Abstract
Some regional fracturing can be difficult to explain in terms of Ander son's shear-based theory of faulting. An alternative strain-based theo ry leads to definite predictions for orientations of extensional fault ing, including regional normal faulting, rift faulting, sub-vertical j ointing and cleating, and some forms of shrinkage cracking. The exampl es we present are quite typical, and qualitatively bear out the theory predictions.
