"Graveyard Lab"
Summary
Because there is not a lot of surface structure to map in glacial terranes of the midwest, especially in big cities, various simulations can help. This is a "big-city" simulation of making a geologic map and interpreting the structure of a small area (a cemetery) by measuring the strike and dip of gravestones. This field activity is followed by lab work, including plotting the attitudes on stereonets and interpreting the patterns.
Collapse
Context
Audience
This is an undergraduate required course in structural geology. It is not a typical structural geology course, because Math pre-requisites are remedial only, and Mineralogy is also not a pre-requisite. The title of the course is Geologic Structures and Map Interpretation.
Skills and concepts that students must have mastered
They must know how to use the Brunton compass to measure strike and dip, and they must know how to plot on the equal-area stereonet.
How the activity is situated in the course
This is an end of a sequence of exercises which include use of the Brunton compass, as well as practice with the stereonet (two stereonet labs).
