I. Laboratory Course
|
|
|
GY403L Structural Geology Laboratory
|
|
|
|
|
II. Laboratory Description
|
|
|
The study of field and office techniques that are useful for classifying and quantifying
geological structures.
|
|
|
|
|
III. Laboratory Objectives
|
|
|
Upon completion of this laboratory section the student
will be familiar with field and office methods that are used as the basis
of constructing accurate geologic maps. The student will be introduced to
stereographic projections, and to statistical analysis of structural
orientation data. Laboratory methods for detecting and analyzing a
wide variety of geologic structures will
comprise the majority of the laboratory course.

VI. Procedures for Assessing Student Performance
|
|
|
You will be required to obtain certain materials to
complete the laboratory assignments. A list of required lab tools and
supplies follows:
Required Tools & Supplies
1. Drawing pencils (3 or 4H).
2. Engineers Scale (English Units).
3. Protractor (clear plastic).
4. Colored Pencils: red, green, blue, yellow, brown, orange, black, and heliotrope(purple).
5. 8.5" x 11" smooth, hard surface drawing paper, suitable for
use with a rapidograph.
6. 8.5 x 11 tracing paper.
7. Drafting tape.
8. 2 triangles (30-60-90 ). Try to find the type
with the beveled edge.
9. A compass for drawing circles. You do not have to get an expensive
engineering compass, any type will do.
10. Rapidograph Set (Technical Drafting Pens) - at least two sizes (0 and 2).
11. Eraser
12. Two Notebooks, 3-ring binder type.
Optional Tools
1. Drafting Board - these can be very handy if you want to work on your
labs at home.
2. Field notebook for the field mapping exercise.
3. Clipboard for field mapping exercise.
4. USB “Jump drive” for storing applications and data.
Exam & Assignment Percentages
The percentage weightings for exams and assignments are as follows:
LABORATORY GRADE PERCENTAGES
Average of lab assignments: 50% of Lab grade
Lab Practical exam: 50% of Lab grade
Lab Assignment Page Format
Page size is letter (8.5" x 11"). Use this format for each
problem unless otherwise instructed. In some cases a scale or north arrow
may not be required.

A 3-hole punch binder notebook will be required for the
lab problems. Having your problem sets together in one place will aid you
in this course and in the future. Notebooks will be kept according to the
below guidelines. Failure to use guidelines will result in the deduction of
points:
1. Exercise assignment sheet(s) for the week will precede all problems
for that week.
2. Labs must be done on lineless paper and entered into the notebook (i.e.
use a 3-hole punch).
3. Only one problem or portion of a problem per page.
4. Problems must be labeled on every page as shown below:
5. ASSIGNED SCALE MUST BE USED. Failure to comply will result in no credit
for that problem.
6. All problems should be done in black ink with a rapidograph, unless
otherwise instructed.
7. Neatness and accuracy go together. Accuracy required for full credit
will be determined by problem difficulty and by scale. Neatness will
account for 10% of each lab assignment.
8. Some problems will require a written portion outlining the procedures
used to solve the problem. The written portion should be placed in the
bottom third of the problem construction, or it should be entered beginning
at the top of a separate sheet.
Exercises assigned in lab will be due at the beginning of the next
laboratory period unless otherwise announced. Since I always go over the
answers to the previous assigned lab at the beginning of class, there is no
possibility of turning in a "late" lab.
The lab period will be devoted to a review of previous assignments and
instruction on and demonstrations of new problem material. All assignments
are to be done as independent work. I encourage you to discuss the
principles involved with your classmates. However, if you depend on your
fellow class members too heavily you will have great difficulty with the
laboratory final examination. Because this examination composes a large
proportion of your laboratory grade, it is unlikely that you can pass the
laboratory if you rely heavily on your classmates, or old labs from former
students, for answers to weekly assignments. It is very important that, if
you are having problems, you should seek the instructor or laboratory
assistant for assistance. Most principles involved with a given lab are
built upon those learned in previous labs, so you cannot afford to fall
behind in this class.
Students should note that there is a required Friday-Sunday field
trip for the laboratory during the 5th week of class. Everyone goes- no
exceptions! This field exercise will be one of the few times prior to a
summer field course that you will have a firsthand opportunity to learn the
art and science of geological field mapping. I strongly suggest that you
make the most of the opportunity by approaching the problem with an open
mind and a "can-do" attitude.
A second required field trip to the Llano uplift is required during the
12th week of class. Many of the structures discussed in class will be
demonstrated during this field trip.

VII. Instructors for the Course
|
|
|
Instructor: David Allison
Office: Room 344 LSCB
Office Hours: Will be posted on office door
|
|
|
|
|
|
This course is usually provided a student assistant for
the laboratory whose main function is to assist students completing the
laboratory exercises, and to assist the instructor in grading. The student assistant,
if available, will be announced during the first lab. It is recommended
that students take advantage of the knowledge available from the laboratory
teaching assistant.

NOTE TO GEOLOGY MAJORS: Every semester the
Geology/Geography Department designates a specific week as advising week.
This is the period designated for you and your advisor to meet and discuss
your progress and future courses. Please take advantage of this designated
time- your advisor may refuse to advise you at other times. Be aware that
you should meet with your advisor every quarter so that the departmental
secretary can mark you from the registration "hold" list. It is
your responsibility to make an appointment with your advisor, and to make
sure that he/she marks you off of the registration "hold" list
after you have been advised. If you are on the hold list you will not be
able to register with phone registration. You can check with the
departmental secretary each semester to determine the dates of advising
week.
