To quickly assess the difficulty of the text, read a short excerpt:
Figures 5 and 6 are folds whose axial lines pitch about 55® S.E., and whose axial planes dip about 50® ]?.E. It will he seen hy the attitude of the folds that, while the formations were F:till flat-lying "beds from what was originally the southeast direction, they had a tendency to come up over beds to the northwest, as in Fig. 5a, giving a differential movement of the kind diown by the arrov/s and the strain ellipsoid. This would indicate that the formations had been subjected to a pt^essurc a...cting in a southoast-northv/est direction, resulting in folding and shortening. The thrust would bo from the southeast rather than from the northwect because the pitch of the axial lines is toward the southeast. >V.M
