Abstract
Abstract The relationship between the mineralised Hyde‐Macraes Shear Zone (HMSZ), an extensive, low‐angle, semibrittle structure in the Otago Schist Belt within the Haast Schist, New Zealand, and folding events affecting metased‐iments is documented. The shear zone postdates F3 folds, although it is subparallel to S2, a shallow, north‐dipping penetrative cleavage. Evidence of the first shortening phase is only rarely preserved because initial fabrics are transposed. D2 resulted in a strong mineral elongation (L2), a penetrative cleavage, and isoclinal folds. D3 produced generally asymmetrical northwest‐plunging folds in S2 at all scales but of variable intensity. In regions where intense D3 shortening has occurred, L2 is apparently rotated into parallelism with F3 axes. A fourth event resulted in micro‐ and mesofolding about a north‐plunging axis; after this, D5 produced a northeast‐trending micro‐crenulation. The HMSZ nucleated on the lower limb of an inclined macroscopic F3 fold, post‐F3 but pre‐D4 vein...
