摘要:

Belemnopsis annae, Belemnopsis maccrawi, and Belemnopsis keariare characteristic taxa of the Heterian stratotype at Kawhia Harbour, New Zealand. When morphological criteria are used, their recognition elsewhere can be difficult. Contrasts in body form are slight, and when collections consist of fragmentary specimens or of juveniles there is a strong possibility of misidentification. Statistical procedures based on apical line positions and on cross sectional shape provide a simple method of recognition. Supporting stratigraphic evidence is available. The succession of taxa present in the Heterian stratotype can be recognised in the Port Waikato region, and two of them are shown to be widely distributed in south–west Auckland.

摘要:

Trough Lake has a permanent cover of floating ice. Contact of the ice with the Koettlitz Glacier produces pressure ridges which are modified by differential ablation. The estimated ablation rate of 300–450 mm of ice per year is higher than that at Lake Miers, 20 km north, due to the increased prevalence of katabatic winds at Trough Lake.

摘要:

Low-grade greywacke of the Torlesse rocks (Canterbury Suite) at the southern end of Otira Gorge contains the Oretian-Warepan indicatorHokonuia limaeformisTrechmann, and other fossil localities suggest a simple southward younging of faunal zones between the Zig Zag (Otira Gorge) and Temple Basin. However, the sequence is structurally complex, with generally steep dips; an apparent large, south-closing shallowly south-west-plunging antiform crops out in the west, and a major, steeply plunging, northward-closing fold occurs in the east. A broad fault zone trends north through the Otira Gorge, and several other extensive faults trend north-east.

摘要:

Recently obtained radiocarbon dates suggest that Maori occupation of coastal areas near Aotea and Kawhia Harbours initiated eolian erosion of previously stable dune systems during the last 600–800 years. This erosion led to the formation of the most recent sand dunes.
