Abstract: The Otago Schist is part of a major metamorphic belt of the New Zealand region, the Haast Schist. The latter includes the Kaimanawa, Marlborough, alpine, Otago and Chatham schists. The Otago Schist has traditionally been interpreted as a major feature of the New Zealand Geosyncline which formed during the Rangitata Orogeny. More recent interpretations treat the Otago Schist as a metamorphic welt which straddles the Caples and Torlesse tectonostratigraphic terranes, and which formed during terrane collision beneath a fore-arc region. The Caples and Torlesse terranes are part of the Eastern Province of New Zealand, which comprises volcanic and greywacke terranes of late Paleozoic and early Mesozoic age. This publication is one of the products of a regional; geological reconnaissance of the Otago Schist between 1986 and 1990, the main objective being to locate the position of the Caples-Torlesse terrane boundary within the schist. The map also summarises new information on all aspects of schist geology particularly faults, terranes, isograds, and isotects. (auth)
