摘要:
Two newin situfossil faunas are described from a melange terrane within Torlesse rocks in the southern Ruahine Range, North Island, New Zealand. T23/f7530 is an isolated, allochthonous limestone block containing foraminifera, brachiopods, gastropods, bivalves, ammonoid fragments, ostracods, conodonts, crinoids, echinoids, and fish remains. The bivalves includeHalobia lillieiMarwick of Oretian age (Late Triassic; Late Karnian-Early Norian). Locality T23/f3 is a massive argillite, probably of autochthonous origin, containingRetroceramus (Retroceramus) haasti(Hochstetter) of Ohauan age (Late Jurassic; Late Oxfordian-Kimmeridgian). Stratigraphic and structural relationships between the two localities are uncertain. The conodont fauna from T23/f7530 provide a possible new line of correlation between New Zealand Triassic sequences and the world standard for Late Karnian-Early Norian time.
