Abstract
The structure of the Mt Cook Range is dominated by large, north-facing, steeply plunging, late folds. The Main Divide, on the western side of Hooker Valley, is formed of west-dipping beds, broken by west-northwest-dipping faults. Four episodes of folding occur in the Main Divide:F1 are possibly soft-sediment folds; F2 are isoclinal and display an axial plane schistosity; F3 are southwest-trending upright folds similar to those further west in the Alpine schists; and F4 folds are related to faulting. The rocks in the Main Divide are warped about steep axes; these structures may correlate with the late folds in the Mt Cook Range, but their relationship to the other folds in the Main Divide is unknown. The relationship between the large steeply plunging folds in the Mt Cook Range and similar structures elsewhere is discussed; we consider that the structures in the Mt Cook Range formed with initially steep plunges.
