST BE TURNED OFF: if a cell phone rings, if a light is visible, or a device is on while in class during test time, you will not be allowed to finish your test and your result will be invalidated.
You cannot use any text, manual, note, dictionary, pocket calculator, flash card, or any other source of information except your brain. You will NOT need a ruler for this test.
You will ONLY need to bring:
- one Scantron, Form 882-E
- a number 2 pencil
- an eraser
This study guide must be interpreted (literally) as a guide to the study of the subject and not as a listing of possible questions.
There is no additional information compared to what has been said, discussed, shown, illustrated in class.
It is YOUR personal responsibility to cover the materials listed below on the lecture textbook, on the lab textbook, on the web pages, and on your notes.
I would strongly recommend that you peruse your notes for completeness of information: some information that has been detailed in class is only mentioned briefly on the textbooks, and you are responsible for covering that; know what the key terms and concepts are (see the list at the end of each chapter on both your textbook and your lab manual); exercise with the questions for review also found at the end of each chapter. Review the materials from your quizzes.
Read the summary at the end of each chapter, try to answer review questions, try to work with other fellow students if you find it useful.
Never hesitate to ask me questions in class or during the lab.

Chapter 7 - Metamorphism and Metamorphic Rocks
- Know the Introduction
- Know Metamorphism
- Know Factors Controlling the Characteristics of Metamorphic Rocks
- know the difference between confining pressure and differential stress
- know what foliation is (and do not confuse foliation with fissility, typical of shale, a clastic sedimentary rock, see Chapter 6)
- review in particular Figure 7.6, page 162)
- Know Classification of Metamorphic Rocks (see also Table 7.1, page 163)
- Know the contact metamorphic rocks: marble, quartzite and hornfels
- Know the regional metamorphic rocks: slate, phyllite, schist, gneiss and migmatite
- Know Types of Metamorphism
- Know Metamorphic Grade
- Know in particular Figure 7.18, page 170
- Know about Plate Tectonics and Metamorphism (see also Figure 7.21, page 173)
- Know Hydrothermal Metamorphism and Plate Tectonics, including Metasomatism and Hydrothermal Rocks and Minerals
- Know about black smokers
- Review in particular Figures 7.23, 7.24, and 7.25, page 175
ALSO:
- Review the summary at the end of the chapter
- Learn the terms to remember
- Answer questions in the "testing your knowledge" section
Chapter 8 - Time and Geology
- Know the Introduction
- Know The Key to the Past
- Know who Nicolaus Steno, James Hutton, Charles Lyell, William Smith, and Charles Darwin were and what was their contribution to geology (an extended guide to this can be found on the web site, on the stratigraphy pages. You do not need to study or know all of this section: just refer to the basic facts concerning the four scientist cited above and discussed during lecture).
- Know Relative Time
Among other things:
- Know the Introduction
- Know the difference between Relative Age and Numerical Age
- Review (from chapter 6) what contacts and Formations are
- Know the three Principles of Steno, and who Steno was
- Know the other two Principles: cross-cutting relationships and inclusions
- Know what Unconformities are, and the three kinds we described (You can skip the term of Paraconformity, but still know it is a possible kind of unconformity). Check out the web site page on unconformities
- Know Correlation, and how we proceed to correlate
- Know in particular the use of Fossils, the Principle of Faunal Succession, what is an Index Fossil, what is a Fossil Assemblage
- Know the Standard Geologic Time Scale:
- know the difference between periods of time and the rocks that represent those periods of time
- know names and relative order of Eons (Eonothems), Eras (Erathems) and Periods (Systems)
- know numerical ages for the Precambrian / Phanerozoic boundary, and for the Paleozoic / Mesozoic and Mesozoic / Cenozoic boundaries. Use Figure 8.24, page 199, for reference.
- Know Numerical Age
Read the whole paragraph, but know in particular:
- about radioactive isotopes (not the single couples parent - daughter but the concept of radioactivity and radioactive decay)
- about parent and daughter isotopes, and the concept of half-life
- be able to calculate numerical ages using simple math, when you know the amounts of P, D and the half-life of an isotope. You are supposed to know the half-life of 14C. If other isotopes will be used, I will provide you with the proper numbers.
- about the differences in dating rocks and in dating organic materials: what do you use, why can you use it, how does it work and what are the orders of magnitude of time involved
- about Uses of Isotopic Dating
- Know Combining Relative and Numerical Ages
- Know Age of the Earth
Be able to use all the concepts you learned so far: for instance, can a Jurassic chert inclusion be found in a Triassic limestone? (answer: NO! Inclusions are always older than the rock that hosts them. The Jurassic Period is younger than Triassic Period, so you can not have a inclusion that is younger than the rock in which it is found).
ALSO:
- Review the summary at the end of the chapter
- Learn the terms to remember
- Answer questions in the "testing your knowledge" section
