In the Mind of a Stratigrapher
Exploring the Upper Cretaceous Hell Creek Formation, Montana
Part 2: Generating and Testing Hypotheses
1. What is a hypothesis?
- Frodeman, 1995
- Chamberlin, 1897
- The Scientific Method (more info)
- Problem-Based Learning
- Processes and Concepts of Geology (more info)
- The Decline of Reason? (more info)
2. List the data (i.e. observations you made) and possible interpretations.
- Compile a short list of characteristics for each unique-looking layer of rock.
- Write possible depositional environment interpretations for each unique-looking layer of rock, or lithofacies.
3. Re-write this list of "possible depositional environments" as a list of hypotheses.
4. How could you discern between possible depositional environments?
- Sedimentology and Geomorphology (more info)
- USC Sequence Stratigraphy Web (more info)
- Dryland Rivers Research (more info)
5. Are there additional data (observations) that could have helped discern the depositional environments recorded by these strata? What are these data, and how could you acquire them?
6. List final depositional environment interpretations for each lithofacies. For units that require further inspection, generate some new hypotheses and methods for testing each hypothesis.
