Geology: The Field -vs- The Lab
TableCan’t take all students into the field … but we can reproduce important aspects of the experience
• Decision Making• Use of Tools
• Defense of Interpretations• Time Management

What does it take to implement these four things?
Decision Making Use of Tools Defense of Interpretations Time Management
• Geologic time scale• Relative and absolute age dating• Depositional environments• Field measurements• Folding and Faulting
•Strong Background Knowledge• Plate Tectonics• Rock formation• Lat/long, UTM • Map projections• Topographic maps
•Developing a Set of Tools• Provide data• Interpret data
•Data - vs - Interpretations

What does this mean for exam questions?
•Knowledge-Based• Multiple choice• Short answer• Diagrams
•Tasks• Application• Interpretation• Integration of multiple data sets
•Interpretation Tasks• Higher-level application of tools and data sets• More

•Knowledge-Based• What is the contour interval?• Of points I, E, G, and D, which is at the greatest and least risk for flooding? Why?• If a spring were sourced at the red dots, draw the path the water would take.

•Tasks• Draw a topographic profile from A to E.• A bed outcrops at points B, J, and D. Determine the strike and dip of the bed.• If the “Photo” was taken facing west, draw a dot where the photographer was likely standing. Why there?N

• Interpretation Tasks
• Using an equal area stereonet, find the strike and dip of a bed with the apparent dips (036, 25E) and (197, 65E).

• Interpretation Tasks
• Describe the type of feature depicted in the stereonet plot in detail
• Is this feature likely to be the result of one, multiple, or a progression of deformation events?

• Interpretation Tasks
•Complete the block diagram and label any major features

• Interpretation Tasks
• Draw a cross-section from A to A’• On your cross-section, label the areas of greatest and least confidence and explain
