Ran in 2 of the last 7 terms. Winter 2027: scheduled, 2 lecture sections. Spring 2027: schedule not out yet.

Concepts of stress and strain; elementary rock mechanics; description and classification of folds, faults, foliations, lineations and joints; use of primary structures; introduction to geometrical analysis. Labs will emphasize geometrical problems, including geological maps and cross sections, and stereographic projection.

  • I no longer fear death, for I have drawn forty six thousand incorrect stereonets for Chancheng.
    Shoufa's great though.

  • Unfortunately it's one of those few courses that I didn't enjoy as much. It has some solid fundamental concepts and good lab component but that was about it.

  • Taken W22, this course is an absolute mess. There is a lab and a lecture component, both of which are taught completely separate from each other and by 2 different teachers.
    For the lab portion, there was practically no feedback given so you didn't know where you went wrong. Students brought this up to the teaching team. Instructors recommended going to the TAs for help, however twice when I emailed TAs with questions I received no response. In person labs were slightly better as you could ask questions to the prof/ta right there. However class averages for both the midterm and exam were at a shocking low despite being online and open book.
    The actual lectures themselves were fine and…

  • Taken over Winter 22, online.
    Lab and lecture component were not very well related, making it feel like you were learning two different courses at a time. Lab assignments were weekly, and quite time consuming, requiring lots of drawing to-scale diagrams.
    Assignment answers were not given, and feedback was very limited, usually no feedback was given. Part marks were also limited, so getting an answer wrong took off 60-70% of the questions marks, even if the steps you took were correct. (This includes the to-scale diagrams you just spent an hour drawing).
    The lecture component has no assignments, which makes it easy to fall behind. There was no practice midterm, and this coupled with…

  • ok the lecture is decent since Shoufa knows what he is talking about and is engaging and very smart. the TAs on the other hand are horrid. TA's dock marks like you are a PhD student and expect you to get perfect on all the labs. I am convinced you have to be a pro at structural geology to do well in this course. even with the lab sessions and lab videos, marks just disapear for no reason with little to no feedback. I emailed the TA for clarification several times and they essentially tell me "you did it wrong". thanks.
