To bring the Tuapeka Series, including the Otago Schist, into the Trias-Jura, Marshall set out this argument: “No fossil remains have yet been found in this (Tuapeka) series—at any rate, in the Tuapeka district. The nearest points at which fossils have been found are the Kaihiku Gorge and Nugget Point, twenty miles distant in a southerly direction. In these localities the rocks are greywackes, in which the grains of feldspar are perfectly fresh and unweathered. Petrologically the freshness of the feldspar alone distinguishes them from the rocks at Balclutha. So far as lithological evidence is concerned the rocks would reasonably be placed in the same series. Stratigraphically the rocks are highly inclined in both localities, but the strike is somewhat different. The importance of this should not be exaggerated, for the localities are twenty miles distant from each other, and the exact nature of the intervening country is not known. In fact, divergences of strike in one and the same rock-series are common throughout New Zealand. Stratigraphically there is no strong reason to separate the rocks at Balclutha from those at Nugget Point and they have previously been associated, notably by Hutton.” As Hutton had in 1875 divided these beds into five series, Wanaka, Kakanui, Kaikoura, Maitai, and Putataka, this reference to Hutton is misleading. The contention is of course invalid—steep beds, 20 miles apart, strikes divergent, intervening structure unknown. As for the statement that “stratigraphically there is no strong reason to separate the rocks…” there are his own statements that the structure of Otago is anticlinal and that the beds are steep and twenty miles apart. As this is on the south limb and across the strike, the beds according to these data are not the same but separated by 100,000 feet of strata. In support of the Trias-Jura hypothesis Marshall made two other references to the Kaitangata Subdivision. He asserted: “In the Clutha Valley there are typical Trias-Jura rocks at Balclutha,” and “A gradual change is to be seen along the coast from the Nugget Point to the Taieri Mouth.” For the first assertion there is no evidence; and the second is incorrect, for from Nugget Point north along the coast for 20 miles there is not one outcrop of greywacke or schist. What Marshall lumped into Trias-Jura had, as already stated, been classified in 1875 by Hutton in five series; and in the N.Z. Geol. Surv. Bull., 38, 1939, it has had to be divided into eight, seven of which have distinctive faunas. The Series recognised are: Putataka Series, Lower Oolite, Bathonian-Oxfordian. Bastion Series, Lower Oolite, Callovian. Warepa Series, Noric. Otamita Series, Upper and Middle Carnic. Oreti Series, Lowest Carnic. Kaihiku Series, Ladino-Carnic. Clinton Series, Permian or older. Tuapeka Series, pre-Clinton.
