Summary
Students will be exposed to the processes of metamorphism and diagenesis on Earth and determine which processes are dominant on Mars. Are diagenetic processes on Earth mirrored on Mars?
Learning Goals
- Observe and understand the diagenetic alteration of hematite to goethite,
- Test different variables of experimentation to understand diagenetic environment thresholds of alteration.
Context for Use
This module is meant for adaptation in an earth science course where sedimentary rock lithology and sedimentary rock processes of formation are already familiar to students. An understanding of sedimentary depositional environments would also be helpful.
Description and Teaching Materials
In-Class Activity
- In-Class Activity 1: Cooking Rocks- Did the experiment work?
- In-Class Activity 2: TBA
Homework/Lab
- Homework 1: Cooking Rocks- Diagenesis
Teaching Notes and Tips
- In Homework 1: students will need samples of southern Utah picturestone.
- In-Class Activity 1 serves as a follow-up discussion for Homework 1 "Cooking Rocks". If desired, students may complete this as homework as well.
Assessment
Methods of assessment are within each individual In-Class Activity and Homework.
