...Stephan Bergbauer; David D. Pollard Abstract Symmetric relations between synfolding fractures and fold geometry have been used to explain the formation of fractures in folded sedimentary rocks. Based on field observations at the Emigrant Gap, a Laramide anticline located near Casper, Wyoming, we...

...: fracture density in the Emigrant Gap anticline is unrelated to horizon curvature, and synfolding fractures are aligned with prefolding fractures instead of the directions of principal curvature. Normal surface curvature by itself has only limited value in predicting strain or fracture density; however...
