Ninepin Rock
Te Toka-Tapu-a-Kupe / Ninepin Rock is an island at the mouth of the Manukau Harbour, at Whatipu in the Waitākere Ranges area. Geology The island is a volcanic plug of the Miocene era Waitākere Volcano, composed of stratified rudite and intrusive andesite. The rock is what remains of one of the volcano's funnel-shaped vents on the eastern side of the mountain, which was uplifted from the sea between 3 and 5 million years ago. The island is a volcanic plug of the Miocene era Waitākere Volcano, composed of stratified rudite and intrusive andesite. The rock is what remains of one of the volcano's funnel-shaped vents on the eastern side of the mountain, which was uplifted from the sea 17 million years ago. As the volcano aged and eroded, the vent filled with collapsed lava, scoria and volcanic bombs, until it formed into its modern-day shape. History The traditional name for the rock, Te Toka-Tapu-a-Kupe, refers to the Polynesian navigator Kupe. According to Te Kawerau ā ...

Manukau Harbour
The Manukau Harbour is the second largest natural harbour in New Zealand by area. It is located to the southwest of the Auckland isthmus, and opens out into the Tasman Sea. Geography The harbour mouth is between the northern head ("Burnett Head" / "Ohaka Head") located at the southern end of the Waitākere Ranges and South Head at the end of the Āwhitu Peninsula reaching up from close to the mouth of the Waikato River. The mouth is only 1800 metres wide, but after a nine kilometre channel it opens up into a roughly square basin 20 kilometres in width. The harbour has a water surface area of 394 square kilometres. There is a tidal variation of up to 4 metres, a very substantial change, especially since the harbour, being silted up with almost 10 million years of sedimentation, is rather shallow itself.Manukau Ha ...

Tasman Sea
The Tasman Sea (Māori: ''Te Tai-o-Rēhua'', ) is a marginal sea of the South Pacific Ocean, situated between Australia and New Zealand. It measures about across and about from north to south. The sea was named after the Dutch explorer Abel Janszoon Tasman, who in 1642 was the first known person to cross it. British explorer Lieutenant James Cook later extensively navigated the Tasman Sea in the 1770s during his three voyages of exploration. The Tasman Sea is informally referred to in both Australian and New Zealand English as the Ditch; for example, "crossing the Ditch" means travelling to Australia from New Zealand, or vice versa. The diminutive term "the Ditch" used for the Tasman Sea is comparable to referring to the North Atlantic Ocean as "the Pond". Climate The south of the sea is passed over by depressions going from west to east. The northern limit of these westerly winds is near to 40°S. During the southern winter, from April to October, the northern branch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Whatipu
Whatipu is a remote beach on the west coast of the Auckland Region in the North Island of New Zealand. The Whatipu area has been managed as a scientific reserve by the Auckland Regional Council since 2002. The road to it is unsealed. To the south of Whatipu is Manukau Harbour. To the north is Karekare. Whatipu is located at the southern end of the Waitākere Ranges. Shifting sands have substantially changed the beach since the 1940s. Over 6 square kilometres has been added to the beach since then. Geography Between 3 and 5 million years ago, tectonic forces between the Pacific Plate and Australian Plate uplifted the Waitākere Ranges and subsided the Manukau Harbour. Major features of Whatipu include Te Toka-Tapu-a-Kupe / Ninepin Rock and Paratutae Island, which are remnants of the Miocene era Waitākere Volcano. From the 1930s to the 1960s, sandy material began accumulating at Whatipu, creating a 1.5km strip of sand, where plants and fresh water swamps developed. Much of t ...

Waitākere Ranges
The Waitākere Ranges is a mountain range in New Zealand. Located in West Auckland between metropolitan Auckland and the Tasman Sea, the ranges and its foothills and coasts comprise some of public and private land. The area, traditionally known to Māori as ''Te Wao Nui o Tiriwa'' (The Great Forest of Tiriwa), is of local, regional, and national significance. The Waitākere Ranges includes a chain of hills in the Auckland Region, generally running approximately from north to south, 25 km west of central Auckland. The ranges are part of the Waitākere Ranges Regional Park. From 1 May 2018 the forested areas of the Waitākere Ranges Regional Park were closed, with some exceptions, while Auckland Council upgraded the tracks to dry foot standard protect the roots and to prevent the spread of kauri dieback, bacteria that affect kauri trees and prevents them from getting nutrients, effectively killing them. There is no cure. But Etymology The name ''Wai-tākere'' origina ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcanic Plug
A volcanic plug, also called a volcanic neck or lava neck, is a volcanic object created when magma hardens within a vent on an active volcano. When present, a plug can cause an extreme build-up of high gas pressure if rising volatile-charged magma is trapped beneath it, and this can sometimes lead to an explosive eruption. In a plinian eruption the plug is destroyed and ash is ejected. Glacial erosion can lead to exposure of the plug on one side, while a long slope of material remains on the opposite side. Such landforms are called crag and tail. If a plug is preserved, erosion may remove the surrounding rock while the erosion-resistant plug remains, producing a distinctive upstanding landform. Examples of volcanic plugs Africa Near the village of Rhumsiki in the Far North Province of Cameroon, Kapsiki Peak is an example of a volcanic plug and is one of the most photographed parts of the Mandara Mountains. Spectacular volcanic plugs are present in the center of La Gomer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miocene
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia. During the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rudite
Rudite is a general name used for a sedimentary rock composed of rounded or angular detrital grains, i.e. granules, pebbles, cobbles, and boulders, which are coarser than sand in size. Rudites include sedimentary rocks composed of both siliciclastic, i.e. conglomerate and breccia, and carbonate grains, i.e. calcirudite and rudstone. This term is equivalent to the Greek-derived term, psephite. Rudite was initially proposed by GrabauGrabau, A.W. (1904) ''On the classification of sedimentary rocks.'' American Geologist. vol. 33, pp. 228-247. as "rudyte." It is derived from the Latin word ''rudus'' for "crushed stone," "rubbish," "debris," and "rubble".U.S. Bureau of Mines Staff (1996) ''Dictionary of Mining, Mineral, & Related Terms.''

Andesite
Andesite () is a volcanic rock of intermediate composition. In a general sense, it is the intermediate type between silica-poor basalt and silica-rich rhyolite. It is fine-grained (aphanitic) to porphyritic in texture, and is composed predominantly of sodium-rich plagioclase plus pyroxene or hornblende. Andesite is the extrusive equivalent of plutonic diorite. Characteristic of subduction zones, andesite represents the dominant rock type in island arcs. The average composition of the continental crust is andesitic. Along with basalts, andesites are a component of the Martian crust. The name ''andesite'' is derived from the Andes mountain range, where this rock type is found in abundance. It was first applied by Christian Leopold von Buch in 1826. Description Andesite is an aphanitic (fine-grained) igneous rock that is intermediate in its content of silica and low in alkali metals. It has less than 20% quartz and 10% feldspathoid by volume, with at least 65% of the fe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kupe
Kupe ( ~1180-1320) was a legendary Polynesian explorer, navigator and great rangatira of Hawaiki, who is said to have been the first human to discover New Zealand. Whether Kupe existed historically is likely but difficult to confirm. He is generally held to have been born to a father from Rarotonga and a mother from Raiatea, and probably spoke a proto-Māori language similar to Cook Islands Māori or Tahitian. His voyage to New Zealand would ensure that the land would be known to the Polynesians, and he would therefore be responsible for the genesis of Māori civilisation. Kupe features prominently in the mythology and oral history of some Māori iwi (tribes), but the details of his life differ between iwi. Various legends and histories describe Kupe's extensive involvement in the settlement of Aotearoa, around 1000–1300 CE, with many talking of his achievements, such as the hunting and destruction of the great octopus, Te Wheke-a-Muturangi.

Te Kawerau ā Maki
Te Kawerau ā Maki, Te Kawerau a Maki, or Te Kawerau-a-Maki is a Māori ''iwi'' (tribe) of the Auckland Region of New Zealand. It had 251 registered adult members as of June 2017. Auckland Council gave it land for a marae at Te Henga (Bethells Beach) in 2018; it has no ''wharenui'' (meeting house) yet. History Te Kawerau ā Maki are the descendants of the ''rangatira'' (chief) Maki and his wife Rotu, who migrated with their family and followers from Kawhia to Tāmaki Makaurau (Auckland) in the early 1600s. Te Kawerau trace their ancestry from a number of Māori migration canoes, particularly the Tainui, but also Aotea, Tokomaru, Kahuitara and Kurahaupō. Tainui ancestors including Hoturoa and the tohunga Rakataura (Hape) are particularly important in Te Kawerau whakapapa, as is the ancient turehu ancestor and tohunga Tiriwa. Maki and his people were related to a number of groups who had occupied the Auckland region since the fourteenth century, including the Tainui ''hapū'' ...

Karakia
Karakia are Māori incantations and prayers, used to invoke spiritual guidance and protection. With the nineteenth-century introduction of Christianity to New Zealand, Māori adopted (or wrote new) karakia to acknowledge the new faith. Modern karakia tend to contain a blend of Christian and traditional influence, and their poetic language may make literal translations into English not always possible.Karakia , Otago University website. Retrieved 23 July 2019. In modern Māori society, performances of ''karakia'' frequently open important meetings and ceremonies, both within a Māori context (such as tribal , [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
