(Taylor & Francis Group, 1989-07-01)Rotoehu Ash, from the Wairoa River mouth, is dated at 71 000 ± 6000 years by the 230Th-238U radioactive disequilibrium system. The age is significantly older than the commonly quoted 14C age of 41700 ± 3500 years B.P. ...
-
(Taylor & Francis Group, 1996-06-01)Caves overrun by glaciers are known to accumulate dateable evidence of past glacial and interglacial events. Results are reported from an investigation of Aurora Cave on the slopes above Lake Te Anau in Fiordland. The cave ...
-
(Taylor & Francis Group, 1975-03-01)A landslide that occurred in the upper Acheron River valley (S74) has been radiocarbon dated (NZ547) at 500 ± 69 years b.p. There is evidence that it was initiated by an earthquake caused by movement on the Porters Pass ...
-
(Taylor & Francis Group, 1987-07-01)A Bayesian procedure for examining whether the time-space variation of the magnitudefrequency relation conforms with the exponential distribution or not is proposed. The relation in each time-space segment is obtained as ...
-
(Taylor & Francis Group, 1982-10-01)On 10 October 1978, a landslide on the coast near Mt Vulcan, North Canterbury, New Zealand, was observed taking place, at high tide, by 2 fishermen. A 4 ha block of massive sandstone, 10 m thick, slid down an impermeable ...
-
(Taylor & Francis Group, 1966-07-01)Sir Charles Cotton has published his contributions to science in many forms—notes, reviews, articles, and books—and in many media in various countries in the world. He has, for example, had papers published in scientific ...

(Taylor & Francis Group, 1966-12-01)In the “Bibliography of New Zealand Geology to 1950” to be published shortly as N.Z. Geological Survey Bulletin 65, there are 45 entries under the name of R. S. Allan. A few only of these are repeated here, under the heading ...
-
(Taylor & Francis Group, 1987-01-01)The distributions of sterane and terpane classes of biological marker hydrocarbons in seven oils and in selected sediment extracts from the Westland basins region have been examined by computerised gas chromatography/mass ...
-
(Taylor & Francis Group, 1958-05-01)Posthole boring of dune sands on Nine Mile Beach, south of Cape Foulwind, Westport, shows that the surface sand to a depth of 20 ft contains an average of 5.50% of magnetically recoverable ilmenite. Boring of dunes covering ...
-
(Taylor & Francis Group, 1981-07-01)A brief review is given of studies of the secular variation of the geomagnetic field in the Pacific region. Compared to the rest of the world the non-dipole field is of small amplitude and there is evidence from observatory ...

-
(Taylor & Francis Group, 1990-01-01)Poorly preserved trilobites from the Baton Formation at Baton River, New Zealand, are assigned to Acaste sp. indel and Acastella sp. indel The occurrence of these genera in both New Zealand and Victoria confirms the close ...
-
(Taylor & Francis Group, 1959-12-01)Following the initial discoveries of Hochstetter in 1859, geological research in the province was for a long time almost entirely the work of officers of the early Geological Survey. This period lasted until the late ...
-
(Taylor & Francis Group, 1991-03-01)A glauconitic, sand‐filled, vertical clastic dike (>10 m high, base unexposed) and two associated sand‐filled sills in late Miocene mudstone (c. 6 Ma) near Annedale, Northern Wairarapa, New Zealand, pinches out upwards and ...
-
(Taylor & Francis Group, 1978-07-01)Trace and major element analysis of coarse porphyritic basalt occurring as blocks included in pantellerite pyroclastics on the eastern side of Mayor Island suggests that the rock may represent the parent or a partial ...
-
(Taylor & Francis Group, 1985-04-01)Four established methods of analysing particle sizes finer than 63 μm are compared: pipette, hydrometer, SediGraph, and hydrophoto-meter. Four samples were analysed: a high plasticity mud, a p-layer loess, a highly micaceous ...
-
(Taylor & Francis Group, 1967-10-01)New geological mapping of the Mount Tongariro massif indicates that it is a multiple volcano, the cones of its southern portion, apart from Mount Ngauruhoe, being substantially older than those of its northern portion where ...
-
(Taylor & Francis Group, 1970-10-01)Plant microfossils from c. 20 ft below the Upper Waipipi Shellbeds (Middle Pliocene) indicate a climatic episode as cold as the climate of the Hautawan Stage (lowermost Lower Pleistocene).
