Figure F85. Equal-area stereographic projection demonstrating the potential effect of tectonic tilting on originally horizontal, normal, and reversed remanence directions, Hole 1256D. Purple line = locus of remanence directions resulting from tilting around a horizontal rotation axis trending 340° (parallel to the reconstructed trend of the East Pacific Rise at 14 Ma; Wilson, Teagle, Acton, et al., 2003), with numbers indicating the amount of tilting in degrees. Dashed lines = lines of equal inclination. Note that steepening of the remanence by 10° requires tectonic rotation >20°.
