ERTH 203/206, Earth’s Crust
Overview of the evolution of the crust of the Earth, the major rock types and processes that form it, and the main methods used to study it. Topics include: mineralogy, igneous, sedimentary and metamorphic petrology, structural geology, subsurface fluid flow, and petroleum geology. Field trips.
 
ERTH 203 and 206 share lectures and labs, however, ERTH 206 students (principally petroleum engineers), are not required to attend all of the lectures and labs.  ERTH 203 is a 4-cr hr class, whereas ERTH 206 is 3-cr hrs.  All students must enroll in an associated lab (203L or 206L depending).  The lab grade is included in the calculation of the final class grade (i.e., you will not receive a separate lab grade in this class).

Additional readings are from Davis and Reynolds, 1996, Structural Geology of Rocks and Regions (on reserve in the library) are indicated by “DR” in the schedule.  
 
 
COURSE OBJECTIVES: Students will learn the common minerals and rock types that make up the Earth’s crust, the processes involved in their formation, the common tectonic settings of these processes, and the processes and products of crustal deformation.
 
EXAMS:
    All exams will be closed book.  Exam 2 and the final will be comprehensive, but will emphasize the new material.  Exam questions will be mainly short answer with a few multiple choice.  Bring a mechanical pencil –– you may have to make some small sketches.  The exams will cover mainly material discussed in the lecture.  Consequently, students who frequently miss lectures will do very poorly in the course.
 
    If you think an exam question has been graded unfairly, please bring it to our attention. We encourage you to do this because mistakes in grading are occasionally made in all classes. However, beforehand please look through your lecture notes, the book, or other sources to document your case (i.e., information that supports your answer).
 
    Policy on cheating: Past experience and complaints from students make articulation of a policy on cheating necessary.  If you copy answers from another student, are caught with a crib sheet, or in any more creative way attempt to cheat on an exam you will immediately be given a failing grade for the course.  Furthermore, we will petition the Dean of Students to have you placed on probation or suspended from school.   Cases of plagiarism in the written assignments will also be dealt with harshly.  Be sure that you understand what plagiarism is (the NMT Library has an excellent web site, as does the NMT Graduate Office).  Although students are encouraged work with others on laboratory and field trip assignments, the work turned in must be your own (e.g., wording your own; map contacts drawn independently, not copies from someone else’s map).  If you are unclear about this please consult with a faculty member

LAB AND FIELD TRIP EQUIPMENT:
 
    (1) Hand lens (7-14X), (2) grain size card (buy from Barbara Fazio in EES office), (3) rock hammer, (4) field notebook, (5) mechanical pencil (0.3 – 0.5 mm; very important!), (6) clipboard or map board, (7) Two disposable drafting pens (i.e.,  disposable Pigma MICRON from Sakura Co.,  or ZIG MIllenium from Kuretake Co.):  one #005 (~0.3 mm line width) in black, and one #01 or #02  (~0.5 mm line width) in red or green.  Ball point and "Sharpie" pens are not acceptable,  (8) A set of ~12 color pencils, erasable colors are preferable (i.e., Colerase brand or erasable Crayola brand), (9) Protractor and straightedge ruler(s) with divisions of tenths of inches and millimeters.  Used for both field and lab work, GA prefers the C-Thru brand 6" rulers that combine all these characteristics. They're cheap so buy two as you are likely to lose one in the field, (10) Zip-A-Dip brand protractor for use in cross section construction for apparent dips (available through Miners catalog for <$5.00;  see this web site: (http://www.minerox.com/index.cfm?fuseaction=product.display&product_id=974), (11) About 6 sheets of 11" x 17" vellum cross section paper with 10 x 10 squares per inch (this is expensive so share a pad of 50 sheets with other students), (12) 8.5" x 11" tracing paper for use with stereonets, (13) Calculator with trig functions, (14) pocket knife,  (15) sturdy shoes, (16) hat (optional), (17) sunscreen (optional), (18) water bottle (depending on weather), (19) day pack.  Also, a digital camera may be useful to document field relationships, and binoculars are often useful in the field.  Note that most of these items will be useful in future Earth Science courses.
