摘要:

Pockets of high-grade manganese ore, principally braunite, are associated with red bands of basaltic lava and jasper in Cretaceous rocks in south-eastern Wairarapa. The pockets are too small and too sporadic to be of economic importance.

摘要:

The marine Tertiary rocks in the Pareora district are about 1,500 ft thick and range in age from ?upper Dannevirke Series to Awamoan. They are underlain and overlain conformably by two sets of coal-measures, each about 200 ft thick, but only the lower contains potentially workable lignite seams. The upper coal-measures of probable Southland age are overlain disconiormably or with slight angular unconformity by 600 ft of non-marine, weathered, greywacke gravels (of probable Waitotaran age) which have been folded and faulted together with the underlying Tertiary rocks. These tilted gravels are overlain unconformably by flat-lying, high-level gravels of Pleistocene age.

摘要:

Sea-level recordings have been made at Scott Base in McMurdo Sound with a modified Foxboro liquid level recorder, intermittently from March to July 1957, and continuously throughout December 1957. Because of the difficulty of operating such equipment under Antarctic conditions, the sites and methods of installation are here described in detail. Hourly values are tabulated, and the results for December 1957 presented graphically.

摘要:

The geographical configuration and hydrological character of the sub-tropical convergence, the boundary between waters of sub-tropical and sub-antarctic origin, in the vicinity of New Zealand are discussed. As a background to this discussion some data are given on the seasonal variation of surface temperature in New Zealand coastal waters. The convergence follows approximately the isotherms of 15° C in February and 10° C in August and the isohalines of 34.7 to 34.8‰ with little seasonal variation. It is characterized at the surface by steep horizontal gradients of temperature and salinity. Off the west coast of New Zealand surface water seems to be predominantly sub-tropical in character, in Foveaux Strait and off South Island being probably derived from the East Australian Current, with the northern area probably subject at times to direct entry of sub-tropical water from the north-east of New Zealand. Wind-induced upwelling may often result in lowered temperatures close to the west coast of North Island, and pronounced drops in surface temperature are consistently found between the Three Kings Islands and the mainland, and off Cape Farewell. South of New Zealand sub-tropical influence is felt in sufficient degree to raise significantly the temperature and salinity of surface waters over the Campbell Plateau. East of South Island, sub-antractic water lies off the Otago coast and extends northwards along the east coast in a narrow band as far as the Castle Point region, North Island, where the sub-tropical convergence tends to meet the coast. From this point the convergence is well defined and trends sharply southwards under the action of the East Cape Current, tongues of sub-tropical water tending to come close inshore in southern Cook Strait and off Kaikoura. Offshore from the Banks Peninsula area the convergence trends eastwards towards the Chatham Islands and probably becomes less well defined at the surface. An area of probable upwelling is noted to occur frequently between East Cape and the Ranfurly Bank.

摘要:

A Fourier investigation, of a glycerol-solvated soil montmorillonite, derived from olivine basalt, has been carried out. The investigation showed that the calculated formula [K.10Na.02H1.00] [Si6.36Al1.61[Al.82Fe3+2.30Fe2+.08Mg.48Ti.08] O18..36(OH)5.64was essentially the correct formula for the dehydrated mineral. In an electron density map of the mineral, partial resolution of the O-H and C-H planes of ions of the glycerol molecule was achieved. It was not possible to resolve the densities of the octahedral cations from those of the adjacent plane of oxygen-hydroxyl ions nor those of the tetrahedral cations from those of the adjacent plane of oxygen ions.

摘要:

Marine seismic profiles show that the thickness of unconsolidated sediments varies from a few hundred feet in the Cook Strait to Golden Bay areas to 2,300 ft in the vicinity of Marlborough Sounds. The Tertiary geosynclinal sediments of N.W. Nelson thicken northwards beneath Golden Bay. The maximum recorded velocities are consistent with the basement rock mapped in neighbouring land areas.

摘要:

Coals in the Paparoa Mine area have dry ash-free volatile contents ranging from 16% to 30%. Swelling properties are related primarily to voltaile content. The reserves of coal are considered in two groups, that of consistently exceptionally high-swelling coal with volatile contents over 21% (swelling numbers of 9+ to 9 + + +) and that of inconsistently-high to low-swelling coal with volatile contents less than 21% (swelling numbers of 1 to 9). Reserves of the former, from all nearby areas regardless of access problems, amount to 480,000 tons of measured and 425,000 tons of indicated recoverable coal. Reserves of the latter amount to 125,-000 tons of measured and 620,000 tons of indicated coal. Inferred reserves, entirely of consistently exceptionally high-swelling coal, amount to 1,800,000 tons, but much costly prospecting is essential to prove or disprove these reserves. Although the extreme north-east of the Mount Davy Block, which contains inferred recoverable reserves of 10 million tons of exceptionally high-swelling coal, is close to the southeast of the Paparoa Mine area, mining access would be most convenient from the west, and the 150,000 tons of indicated coal on its eastern margin are not incorporated in the estimates for the Paparoa area.

摘要:

Epidote amphibolites occurring as accidental blocks in the tuff of the St. Heliers Bay volcano and at Taylor's Hill, Auckland, are described. They are regarded as the product of the retrogressive metamorphism of a gabbroid intrusion into the basement rocks.
