Hurupaki Mountain
Hurupaki Mountain is in Kamo, Whangārei, New Zealand. The centre of Hurupaki Mountain lies between Three Mile Bush Road and Dip Road, approximately 1.5 kilometres west of Kamo township. Hurupaki Mountain is visible from State Highway 1. Characteristics Hurupaki Mountain is a high scoria cone whose associated basalt lava has been dated at 310,000 years old. It is part of the Puhipuhi-Whangarei volcanic field. This volcanic area is similar to the Auckland volcanic field in that it has formed over a type of hot spot in the mantle, i.e. not at a current plate boundary. The Whangārei field is older than the Auckland field, and Hurupaki is probably one of the younger centres. There is another basaltic field in Northland Northland may refer to: Corporations * Northland Organic Foods Corporation, headquartered in Saint Paul, Minnesota * Northland Resources, a mining business * Northland Communications, an American cable television, telephone and internet service ...

Whangārei Volcanic Field
The Whangārei volcanic field (Puhipuhi-Whangarei volcanic field) is an area of intra-plate monogenetic volcanism located near the city of Whangārei, North Island, New Zealand. It was last active between 260,000 to 319,000 years ago and continues to be potentially active as a low-velocity seismic zone in the crust exists beneath Whangārei, which is interpreted to be a body of partial melt. This mantle source has been coupled to the lithosphere for about 8 million years. As the field has potentially been active at low frequency for millions of years, with 100,000 years or more between events it might best be regarded as dormant. The recent vents active in the last million years include some dacite in composition. Composition details are freely available for most of the field but many vents do not have ages.

New Zealand State Highway 1
State Highway 1 (SH 1) is the longest and most significant road in the New Zealand road network, running the length of both main islands. It appears on road maps as SH 1 and on road signs as a white number 1 on a red shield, but it has the official designations SH 1N in the North Island, SH 1S in the South Island. SH 1 is long, in the North Island and in the South Island. Since 2010 new roads have reduced the length from . For the majority of its length it is a two-lane single carriageway, with at-grade intersections and property accesses, in both rural and urban areas. These sections have some passing lanes. Around of SH 1 is of motorway or expressway standard : in the North Island and in the South Island. Route North Island (SH 1N) SH 1 starts at Cape Reinga, at the northwestern tip of the Aupouri Peninsula, and since April 2010 has been sealed (mainly with either chipseal or asphalt) for its entire length. From Waitiki Landing south of Cape Reinga, SH 1 trav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tree Plantation
A tree plantation, forest plantation, plantation forest, timber plantation or tree farm is a forest planted for high volume production of wood, usually by planting one type of tree as a monoculture forest. The term ''tree farm'' also is used to refer to tree nurseries and Christmas tree farms. Plantation forestry can produce a high volume of wood in a short period of time. Plantations are grown by state forestry authorities (for example, the Forestry Commission in Britain) and/or the paper and wood industries and other private landowners (such as Weyerhaeuser, Rayonier and Sierra Pacific Industries in the United States or Asia Pulp & Paper in Indonesia). Christmas trees are often grown on plantations, and in southern and southeastern Asia, teak plantations have recently replaced the natural forest. Industrial plantations are actively managed for the commercial production of forest products. Industrial plantations are usually large-scale. Individual blocks are usually even-aged ...

Pā (Māori)
The word pā (; often spelled pa in English) can refer to any Māori village or defensive settlement, but often refers to hillforts – fortified settlements with palisades and defensive terraces – and also to fortified villages. Pā sites occur mainly in the North Island of New Zealand, north of Lake Taupō. Over 5,000 sites have been located, photographed and examined, although few have been subject to detailed analysis. No pā have been yet located from the early colonization period when early Polynesian-Māori colonizers lived in the lower South Island. Variations similar to pā occur throughout central Polynesia, in the islands of Fiji, Tonga and the Marquesas Islands. In Māori culture, a great pā represented the mana (prestige or power) and strategic ability of an iwi (tribe or tribal confederacy), as personified by a rangatira (chieftain). Māori built pā in various defensible locations around the territory (rohe) of an iwi to protect fertile plantation-sites and ...

Scenic Reserves Of New Zealand
Scenic reserves are a type of Protected areas of New Zealand, New Zealand protected area. They are the most common, and probably most widespread, form of protected area in the country. The reserve vary size: while most are less than 100 hectares, some are more than 1,000 hectares. Some are "islands of unspoilt nature in a sea of farmland". Scenic reserves were first created when communities decided to keep some original vegetation in an area where most original vegetation had been removed. Most are patches of bush, often close to roads. Statutory control of scenic reserves was covered by the Scenery Preservation Act 1903 until the passing of the Reserves Act 1977. Ball’s Clearing Scenic Reserve in Hawke’s Bay, an area of native forest fenced off from the surrounding pasture land, is typical scenic reserve. North Island The following scenic reserves are located in and around the North Island: Northland * Aponga Settlement Scenic Reserve * Aputerewa Scenic Reserve * Arapaoa R ...

Kaikohe-Bay Of Islands Volcanic Field
The recently active basaltic Kaikohe-Bay of Islands volcanic field in the Northland Region of New Zealand is associated geographically with an older region of extinct volcanism to its north the Wairakau Volcanic Centre, meaning eruptions in this region have occurred over the last 20 million years. All the cones older than 2 million years have eroded away, leaving plateaus from Ōkaihau to Kerikeri and north to Whangaroa from the old andesite/dacite stratovolcanoes of the Wairakau Volcanic Centre and the ten million year old or more recent volcanoes in field towards the south. In the southern part of the field, around 12 small basaltic scoria cones, and a rhyolite dome erupted in the last 500,000 years around Kaikohe. The field is considered dormant, rather than extinct. Tectonics The field is part of the eastern Northland volcanic belt which extends south to the Whangārei volcanic field near Whangarei and the south east volcanics of the Taurikura volcanic complex as found in t ...

Northland Region
The Northland Region ( mi, Te Tai Tokerau) is the northernmost of New Zealand's 16 local government regions. New Zealanders sometimes refer to it as the Winterless North because of its mild climate all throughout the year. The main 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 census, placing it as the fastest growing region in New Zealand, ahead of other strong growth regions such as the Bay of Plenty (2nd with 15%) and Waikato (3rd with 13.5%). Geography The Northland Region occupies the northern 80% (265 km) of the 330 km Northland Peninsula, the southernmost part of which is in the Auckland Region. Stretching from a line at which the peninsula narrows to a width of just 15 km a little north of the town of Wellsford, Northland Region extends north to the tip of the Northland Peninsula, covering an area of 13,940&nb ...

Auckland Volcanic Field
The Auckland volcanic field is an area of monogenetic volcanoes covered by much of the metropolitan area of Auckland, New Zealand's largest city, located in the North Island. The approximately 53 volcanoes in the field have produced a diverse array of maars (explosion craters), tuff rings, scoria cones, and lava flows. With the exception of Rangitoto, no volcano has erupted more than once, but the other eruptions lasted for various periods ranging from a few weeks to several years. Rangitoto erupted several times and recently twice; in an eruption that occurred about 600 years ago, followed by a second eruption approximately 50 years later. The field is fuelled entirely by basaltic magma, unlike the explosive subduction-driven volcanism in the central North Island, such as at Mount Ruapehu and Lake Taupō.Ian E.M. Smith and Sharon R.

Whangārei
Whangārei () is the northernmost city in New Zealand and the regional capital of Northland Region. It is part of the Whangarei District, Whangārei District, a local body created in 1989 from the former Whangārei City, Whangārei County and Hikurangi Town councils, to administer both the city proper and its hinterland. The city population was estimated to be an increase from 47,000 in 2001. The wider Whangarei District had a population of Etymology The origin of the name Whangārei is unclear, as a number of pūrākau (traditional stories) are associated with the harbour. One major tradition involves the sisters Reitū and Reipae of the ''Tainui (canoe), Tainui'' migratory waka, who either flew from the Waikato north on the backs of birds, or in the form of birds. Other traditions describe the meaning of Whangārei as "lying in wait to ambush", referring to warriors watching over the harbour from Te Tihi-o-Kahukura / Castle Rock, or Whangārei meaning "to gather", referri ...

Basalt
Basalt (; ) is an aphanite, aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the planetary surface, surface of a terrestrial planet, rocky planet or natural satellite, moon. More than 90% of all volcanic rock on Earth is basalt. Rapid-cooling, fine-grained basalt is chemically equivalent to slow-cooling, coarse-grained gabbro. The eruption of basalt lava is observed by geologists at about 20 volcanoes per year. Basalt is also an important rock type on other planetary bodies in the Solar System. For example, the bulk of the plains of volcanism on Venus, Venus, which cover ~80% of the surface, are basaltic; the lunar mare, lunar maria are plains of flood-basaltic lava flows; and basalt is a common rock on the surface of Mars. Molten basalt lava has a low viscosity due to its relatively low silica content (between 45% and 52%), resulting in rapidly moving lava flo ...

Kamo, New Zealand
Kamo is a suburb in Northern Whangārei. approximately five minutes drive from the Whangārei CBD. The name comes from a Māori word meaning "eyelash", but has also been said to mean "to bubble up", referring to hot springs in the area. Mount Parakiore is a volcanic dome rising 391 m to the northwest of the town. It is about one million years old, and part of the Harbour Fault which also includes Mount Hikurangi near Hikurangi, and Parihaka in Whangārei. History Coal mining was an early industry in the area. Tunnelling first started in 1875, but it was not practical to carry the coal over the unmetalled roads to Whangārei wharf. In 1882 a short railway line was completed between Kamo and Whangārei to carry the coal. This was one of Northland's first railways. The railway still exists as part of the North Auckland Line. The mine closed in 1955, with the seams worked out. Limonite was also quarried at Kamo. A Wesleyan church was built in 1881, the Anglican All Saints Church ...

Intrusive Rock
Intrusive rock is formed when magma penetrates existing rock, crystallizes, and solidifies underground to form ''Igneous intrusion, intrusions'', such as batholiths, dike (geology), dikes, Sill (geology), sills, laccoliths, and volcanic necks.Intrusive RocksIntrusive rocks accessdate: March 27, 2017.Igneous intrusive rocks, accessdate: March 27, 2017.Britannica.comintrusive rock , geology , Britannica.com accessdate: March 27, 2017. Intrusion is one of the two ways igneous rock can form. The other is extrusive rock, extrusion, such as a Types of volcanic eruptions, volcanic eruption or similar event. An intrusion is any body of intrusive igneous rock, formed from magma that cools and solidifies within the crust of the planet. In contrast, an ''extrusion'' consists of extrusive rock, formed above the surface of the crust. Some geologists use the term plutonic rock synonymously with intrusive rock, but other geologists subdivide intrusive rock, by crystal size, into coarse-grai ...
