Review: 1.What is the orientation relationship between maximum shear stresses and principal stresses? 2. What are trajectories of principal stresses?

(A)General triaxial stress ellipsoid in perspective view. (B)Views normal to each of the principal planes of the ellipsoid. (After W.D. Means,1976)

OBSERVATION OF TECTONIC SAMPLES Observe tectonic samples in the STRUCTURAL SCOPE. Discuss what you observed with your group members. Select one representative of the group to exchange ideas with other groups in the class
