Coromandel Volcanic Zone
The Coromandel Volcanic Zone (CVZ) is an extinct intraplate volcanic arc stretching from Great Barrier Island in the north, through the Coromandel Peninsula, to the Kaimai Range in the south. The area of transition between it and the newer and still active Taupō Volcanic Zone is now usually separated and is called the Tauranga Volcanic Centre. Its volcanic activity was associated with the formation and most active period of the Hauraki Rift. Geology Tectonics The Coromandel Volcanic Zone is generally older than the currently still active Hauraki and Taupō Rifts. This has implications as the widening of the Hauraki Rift was most about 5.5 million years ago, so the Kiwitahi volcanics (called by some the Kiwitahi Volcanic Zone), which occur west of the Coromandel Peninsula and the Hauraki Rift are probably best regarded as related to the Coromandel Volcanic Zone. For example, some of the volcanics are broadly contemporaneous in age, composition and orientation north south, with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Island
The North Island, also officially named Te Ika-a-Māui, is one of the two main islands of New Zealand, separated from the larger but much less populous South Island by the Cook Strait. The island's area is , making it the world's 14th-largest island. The world's 28th-most-populous island, Te Ika-a-Māui has a population of accounting for approximately % of the total residents of New Zealand. Twelve main urban areas (half of them officially cities) are in the North Island. From north to south, they are Whangārei, Auckland, Hamilton, Tauranga, Rotorua, Gisborne, New Plymouth, Napier, Hastings, Whanganui, Palmerston North, and New Zealand's capital city Wellington, which is located at the south-west tip of the island. Naming and usage Although the island has been known as the North Island for many years, in 2009 the New Zealand Geographic Board found that, along with the South Island, the North Island had no official name. After a public consultation, the board officially ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coromandel Range
A true-colour image showing Auckland city (left), the Hauraki Gulf (centre) and the Coromandel Peninsula (right). The scene was acquired by NASA's Terra satellite, on October 23, 2002. The Coromandel Range is a mountain range running the length of the Coromandel Peninsula in the North Island of New Zealand. It is located east of the city of Auckland, and runs north–south for approximately 110 kilometres. It is at a right angle to the Tararua ranges. The highest point in the range is Mount Moehau (892 metres/2927 feet), at the northern end of the peninsula within the Moehau Range. There are numerous peaks over 600 metres in height. In pre-European times, the southern Coromandel Range was densely forested by trees such as kauri, mataī and tawa, and was a home for birds such as kererū, tui, kākā and kiwi. Greywacke from the ranges was a source for many stone tools used by Hauraki Māori. The range is one of several that form a bone running through the northern North Island ...

Tuff
Tuff is a type of rock made of volcanic ash ejected from a vent during a volcanic eruption. Following ejection and deposition, the ash is lithified into a solid rock. Rock that contains greater than 75% ash is considered tuff, while rock containing 25% to 75% ash is described as tuffaceous (for example, ''tuffaceous sandstone''). Tuff composed of sandy volcanic material can be referred to as volcanic sandstone. Tuff is a relatively soft rock, so it has been used for construction since ancient times. Because it is common in Italy, the Romans used it often for construction. The Rapa Nui people used it to make most of the ''moai'' statues on Easter Island. Tuff can be classified as either igneous or sedimentary rock. It is usually studied in the context of igneous petrology, although it is sometimes described using sedimentological terms. Tuff is often erroneously called tufa in guidebooks and in television programmes. Volcanic ash The material that is expelled in a volcanic ...

Mount Hobson (Great Barrier Island)
Mount Hobson ( mi, Hirakimatā) is the highest mountain on Great Barrier Island, New Zealand. Located in the centre of the island, it rises above sea level. Geography Various mountain tracks allow relatively easy access to the summit, with the shortest (2 hour) track leading through the famous Windy Canyon. Great views over the island to the Coromandel Peninsula and the Poor Knights Islands are often possible from the top of the mountain. The summit area is a breeding ground for the black petrel, (from 'Nic's outdoors' on ) and the track in this part is mostly composed of boardwalks and stairs to protect the breeding areas and prevent erosion. A number of rare and declinin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gold
Gold is a chemical element with the symbol Au (from la, aurum) and atomic number 79. This makes it one of the higher atomic number elements that occur naturally. It is a bright, slightly orange-yellow, dense, soft, malleable, and ductile metal in a pure form. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions. Gold often occurs in free elemental ( native state), as nuggets or grains, in rocks, veins, and alluvial deposits. It occurs in a solid solution series with the native element silver (as electrum), naturally alloyed with other metals like copper and palladium, and mineral inclusions such as within pyrite. Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides). Gold is resistant to most acids, though it does dissolve in aqua regia (a mixture of nitric acid and hydrochloric acid), forming a soluble tetrachloroaurate anion. Gold is ...

Te Aroha
Te Aroha ( mi, Te Aroha-a-uta) is a rural town in the Waikato region of New Zealand with a population of 3,906 people in the 2013 census, an increase of 138 people since 2006. It is northeast of Hamilton and south of Thames. It sits at the foot of Mount Te Aroha, the highest point in the Kaimai Range. History The name Te Aroha derives from the Māori name of Mount Te Aroha. In one version, Rāhiri, the eponymous ancestor of Ngāti Rāhiri Tumutumu, climbed the mountain and saw his homeland in the distance and felt a sense of love () for it. The town is properly named ; meaning 'inland', so the town is named "love flowing inland". In some Tainui traditions, Rakataura, a tohunga of the ''Tainui'' waka, was one of the first people to leave the waka, settling at Rarotonga / Mount Smart. After a period of time, Rakataura decided to leave Tāmaki Makaurau and travel south, however during the journey his wife Kahukeke died. Eventually Rakataura settled at Te Aroha, naming the ...

Tairua
The town of Tairua is on the east coast of the Coromandel Peninsula in the North Island of New Zealand. It lies at the mouth of the Tairua River on its north bank and on the small Paku Peninsula. Tairua is a Māori name which translates literally as ''tai'': tides, ''rua'': two.Wises New Zealand Guide, 7th Edition, 1979. p. 412.

Hot Water Beach
Hot Water Beach is a beach on the east coast of the Coromandel Peninsula, New Zealand, just south of Mercury Bay. It is approximately 12 kilometres south east of Whitianga, and approximately 175 kilometres from Auckland by car. Its name comes from underground hot springs that filter up through the sand between the high and low water tidal reaches. The beach is a popular destination both for locals and tourists visiting New Zealand. Annual visitor numbers have been estimated at 700,000, making it one of the most popular geothermal attractions in the Waikato region. Hot water springs Within two hours either side of low tide, it is possible to dig into the sand allowing hot water to escape to the surface forming a hot water pool. The water, with a temperature as hot as 64 °C (147 °F), filters up from two underground fissures located close to each other. These natural springs can be found on the beach opposite the off-shore rocks. Visitors often dig large holes and relax ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mercury Islands
The Mercury Islands are a group of seven islands off the northeast coast of New Zealand's North Island. They are located off the coast of the Coromandel Peninsula, and northeast of the town of Whitianga. History The Ngāti Karaua (a hapu of the Ngāti Whanaunga) and the Ngāti Hei inhabited the islands since the 14th century.
