Reactive Transport in the Subsurface

Lesson 9: Chemical Weathering



In this lesson we use a mineral reaction example to illustrate 1) how physical processes and geochemical processes are coupled in the short and long time scales, and 2) how to set up physical and geochemical processes in a 1D column in Crunchflow. The set up combines mineral dissolution (and precipitation) and physical flow processes in previous lessons. Please review these two lessons if needed.

Learning Outcomes

By the end of this lesson, you should be able to:

  • Understand the importance of mineral dissolution and chemical weathering;
  • Understand the fundamental principles and key parameters that govern chemical weathering and reactive transport process coupling in general;
  • Set up simulations in CrunchFlow with flow, solute transport, and mineral dissolution and precipitation reaction.
