摘要:

Three phases of folding have been recognised in the greywacke-Alpine schist transition in the Torlesse terrane rocks of the Callery River headwaters, Westland. The first phase was synmetamorphic and isoclinal (F1). This deformation resulted in variable textural reconstitution of the rocks (textural zones 2 and 3). Subsequent deformation has disrupted the textural zone boundaries, so that the boundaries have been folded almost isoclinally (F2) and refolded by an upright antiformal structure (F3) correlated to Alpine Fault related structures.
