Geology Of The Auckland Region
The Auckland region of New Zealand is built on a basement of greywacke rocks that form many of the islands in the Hauraki Gulf, the Hunua Ranges, and land south of Port Waikato. The Waitākere Ranges in the west are the remains of a large andesitic volcano, and Great Barrier Island was formed by the northern end of the Coromandel Volcanic Zone. The Auckland isthmus and North Shore, New Zealand, North Shore are composed of Waitemata sandstone and mudstone, and portions of the Northland Allochthon extend as far south as Albany, New Zealand, Albany. Little Barrier Island was formed by a relatively isolated andesitic volcano, active around 1 to 3 million years ago. The Manukau Harbour, Manukau and South Kaipara Harbours are protected by the recent sand dune deposits of the Āwhitu and South Kaipara Peninsulas. Recent basaltic volcanic activity has produced many volcanic cones throughout the Auckland region, including the iconic and youngest volcano Rangitoto Island. Basement rocks As ...

Dun Mountain–Maitai Terrane
The Dun Mountain–Maitai terrane comprises the Dun Mountain ophiolite belt (also called the mineral belt), Maitai group, and Patuki mélange. The Dun Mountain Ophiolite is an ophiolite of Permian age located in New Zealand's South Island. Prehistorically this ophiolite was quarried by Māori for both metasomatized argillite and pounamu (jade) which was used in the production of tools and jewellery. In the late 1800s, the Dun Mountain ophiolite belt was surveyed for its economic potential. During this time the rock types dunite and rodingite (after Dun Mountain and the Roding River) were first named. Discovery of economic deposits of chromite near Nelson lead to the building of New Zealand’s first railway, however, extraction only occurred between 1862 and 1866. In the 20th century, serpentinite was mined for fertiliser and the ophiolite remains one of New Zealand's main sources of pounamu (jade), but all other mineral exploration has failed to find economic deposits.

King Country
The King Country ( Māori: ''Te Rohe Pōtae'' or ''Rohe Pōtae o Maniapoto'') is a region of the western North Island of New Zealand. It extends approximately from Kawhia Harbour and the town of Ōtorohanga in the north to the upper reaches of the Whanganui River in the south, and from the Hauhungaroa and Rangitoto Ranges in the east to near the Tasman Sea in the west. It comprises hill country, large parts of which are forested. The region, albeit loosely defined, is very significant in New Zealand's history. The term "King Country" dates from the New Zealand Wars of the 1860s, when colonial forces invaded the Waikato and forces of the Māori King Movement withdrew south of what was called the ''aukati'', or boundary, a line of ''pā'' alongside the Puniu River near Kihikihi. Land behind the ''aukati'' remained native territory, with Europeans warned they crossed it under threat of death. Known for its rugged, rural roads and diverse landscape, the King Country has a warm c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waikato
The Waikato () is a region of the upper North Island of New Zealand. It covers the Waikato District, Waipā District, Matamata-Piako District, South Waikato District and Hamilton City, as well as Hauraki, Coromandel Peninsula, the northern King Country, much of the Taupō District, and parts of the Rotorua Lakes District. It is governed by the Waikato Regional Council. The Waikato stretches from Coromandel Peninsula in the north, to the north-eastern slopes of Mount Ruapehu in the south, and spans the North Island from the west coast, through the Waikato and Hauraki to Coromandel Peninsula on the east coast. Broadly, the extent of the region is the Waikato River catchment. Other major catchments are those of the Waihou, Piako, Awakino and Mōkau rivers. The region is bounded by Auckland on the north, Bay of Plenty on the east, Hawke's Bay on the south-east, and Manawatū-Whanganui and Taranaki on the south. Waikato Region is the fourth largest region in the c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northland Region
Northland (), officially the Northland Region, is the northernmost of New Zealand's 16 regions of New Zealand, local government regions. New Zealanders sometimes refer to it as the Winterless North because of its mild climate all throughout the year. The major population centre is the city of Whangārei, and the largest town is Kerikeri. At the 2018 New Zealand census, Northland recorded a population growth spurt of 18.1% since the previous 2013 New Zealand census, 2013 census, placing it as the fastest growing region in New Zealand, ahead of other strong growth regions such as the Bay of Plenty Region (2nd with 15%) and Waikato (3rd with 13.5%). Geography The Northland Region occupies the northern 80% () of the Northland Peninsula, the southernmost part of which is in the Auckland region. It is bounded to the west by the Tasman Sea, and to the east by the Pacific Ocean. The land is predominantly rolling hill country. Farming and forestry occupy over half of the land and are ...

Coromandel Peninsula
The Coromandel Peninsula () on the North Island of New Zealand extends north from the western end of the Bay of Plenty, forming a natural barrier protecting the Hauraki Gulf and the Firth of Thames in the west from the Pacific Ocean to the east. It is wide at its broadest point. Almost its entire population lives on the narrow coastal strips fronting the Hauraki Gulf and the Bay of Plenty. In clear weather the peninsula is clearly visible from Auckland, the country's biggest city, which lies on the far shore of the Hauraki Gulf, to the west. The peninsula is part of the Thames-Coromandel District and the Waikato Region. Names The Māori name for the peninsula is ''Te Tara-o-te-Ika-a-Māui'', meaning "the barb of Māui's fish". This comes from the legend of Māui and the Fish, in which the demigod uses his hook to catch a great fish (Te Ika-a-Māui or the North Island) from the depths of the Pacific Ocean. In Hauraki Māori tradition, the fish is likened to a sti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Argillite
Argillite () is a fine-grained sedimentary rock composed predominantly of Friability, indurated clay particles. Argillaceous rocks are basically lithified muds and Pelagic sediment, oozes. They contain variable amounts of silt-sized particles. The argillites grade into shale when the Fissility (geology), fissile layering typical of shale is developed. Another name for poorly lithified argillites is ''mudstone''. These rocks, although variable in composition, are typically high in aluminium and silica with variable alkali and alkaline earth cations. The term pelite, ''pelitic'' or ''pelite'' is often applied to these sediments and rocks. Metamorphism of argillites produces slate, phyllite, and pelitic schist. Belt Supergroup The Belt Supergroup, an assemblage of rocks of late Precambrian (Mesoproterozoic) age, includes thick sequences of argillite, as well as other metamorphosed or semi-metamorphosed mudstones.Schieber, J. 1990.

Chert
Chert () is a hard, fine-grained sedimentary rock composed of microcrystalline or cryptocrystalline quartz, the mineral form of silicon dioxide (SiO2). Chert is characteristically of biological origin, but may also occur inorganically as a precipitation (chemistry), chemical precipitate or a diagenesis, diagenetic replacement, as in petrified wood. Chert is typically composed of the petrified remains of siliceous ooze, the biogenic sediment that covers large areas of the deep ocean floor, and which contains the silicon skeletal remains of diatoms, Dictyochales, silicoflagellates, and radiolarians. Precambrian cherts are notable for the presence of fossil cyanobacteria. In addition to Micropaleontology, microfossils, chert occasionally contains macrofossils. However, some chert is devoid of any fossils. Chert varies greatly in color, from white to black, but is most often found as gray, brown, grayish brown and light green to rusty redW.L. Roberts, T.J.

Kawau
Kawau Island is in the Hauraki Gulf, close to the north-eastern coast of the North Island of New Zealand. It is named after the Māori word for the shag.At its closest point it lies off the coast of the Northland Peninsula, just south of Tāwharanui Peninsula, and about by sea journey from Sandspit Wharf, and shelters Kawau Bay to the north-east of Warkworth. It is north of Auckland. Almost every property on the island relies on direct access to the sea. There are only two short roads serving settlements at Schoolhouse Bay and South Cove, and most residents have private wharves for access to their front door steps. A regular ferry service operates to the island from Sandspit Wharf on the mainland, as do water taxi services. Mansion House, in the Kawau Island Historic Reserve, is an important historic tourist attraction. Geography The island is at its longest axes, and is almost bisected by the long inlet of Bon Accord Harbour, which is geologically a "drowned valley" ...
