Pleasefill out a reading log for this week. Reading logs are due at the start of class on Wednesday.
Graphics from lectures:
Several approaches will help you succeed on the first midterm exam. You should study your notes, review reading sections from the book, review lab material, and practice with old exams and study guide questions.
Copies of old exams are available to help review for the first midterm:
You may find questions on the old exams that we did not cover in lecture, lab or readings. You can ignore those questions.
Study guide for the first exam:
Questions on the study guide are similar to questions you can expect on the first midterm exam.
Lab this week-
Sandstone petrography. We will meet in the Petrography lab (Placer Hall rm. 1002). Please remember- no drinks or food in the lab.
I will pass out a copy of the lab. If you need another copy you can click here:
We will look at these thin sections in class:
S-100, S-150 S-1000, Dakota ss. (similar slides): Good examples of monocrystalline quartz, quartz overgrowths.
Dove Springs: Good examples of clay cement, orthoclase, plagioclase, volcanic rock fragments
137: Good examples of microcline
Due date: start of lab, week 12. You will have two weeks to complete this lab. This lab will receive double credit.
Grading: Neatness counts!! Part of your grade will be based on neatness and artistic drawings of sandstone composition and texture. Use colored pencils as appropriate to show the different features.
