Tilting of active folds and drainage asymmetry on the Manawatu Anticlines, New Zealand : a preliminary investigation

Auteur(s) et Affiliation(s)



Description :
The apparent southward tilting of 5 anticlines in the Manawatu, North Island, New Zealand, is investigated using 2 drainage basin analyis techniques : the transverse topographic symmetry factor (T) and the asymmetry factor (AF). The techniques are used to determine whether westward-flowing trunk streams on the gentle western limbs of 5 anticlines are migrating southwards across their drainage basins, concomitant with down-tilting of the fold axes. While results show potential for the techniques to be applied in such a tectonic setting, the findings are inconclusive.
