General InformationLast Updated  •  September 24, 2012   
PLEASE NOTE:
  • Only students who are enrolled in the class can take the test. If you are not enrolled, for any reason (and in particular, if you have been given an add code and have not used it yet) YOU CAN NOT TAKE THE TEST.

  • You CAN NOT USE cellular phones, iPods, Blackberries, Bluetooth, headphones, computers, pocket calculators, translators or, in general, ANY KIND of electronic device during the test.
    All electronic devices MUST BE TURNED OFF: if a cell phone rings, or if a device is on during test time, you will not be allowed to finish your test and your result will be invalidated.

  • You can not use any text, notes, dictionary, pocket calculator, flash card, or any other source of information than your brain.

  • You will NOT need a ruler or a blue book for this test.

  • You will ONLY need to bring:
    1. one Scantron, Form 882-E
    2. a number 2 pencil
    3. 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.

  • On this study guide, there is no additional or extra information compared to what has been said, discussed, shown, illustrated in class.

  • It is YOUR personal responsability to cover the materials listed below on the lecture textbook, on the lab textbook, on "Cradle of Life", 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 three textbooks, and you are responsible for covering that; know what the key terms and the 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.

Study Guide: part 1 - readings from "Cradle of Life"Last Updated  •  September 21, 2012   

There will be a few questions out of William Schopf's book, Cradle of Life.
Refer to the familiar assignments list for a review.

The Prologue, Chapter 1 and Chapter 2 will be part of this test.

 
Study Guide: part 2 - LECTURELast Updated  •  September 21, 2012    
Chapter 1 - Earth as a System
Study the whole chapter; pay special attention to the following topics:

  1. Be sure to know the concepts of Uniformitarianism, Actualism and Catastrophism
  2. Know the Nature and Origin of Rocks (Igneous, Sedimentary and Metamorphic); these topics are also discussed in much greater detail in Chapter 2
    Among other things:
    • Know Formations, Members, Groups, Supergroups
    • Know what Stratigraphy is
    • Know the three principles of Steno (superposition, original horizontality and lateral continuity)
    • Know what the rock cycle is and how it works
    • Know global dating of the rock record, including the use of fossils and radioactive decay
    • Know what Eons, Eras, Periods and Epochs are
    • For this test, memorize the names and the numerical age of Eons (Hadean, Archean, Proterozoic and Phanerozoic) and Eras (Paleozoic, Mesozoic and Cenozoic), as from figure 1-11 on page 11
    • From the same figure, learn the names (but not the numerical age yet) of the Periods of the Paleozoic (Cambrian, Ordovician, Silurian, Devonian, Carboniferous {which is further subdivided into Mississippian and Pennsylvanian, but only in North America} and Permian), Mesozoic (Triassic, Jurassic and Cretaceous) and Cenozoic (Paleogene and Neogene); for this test, you do NOT need to memorize the Epochs of the Cenozoic
    • Know the difference between a geologic Period and a geologic System (page 12 on the textbook)
  3. Know the paragraph on Imaging Earth Below (Earth's core, mantle and crust, and the concepts of lithosphere and asthenosphere)
  4. Know Plate Tectonics
  5. Know the Water Cycle
  6. Know Directional Change in Earth's History
  7. Know Episodic Change in Earth's History

Chapter 2 - Rock-Forming Minerals and Rocks

  1. Know the Structure of Minerals: elements, atoms, ions, isotopes, subatomic particles, types of chemical bonds
  2. Know the geologic utility of both stable and unstable isotopes; remember the discussion (with examples) on stable oxygen (O) and carbon (C) isotopes and unstable, or radioactive carbon isotopes
  3. Know the main properties and the main families of minerals
  4. Know all the textbook material on igneous and metamorphic rocks, and pay special attention to sedimentary rocks, including sedimentary structures. (do not forget to integrate the materials on sedimentary rocks from the textbook with those from the lab manual. See below under "Study Guide: part 3 - LAB")
  5. Remember the discussion of pelagic chemical (limestones and cherts) and non-chemical (red clays) sediments, and their origin (see also Chapter 3). In particular, review your notes on the C.C.D. (Carbonate Compensation Depth).
    Know the names of the planktonic organisms involved (coccolithophorids, foraminifers, diatoms, and radiolarians: which is which, in terms of phytoplankton/zooplankton and in terms of calcareous vs. siliceous shell).

 
Study Guide: part 3 - LABLast Updated  •  September 21, 2012    

Chapter 1 - Sedimentary Rocks in Hand Sample

You MIGHT be asked to identify a few hand samples. In that case, you will be provided with a copy of your lab manual flowchart (Table 1.1A, page 5) and rock identification form (Table 1.1B, page 6), and bottles of diluted HCl will be available.

  1. Know the introduction to the chapter (basic information)
  2. Know the texture of all kinds of sedimentary rocks
  3. Know the rock names and diagnostic features, as from Table 1.1A, page 5
  4. Know what matrix and cements are; be aware that, together with grains and pores they make up for the possible four components of a clastic sedimentary rock or sediment
  5. Know about hardness, color and bedding

Chapter 2 - Textural Clues to the History of Sediment

  1. Know Particle Size and Sorting
  2. Know Grain Shape
  3. Skip size distribution of coarse gravel (there will be no questions on this paragraph)
  4. Review Questions for Discussion (page 16)

Chapter 3 - Sedimentary Rocks under the Microscope

  1. You will not be asked to identify a rock under the microscope, BUT:
  2. Know the introduction ("Basic Information": know what thin sections and acetate peels are, but I will not ask you how to prepare an acetate peel)
  3. Know textures of sandstones
  4. Know textures of carbonate rocks (be sure to know Folk's classification, including the three components grains, cement and matrix; know the four major types of grains, as from page 23 of your lab manual; know how this classification differs from Dunham's (on the same page, and also in Table 3.2), and know the difference between micrite and sparite)
Make sure to check the key to this lab.
