Figure 12

Model 4 (Passive continental margin); Second invariant of the strain rate and stress within the model lithosphere after 25 km, 250 km, and 500 km of shortening. Only the central portion of the model is shown. The horizontal coordinates indicate positions relative to the mesh diagrams in Figure 11. The gray scale represents strain rates from 10-14 s-1 to 10- 11 s-1 and stress from 0 to 400 MPa, with white indicating the highest value and black indicating the lowest. The crust/mantle boundary beneath the continental interior is indicated at the right (c/m). Vertical exaggeration is 2:1. Color images of these figures can be viewed on the internet with a World Wide Web (WWW) browser at http://zephyr.rice.edu/department/faculty/sawyer/sawyer.html. The features discussed in the text are greatly enhanced in the color images.
