Summary

In this exercise, students work in pairs to gesture the orientations of cross-bedded sandstones, and in particular the relationship between a single cross bed and the bed sets. They do this for photos of undeformed and deformed cross-bedding.

Learning Goals

At the end of this exercise, students will be able to:

Context for Use

We use this exercise both to review primary structures and to get students thinking about 3D deformation of rocks with primary structures.

Assessment

We walk around the room, watching and talking with the students as they work through the exercise. It's a quick and easy way to assess student comprehension.
