Newton River (Fiordland)
The Newton River is a river in Fiordland, New Zealand. It drains Lake Fraser south-westward into the Tasman Sea just south of West Cape. Newton River is an official name, gazetted on 4 February 1960, after being in use by local fishermen for some time. It is about long. The river flows over the Newton River pluton of Carbonferous biotite, granodiorite and granite, which has been glaciated and also forms a rock arch to the south of the river mouth, where a marine terrace has been uplifted within the last half a million years. The beech forest in the valley includes black beech (tawairauriki), kāmahi, and silver beech (tawhai).

West Cape
West Cape is the westernmost point in the main chain of islands of New Zealand. It is located in the far southwest of the South Island, within Fiordland National Park, between Tamatea / Dusky Sound and Taiari / Chalky Inlet. The cape consists of a small rocky shore and low forest-covered sloping land, and is located just north of the Newton River mouth. West Cape is one of the 4 New Zealand Cardinal Capes, as named by Captain James Cook James Cook (7 November 1728 Old Style date: 27 October – 14 February 1779) was a British explorer, navigator, cartographer, and captain in the British Royal Navy, famous for his three voyages between 1768 and 1779 in the Pacific Ocean an ..., on his first voyage to the region in 1769-70. Chart Of New Zealand - J Cook 1769-7 Retrieved on 7 Dec 2017. The other Cardinal Capes named at the time are North Cape (Otou), North Cape, Cape East, and Cape South.

Granite
Granite () is a coarse-grained (phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or ''granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) contain almost no dark minerals. Granite is nearly alway ...

Nothofagus Menziesii
''Nothofagus menziesii'', commonly known as silver beech ( mi, tawhai, tahina), is a tree of the southern beech family endemic to New Zealand. Its common name probably comes from the fact that its bark is whitish in colour, particularly in younger specimens.John Dawson and Rob Lucas "''The Nature Guide to the New Zealand Forest''", Godwit, 2000 It is found from Thames southwards in the North Island (except Mount Taranaki/Egmont),H.H. Allan, "''Flora of New Zealand,volume 1''",Government Printer, 1961 and throughout the South Island. Silver beech is a forest tree up to 30 m tall. The trunk, which is often buttressed, may be up to 2 m in diameter. J. T. Salmon, "''A Field Guide to the Native Trees of New Zealand''", Reed Methuen, 1986 The leaves are small, thick and almost round in shape, 6 to 15 mm long and 5 to 15 mm wide with rounded teeth which usually occur in pairs, 1 or 2 hair fringed domatia are found on the underside of each leaf. Its Māori name is tawhai. It gro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weinmannia Racemosa
''Weinmannia racemosa'', commonly called kāmahi, is an evergreen small shrub to medium-sized tree of the family Cunoniaceae. It is the most abundant forest tree in New Zealand, occurring in lowland, montane, and subalpine forests and shrubland from the central North Island south to Stewart Island. Description Kāmahi bears racemes of small, pink or white flowers from July to January. Fruits are small capsules, long, ripening from October to May. Kāmahi generally occurs with other broadleaf trees, at times acting as a pioneer species which is eventually succeeded by the southern beeches (''Nothofagus'' spp.) or podocarps. It reaches or more in the Catlins of the south-eastern South Island. In forests to the west of the Southern Alps it codominates with southern rātā (''Metrosideros umbellata'') and black beech (''N. solandri''). A closely related tree, tōwai or tawhero ('' W. sylvicola''), replaces kāmahi in the North Island north of latitude 38°S. Uses The bark is ...

Nothofagus Solandri
''Nothofagus solandri'' var. ''solandri'', commonly called black beech, is a variety of the tree species ''Nothofagus solandri'', endemic to New Zealand. Black beech occurs on both the North and the South Island at low altitudes up to the mountains. The other variety of ''N. solandri'' is called mountain beech or ''Nothofagus solandri'' var. ''cliffortioides'', and grows at higher altitudes than black beech. In New Zealand the taxon is called ''Fuscospora solandri''. Black beech is a medium-sized evergreen tree growing to 27 m tall. The leaves are oppositely arranged, ovoid, 10 mm long and 5 mm broad, with smooth margins. Black beech is known as black beech because it is prone to a sooty mold which covers the trunk and branches. This, in turn, is the result of a scale insect which sucks sap from the tree, and excretes honeydew, a sweet liquid, in small droplets (less than 1 mm diameter) on the end of stalks. This feeds the sooty mold, and also forms a valuable ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Natural Arch
A natural arch, natural bridge, or (less commonly) rock arch is a natural landform where an arch has formed with an opening underneath. Natural arches commonly form where inland cliffs, coastal cliffs, fins or stacks are subject to erosion from the sea, rivers or weathering ( subaerial processes). Most natural arches are formed from narrow fins and sea stacks composed of sandstone or limestone with steep, often vertical, cliff faces. The formations become narrower due to erosion over geologic time scales. The softer rock stratum erodes away creating rock shelters, or alcoves, on opposite sides of the formation beneath the relatively harder stratum, or caprock, above it. The alcoves erode further into the formation eventually meeting underneath the harder caprock layer, thus creating an arch. The erosional processes exploit weaknesses in the softer rock layers making cracks larger and removing material more quickly than the caprock; however, the caprock itself continues to er ...

Glacier
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its Ablation#Glaciology, ablation over many years, often Century, centuries. It acquires distinguishing features, such as Crevasse, crevasses and Serac, seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand.

Granodiorite
Granodiorite () is a coarse-grained (phaneritic) intrusive igneous rock similar to granite, but containing more plagioclase feldspar than orthoclase feldspar. The term banatite is sometimes used informally for various rocks ranging from granite to diorite, including granodiorite. Composition According to the QAPF diagram, granodiorite has a greater than 20% quartz by volume, and between 65% and 90% of the feldspar is plagioclase. A greater amount of plagioclase would designate the rock as tonalite. Granodiorite is felsic to intermediate in composition. It is the intrusive igneous equivalent of the extrusive igneous dacite. It contains a large amount of sodium (Na) and calcium (Ca) rich plagioclase, potassium feldspar, quartz, and minor amounts of muscovite mica as the lighter colored mineral components. Biotite and amphiboles often in the form of hornblende are more abundant in granodiorite than in granite, giving it a more distinct two-toned or overall darker appearan ...

New Zealand
New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 smaller islands. It is the sixth-largest island country by area, covering . New Zealand is about east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland. The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and then developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. In 1840, representatives of the United Kingdom and Māori chiefs ...

Biotite
Biotite is a common group of phyllosilicate minerals within the mica group, with the approximate chemical formula . It is primarily a solid-solution series between the iron-endmember annite, and the magnesium-endmember phlogopite; more aluminous end-members include siderophyllite and eastonite. Biotite was regarded as a mineral ''species'' by the International Mineralogical Association until 1998, when its status was changed to a mineral ''group''. The term ''biotite'' is still used to describe unanalysed dark micas in the field. Biotite was named by J.F.L. Hausmann in 1847 in honor of the French physicist Jean-Baptiste Biot, who performed early research into the many optical properties of mica. Members of the biotite group are sheet silicates. Iron, magnesium, aluminium, silicon, oxygen, and hydrogen form sheets that are weakly bound together by potassium ions. The term "iron mica" is sometimes used for iron-rich biotite, but the term also refers to a flaky micaceous form ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carboniferous
The Carboniferous ( ) is a geologic period and system of the Paleozoic that spans 60 million years from the end of the Devonian Period million years ago ( Mya), to the beginning of the Permian Period, million years ago. The name ''Carboniferous'' means "coal-bearing", from the Latin '' carbō'' ("coal") and '' ferō'' ("bear, carry"), and refers to the many coal beds formed globally during that time. The first of the modern 'system' names, it was coined by geologists William Conybeare and William Phillips in 1822, based on a study of the British rock succession. The Carboniferous is often treated in North America as two geological periods, the earlier Mississippian and the later Pennsylvanian. Terrestrial animal life was well established by the Carboniferous Period. Tetrapods (four limbed vertebrates), which had originated from lobe-finned fish during the preceding Devonian, became pentadactylous in and diversified during the Carboniferous, including early amphibian line ...
