摘要:

A stratigraphic column showing relative lengths of the Tertiary series and stages of New Zealand is presented. Estimates of the relative durations were derived through comparisons of estimates made by five leading New Zealand paleontologist-stratigraphers based upon their concepts of evolutionary changes, thickness of sedimentary sections, and distribution of rock units.

摘要:

In four yellow-brown earth and podzolised yellow-brown earth soils derived from rhyolite, much evidence concerning mineralogical changes attendant upon weathering and podzolisation has been obtained, and an explanation of the formation of the soils has been offered.

摘要:

In the Waipaoa River catchment, clay minerals were used to identify the source rocks contributing appreciable quantities of fine sediment to the floodplains of the Lower Waipaoa River valley. The conclusion arrived at is that all easily erodible rocks contribute material and that sediment is not all derived from rocks showing spectacular forms of erosion. The clay mineral, montmorillonite, is present in all rocks of the catchment and is partly responsible for the high degree of erosion in the crushed argillites at the headwaters of Waipaoa River.

摘要:

Statistical analysis of bedding surfaces, shear surfaces and joint planes indicates that a basement series of greywackes and argillites has undergone at least two phases of folding of contrasting styles. It is suggested that an earlier phase of large-scale flexural slip-folding about a N.N.W. axis, β, along with attendant overturning, was followed by a phase of folding parallel to B induced by movement on oblique shear surfaces; the B axes are marked by corrugations. An anticlockwise rotation of approximately 30°, bringing β to the present N.W. trend during overturning, is suggested to explain its relation to the N.N.W. trend of B.

摘要:

Near Cape Chocolate, two streams fed by the Hobbs and Salmon*Because of duplication, Salmon Glacier is a new name proposed for the Davis Glacier of Taylor (1911), and others, by Mr G. Warren, Trans-Antarctic Expedition. The name has yet to be approved by the N.Z. Honorary Geographic Board. As a consequence of the change in name, the name Salmon Creek has been proposed instead of David Creek for the stream draining from Salmon Glacier. Hobbs Stream has been proposed for the meltwater stream draining from the Hobbs Glacier.Glaciers flow to a bay partly enclosed by a breached loop of an ice-cored terminal moraine of Hobbs Glacier. A hay-head delta constructed by the streams is diffed at its outer edge, and covers a marine bench which rises to a height of about 30 ft. Along the streams, between the delta and glaciers, are terraces cut in moraine and fluvioglacial sediments.

摘要:

It is iff,probable that the sinuosity ot the Wellington Fault scarp has been notably increased by localised back.wearing, North-east of the Wakatikei River the valiey-side scarp of the Hutt Valley is half a mile out of alignment with the Wellington Fault and it is possible that its position is determined by a splinter oren échelonfault, The long straight segment of the valley side south-west of the Wakatikei confluence has not necessarily been cut far back by the Hutt River, which more probably has merely retouched the youthful form of a fault scarp, perhaps removing soliflual debris that threatened to smother it, The view that the valley-side scarp is a young fault scarp is supported bv the asymmetric form of the valley.

摘要:

Correlation by lithology of stages in the Eastern Basin of New Zealand is outlined. Lateral facies changes in the Eastern Basin are consistent in time and place from the Upper Cretaceous to the Lower Tertiary and indicate that finer sediments were laid down in the central, presumably deepest part of the basin. After the close of the Eocene relief in the Eastern Basin became irregular and a sedimentation inconsistent in place and time took place. Tectonic deformation affecting the Eastern Basin was apparently not accompanied by severe breaking up uf the undermass prior to the Middle Cretaceous, but was so in the time afterwards. The central area of the Eastern Basin and the relief of Central New Zealand appears to have been tectonically low during the Upper Cretaceous and Lower Tertiary. After the Eocene the central area of the basin broke up into an irregular arrangement of tectonic highs and lows while the relief of Central New Zealand remained low.

摘要:

Recoveries of drift cards from releases made off the New Zealand coast in the twelve months preceding July 1954 demonstrate the existence of a coastal circulation, dependent on the surrounding oceanic currents and the topography for its basic pattern.

摘要:

A pattern of movement of surface water in Hawke Bay has been indicated by the use of plastic covered drift cards. The results, generalised over a period of three summer months, indicate a strong central flow of water into the bay diverging to move north and south parallel with the shore.

摘要:

Triassic sediments are preserved in a narrow infaulted outlier at Lake Fergus on the western side of the Hollyford Fault. Three fossil species show that the beds are Otamitan.
