Rock Evolution and Change


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

Students will be able to:
  • Observe and understand the diagenetic alteration of hematite to goethite,
  • Test different variables through 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.

Background materials for rock types and classification include: (this is a classification using a cooking kitchen analogy)
