Procedures
2. Interpret the depositional environments of each core section, by reference to one of the named environments shown on the diagrams of depositional environments. In addition to those named in the diagram, you should expect to see fine-grained sediments (oozes) of the deep marine pelagic environment.
3. Apply the concept of Walther's Law to arrange the Group 1 core sections into a vertical succession, expected on a subsiding continental margin which subsides to great depths. This should show the progression of depositional environments that would be found on a rifting margin of a continent (remember the Wilson cycle). Write a short geologic history of change in depositional environments, lithology, and any additional details that you can determine from these core sections.
4. Apply the concept of Walther's Law to arrange the Group 2 core sections into a vertical succession. This should show the progression of depositional environments that would be found on a subsiding atoll island complex. Write a short geologic history of change in depositional environments, lithology, and any additional details that you can determine from these core sections.
