concepts from chapter 6
  These exercises explore concepts from Chapter 6 including the traction vector, the stress tensor, normal and shear tractions on geological surfaces (e.g. faults), principal stress magnitudes and directions, stress states within mineral grains, and the use of Kirsch's solution to study wellbore stability and hydraulic fracturing.
 
Solutions:
   
stress perturbation during magma injection at Spanish Peaks
  The stress field from the Kirsch solution for a cylindrical hole in an elastic body is investigated as a model for the stress perturbation around the magma chamber under West Spanish Peak, Colorado. Stress trajectories are computed and compared to patterns of radial dikes in order to estimate the magma pressure and remote horizontal principal stresses at the time of dike intrusion.
