I.  COURSE GOALS & OBJECTIVES

Since Rocks are the basic building blocks of the Earth, this course is designed to give the student a fundamental background in rocks, necessary to understand the Earth.  The student will learn the  principles behind rock forming processes and will learn to examine rocks in hand specimen and thin section, both as a means of identifying and describing the rocks and as a means of extracting clues to formulate hypotheses about how the rocks formed in nature. 

II. TEXTBOOKS

Required Textbooks:

  • Petrology, Igneous, Sedimentary & Metamorphic 2nd Edition by Blatt & Tracy W.H. Freeman & Co. 1995 (B&T)

  • An Introduction to the Rock Forming Minerals, 2nd Edition, by Deer, Howie and Zussman (text used last semester in Mineralogy)

  • Supplementary Textbook:

  • Petrography, 2nd Edition by H. Williams, F.J. Turner, and C.M. Gilbert: W.H. Freeman Co. (WTG) (Several Copies are available in the Lab)

  • Additional materials required for lab:

    (1) A handlens, available from the Tulane Bookstore

    (2) A double sided high density 3.5" floppy disk.

    (3) Rectilinear and Triangular graph paper.

    III. COURSE GRADING

    The course grade will be determined on the basis of the number of points scored out of a possible 1000 points. These points will be apportioned as follows:  
    Homework and Labs 15%
    Lab Midterm 15%
    Lab Final 20%
    Lecture Midterm 20%
    Lecture Final 25%
    Field Trip Participation 5% (see below)
    Attendance in class and lab is required (see Tulane University Undergraduate Catalog, p. 14) and is essential for you to get the most out of this course.  Grades will be lowered as a result of excessive absence from either lecture or lab.
     
    Field Trip:
    The Field Trip is scheduled for April 10, 11, 12 and 13 (Thursday through Sunday). Make plans now so you won't have any excuses for not attending. (No excuses will be accepted.)
