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:

Earth Materials by Hefferan and O'Brien (H&O)

An Introduction to the Rock Forming Minerals, 2nd Ed., by Deer, Howie & Zussman (DHZ)


Supplementary Textbook:

Petrography, 2nd Edition by H. Williams, F.J. Turner, and C.M. Gilbert: (WTG)

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%
Lecture Midterm 20% Lab Final 20%
Lecture Final 25% Field Trip Participation 5%

 

Field Trip: The Field Trip is scheduled for April 12-15 (Thursday through Sunday). Make plans now so you won't have any excuses for not attending. (No excuses will be accepted.)
 
IV.  WEB PAGE

A Web site has been developed for this course.  It  includes course materials, including a copy of this syllabus, lecture notes, announcements from the instructor, and Internet links.  The site can be found on the internet at: http://www.tulane.edu/~sanelson/eens212/

Be sure to check this web page regularly throughout the course for important announcements and updates.

In addition PDF versions of the actual lectures will be posted on the Blackboard site for this course as they become available.
