摘要:

Two additional species of Rhizangiid corals are recorded from the Wanganui Basin.Culicia rubeola(Quoy and Gaimard) is also represented in the modern fauna and is discussed in relation to depth distribution of the Wanganui faunas and possible occurrence of derived coral specimens in the Cook Strait area. Oulangia radames n. sp. is reported for the first time from New Zealand. Its appearance in Tongaporutuan sediments is the earliest record of the genus. Some aspects of the ecology of its occurrence are discussed.

摘要:

The marine, Castlecliffian sedimentation in Central Hawke's Bay is limited to an area between Napier Hill and Black Reef, the fossiliferous sediments having reached a thickness of at least 1,200 ft. The deposition of these sediments has been typically paralic, and indicates that terrestrial and marine conditions alternated in the basin. The downward movement in the basin must have been the result of rather fierce tectonic disturbances, which are now attributed to the southward movements of the New Zealand Overthrust. As the overthrust progressed such stretching developed, that the area between Napier and Cape Kidnappers was literally torn apart. The faulted depression that thus formed was filled with sediments to form the Castlecliffian sequence.

摘要:

Plant microfossil samples from drillholes near Frankton, through some 700 ft of pumiceous and non-pumiceous sand, silt, clay and lignitic beds, range in age from Waitotaran (Upper Pliocene) to Upper Pleistocene or younger. The Plio-Pleistocene (Waitotaran-Nukumaruan) boundary is clearly shown where a sub-tropical Waitotaran vegetation is replaced by a Lower Nukumaruan vegetation, indicating a climate cooler than that of the present day. A brief comparison is made with similar Plio-Pleistocene sequences elsewhere in New Zealand.

摘要:

Thirteen new analyses of lavas from Auckland are presented and discussed. The rocks are shown to be olivine-rich alkaline basalts, chemically comparable with lavas from the Pacific basin but possibly derived by crystallisation fractionation along a trend characteristic of a continental environment. The composition of the Auckland rocks is compared with that of Pliocene-Pleistocene basalts from Northland and from South Auckland. The origin of olivine nodules and a nepheline basanite associated with the Auckland basalts is considered.

摘要:

Between 1947 and 1955 the Department of Scientific and Industrial Research established the New Zealand Primary Gravity Network, a set of 437 control points for gravity observations in the North and South Islands of New Zealand. The gravity differences between nineteen stations were measured with the Cambridge pendulum apparatus, and between all stations with a North American gravity meter. Initially the network observations were reduced separately in the North and South Islands; the resulting gravity values constitute the New Zealand Provisional System, which has remained the basis for recording gravity results within New Zealand. Subsequent adjustment of the network, both to make it internally consistent and to bring it into agreement with the first order world network based on Potsdam, has resulted in a revised set of values of gravity, which constitute the New Zealand Potsdam System (1959), and which differ by an average of + 5·0 mgal from the New Zealand Provisional System values. Values of gravity and of free air and Bouguer anomalies are given for the 437 network stations.

摘要:

This note stresses certain aspects of earlier work in the Alpine schists of New Zealand, particularly the abundance of mesoscopic folds and the diversity of relations of schistosity planes to relict stratification planes.

摘要:

Kalentera marwickin. sp. is figured and described. The holotype and other specimens are from beds of the Otapirian Stage (Rhaetian) near Awakino, south-west Auckland, and a number of specimens that seem conspecific are recorded from beds of the same age further north near Marakopa and Kawhia as well as in the Kaihiku Range, while the species is found together withMonotis calrataof the Warepan Stage (Norian) near Marakopa. The form appears to be morphologically as well as stratigraphically intermediate between the Aratauran (Hettangian-Sinemurian) genotypeK. mackayiMarwick and the Otamitan (upper Carnian)Triapborus zealandicus(Trechmann) from which it probably developed. It is postulated that members of the family formed part of the vagrant benthos in or on a shallow silty relatively flat sea-floor.

摘要:

The aquifers and aquicludes of the Christchurch Artesian System are moderately-tohighly incompetent and elastic, judged by the effects of ocean tides, of the changing water levels of Lake Ellesmere, and of earthquakes and passing heavy vehicles upon water levels in wells tapping them. The “outcrop” hypothesis advanced by Speight (1911) to account for the tidal effect is rejected in favour of one of loading.

摘要:

Analyses of some New Zealand ground waters are examined in relation to the origin of their boron. In the Waikato district only warm ground waters are significantly enriched in boron. These probably derive most of their heat and some of their salt content from volcanic sources.
