Week 8
  1. Textbook: For this week, relevant sections include Chapter 2 (2.1-2.16, and 2.30) and Chapter 3.
  2. Lab: your posters about Mecca Hills are due on Thursday. The map for everyone is in the back of the room.
  3. The super learning opportunity (in take-home form): Your exam will occur over 8th weekend. We can talk about possible topics on Tuesday in class. I'll give you the exam on Thursday and it will be due the following Tuesday.
Week 7
  1. Textbook: read Chapter 11 (folds), Chapter 12 (foliation), Chapter 13 (lineation), Chapter 14 (boudins) and Chapter 15 (focus on 15.1 and 15.5). If you are lacking time to read, at least look and think about the figures.
  2. Your sixth image assignment is due next week. You've got a choice this week: either this image 1 or image 2. As usual, here is the blank form to sketch on. HINT 1: The orangish coloring is on image 1 is just a surficial stain. Ignore. HINT 2: Here is a zoomed out image for showing a bigger view of the outcrop for image 2.
  3. Lab: your posters about Mecca Hills are next week on Thursday. Remember these are supposed to be low-tech but informative. My advice: don't make this out to be a bigger project than it should be.
Week 6
  1. For Thursday class: complete the two half-sheets. And be ready to discuss the interpretations for the image from Tuesday.
  2. Work on your Mecca Hills mapping project this week. The finished posters will be due on Tuesday of Week 8.
  3. Lab for next week: the second round of SAF talks. Here's the form you need to complete and bring to lab.
  4. Image: your fifth image assignment is due next Tuesday. NOTE: The image is taken looking down at a horizontal outcrop. There is some rubble at the top of the photo - don't bother to sketch this; it has nothing to do with the main structure. Here is the image and the blank form to sketch on. Two tips for this week: (1) Remember to describe the thickness of layers in words as part of your observations. (2) Draw a cartoon in the interpretation section to help explain your answer.
Week 5
  1. Here is a handout about the field trip, including a suggested packing list. Remember, the bus leaves from the loading dock at 5 am on Thursday morning.
  2. For Tuesday: your image is due and you are supposed to complete the double-sided sheet with Mohr circles.
  3. Extra map practice: I put a file called "map_practice.pdf" in the course folder under Course Materials. There are three structure contour maps in the file. It's totally optional; I don't have a key for it but you can come in and ask questions.
Week 4
  1. Textbook: Read Chapter 4 about stress. Also skim chapter 5.
  2. Lab is due at the start of Tuesday.
  3. Image: your fourth image assignment is due next Tuesday (i.e. February 3). NOTE: The image is taken looking down at a horizontal outcrop. There is some rubble at the top of the photo - don't bother to sketch this; it has nothing to do with the main structure. Here is the image and the blank form to sketch on.
  4. The first batch of San Andreas fault talks are in lab on Thursday. Please load your slides onto the lab computer (desktop) before the start of lab. Bring your completed form for me to grade on. Also, here is a handout that I made about giving talks, with additional tips from those we discussed (and few of you wrote down) in class. The pdfs of each paper are located in the course folder for the lab. I also put some slides that some may find useful in the same location.
Week 3
  1. Textbook: Still Chapter 8. (And for Chapter 7, the best sections were 7.1-7.3 and 7.8).
  2. Lab #2 is due at the start of lab on Thursday.
  3. Lab #3 will start during common time, fueled by pizza. Note: the lab will be due on Tuesday during Week 4, at the same time as your image is due.
  4. Image: your third image assignment is due next Tuesday. Here is the image and the blank form to sketch on.
  5. The second SAF discussion will be on Thursday. Bring your typed answers to the questions to class.
Week 2
  1. Textbook: Read Chapters 7 and 8.
  2. Lab #1 is due at the start of lab on Thursday.
  3. Image: your second image assignment is due next Tuesday. Here is the image and the blank form to sketch on.
  4. We will have our first SAF discussion on Thursday. Bring your typed answers to the questions to class.
Week 1
  1. Textbook: The first reading assignment is Chapter 1 and the appendix reading about stereonets.
  2. Please buy a protractor from the bookstore (or bring the one from your majors kit). I recommend the red see-through kind where the protractor is within a ruler.
  3. Bring to class each day: protractor, colored pencils, textbook.
  4. The California map assignment is due on Thursday.
  5. Image: Your first image assignment is due next Tuesday at the start of class. Here is the image and the blank form to sketch on. This assignment will be graded on a ten-point scale: 3 for the sketch, 3 for the observations, and 3 for the interpretations. The last point is reserved as a je ne sais quoit point, which is awarded for special reasons that are hard to explain.
