Field trips: Three field trips will be conducted. Students are encouraged to attend all three, however, the first two, scheduled for 9/24 and 10/14 are optional in that a student may choose one or the other. The third field trip, on 11/4-5 is mandatory. Thus, overall, students are required to participate in two weekend field trips.

Required materials for field trips: Textbook, hand-lens, mechanical pencil, colored pencils, graph paper, grain-size chart (example), field notebook, rock hammer, outdoor gear for the field trips boots or sturdy shoes, hat, sunscreen, water bottle, rain gear, day pack.

Optional: acid bottle, pocket knife.

Description: Description, origin, and distribution of sediments and sedimentary rocks. Two mandatory weekend field trips.

On-line materials: Laboratory assignments, lecture PowerPoints, and associated readings will be posted on the class elms website. The syllabus and lecture notes are at http://www.geol.umd.edu/~jmerck/geol342/. It is your responsibility to print out the lecture notes and laboratory assignments before the appropriate classes.

Class description and attendance policy: Attendance won't be taken, however lecture attendance is essential if you wish to have a good outcome. Exams will be based on lecture material including material from discussions, reading assignments, and field trips. Posted web notes are intended as a synopsis of lecture material only. Readings reinforce lecture material, however lectures may depart significantly from readings.

Final grades: Your final letter grade will be based on the following elements:

Appeal of grades: You may appeal your grade on any exam prior to the posting of final course grades. In this as in all college courses, you should retained all graded items until proper grades have been recorded on your transcript.

Prerequisites: Students enrolled in GEOL342 are expected to have passed GEOL322 - Mineralogy or its equivalent at another institution with a grade of C- or better, or to have obtained specific permission from the instructor to enroll.

Grade calculation: With diligent work it is possible for each student to attain an A in this class. Grading will be based on points gained from the examinations listed above, as follows:

100-97% = A+, 96-94% = A, 93-90% = A-,
89-87% = B+, 86-84% = B, 83-80% = B-,
79-77% = C+, 76-74% = C, 73-70% = C-,
69-67% = D+, 66-64% = D, 63-60% = D-,
<60% = F

Laboratory: A short quiz based on the posted reading(s) and exercise for the laboratory (or of recent lecture material) will be given in the first 10 minutes of each session. The full laboratory time should be utilized to complete the exercises and ask questions of the teaching assistant. In some circumstances the materials (and teaching assistant) may not be available in non-laboratory times. The three scheduled petrography laboratories will be conducted in GEO 2117. Use of the petrographic microscopes requires special training and care. Exercises from the previous week are due at the beginning of the laboratory; there will be a 10% deduction of the grade for every day a laboratory is turned in past the due date. Missed laboratories may be made up only with university-approved excused absences; there will be no make up of Laboratories II (sieve) and III (pipette), which require group participation.
