1. Logistics, marking scheme

 

Objectives of Course: The course is designed to

            1. Provide an up-to-date modern summary of information, concepts and hypotheses concerning sediments and sedimentary rocks.

            2. Gain an understanding of the processes involved in the formation of sedimentary rocks so that interpretation of the environments of deposition of recent and ancient rocks can be made.  Major emphasis will be on clastic sediments.

            3. Outline the principles of environmental sedimentology through the use of case histories.

 

            Major objectives of the field and laboratory exercises are to learn field techniques, to interpret paleoenvironments and paleohydrologic properties of sedimentary sequences, and to assess the interaction between human activities and geological processes.

 

            Most labs until the weather permits will be field trips, which are designed to allow students to test their understanding, initiative and patience. Depending on the wishes of the class and scheduling, Saturday trips may take the place of two lab periods. Every second lab a report must be written (or reported orally to the class) on the analysis of an environment of sedimentation, or a sequence of sediments or rocks.  At first it can be a frustrating experience, until one has learned what to do and how to do things.  The reward is that what is learned by "doing" will not be forgotten.

Method of evaluation: At discretion of class, to be decided during first week of lectures. A final examination will be required.
