This thesis combines the results of field work, petrographic studies and mineralogical and geochemical data from plutonic rocks of the southern part of the Longwood Complex, Southland, New Zealand. Data presented here ...

Koettlitz Group rocks and intercalated orthogneisses in the mid Taylor Valley and Ferrar Glacier regions form a 1-4km wide, north-northwest trending belt, intruded by a variety of undeformed granitoid pIutons along either ...

Carboniferous to Lower Cretaceous Torlesse rocks and Haast Schist derivatives constitute the major part of the ''eugeosynclinal" facies of the Eastern Province of New Zealand. Strata consist largely of quartzofeldspathic ...

Ata is the most southerly island in a chain of young volcanic islands in the Tonga Group lying to the west of the Tonga trench. It is presently inactive and now consists of a small remnant (1.8 km2) of a large composite ...

This report describes the glacigenic stratigraphy from the Upper Clutha Valley in Central Otago. The deposits from seven glacial advances are described and modelled on a wet based glacier. Stratigraphic classification of ...

The mineralogy and structure of two gabbronorite intrusions forming Bluff Hill, is described. They intrude volcanogenic metasediments of the Greenhills Group and together comprise a segment of Brook Street terrane (Coombs ...

A geological map of the Dusky Sound area (~ 700 km2) is presented at a scale of 1:59 000. The North and South Dusky areas are of generally contrasting character and are described separately. North Dusky is dominated by ...

Wall clays and vein silicates from the fossil hydrothermal system at Mahakirau, Coromandel Peninsula are shown to consist of discrete mineral assemblages. Those in quartz veins are: - K-feldspar - K-mica - kaolinite K-feldspar ...
