Akatore Fault
The Otago fault system (also known as Otago reverse fault province) contains multiple faults with the potential to have rupture events greater than in magnitude. These are parallel to, and to the east of the Alpine Fault in the south eastern part of the South Island of New Zealand. It accommodates about /year of contraction. Geography East of the Southern Alps, Central Otago has a number of parallel, northeast trending ranges separating broad, flat-bottomed valleys which extend to the coast of Otago. These ranges are associated with the main reverse faults of the system. Near the Southern Alps the faults with this north-east trend continue through Lindis Pass into South Canterbury and so the Dalrachney/Lindis Pass Fault and the Ostler Fault Zone in South Canterbury are geologically related to the Otago fault system. Otago, towards the coast, is separated from South Canterbury by the Waitaki River and the south western aspect of this river valley is defined by mainly normal n ...

Otago
Otago (, ; ) is a regions of New Zealand, region of New Zealand located in the southern half of the South Island and administered by the Otago Regional Council. It has an area of approximately , making it the country's second largest local government region. Its population was The name "Otago" is the local Māori language#South Island dialects, southern Māori dialect pronunciation of "Otakou, Ōtākou", the name of the Māori village near the entrance to Otago Harbour. The exact meaning of the term is disputed, with common translations being "isolated village" and "place of red earth", the latter referring to the reddish-ochre clay that is common in the area around Dunedin. "Otago" is also the old name of the European settlement on the harbour, established by the Weller Brothers in 1831, which lies close to Otakou. The upper harbour later became the focus of the Otago Association, an offshoot of the Free Church of Scotland (1843–1900), Free Church of Scotland, notable for ...

The Catlins
The Catlins (sometimes referred to as The Catlins Coast) comprise an area in the southeastern corner of the South Island of New Zealand. The area lies between Balclutha, New Zealand, Balclutha and Invercargill, straddling the boundary between the Otago and Southland, New Zealand, Southland regions. It includes the South Island's southernmost point, Slope Point. A rugged, sparsely populated area, the Catlins features a scenic coastal landscape and dense temperate rainforest, both of which harbour many endangered species of birds, most notably the rare yellow-eyed penguin. The coast attracts numerous marine mammals, among them New Zealand fur seals and Hooker's sea lions. In general terms the area enjoys a maritime temperate climate. Its exposed location leads to its frequently wild weather and heavy ocean swells, which are an attraction to big wave surfing, big-wave surfers, and have also caused numerous shipwrecks. People have lived in the area since around 1350 AD. Prior to E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water Of Leith (New Zealand)
The Water of Leith (also known as Ōwheo, the River Leith, Leith Stream or Leith Canal), is a small river in the South Island of New Zealand. It rises to the north of the city of Dunedin, flowing for southeast through the northern part of the city and the campus of the University of Otago before reaching the Otago Harbour. The name of the city of Dunedin is the anglicised form of ''Dùn Èideann'' which is the Scottish Gaelic form of the name ''Edinburgh'', and thus the river is also named for the Water of Leith which runs through the Scottish capital. The original Māori name for the stream was ''Ōwheo'' ("The place of Wheo"), Wheo being the name of a local chief whose village stood close to its mouth.Herd, J., and Griffiths, G.J. (1980). ''Discovering Dunedin.'' Dunedin: John McIndoe. This name is now rarely used (but the university's computer science department building is named after it).

Taieri Mouth
Taieri Mouth is a small fishing village at the mouth of the Taieri River, New Zealand. Taieri Island (Moturata) lies in the ocean several hundred metres off the river's mouth. It has a white sand beach for swimming and several picnic areas. Moturata is a distinctive landmark which can be walked to at low-tide. Caution is advised as the tides can change quickly. Another feature is the millennium walking track that follows the Taieri River from the mouth through the lower gorge to Henley. The village is located southwest of central Dunedin on the Southern Scenic Route. It is located in the Clutha District on the boundary of Dunedin City and east of Lake Waihola. Immediately to its south is the smaller settlement of Taieri Beach, and the two are often considered parts of the same settlement. It gained a little notoriety or sadness in the 1990s, relating to the Bain family murders, as the place where Robin Bain worked as the school principal. History There was a Māori occ ...

Tsunami
A tsunami ( ; from , ) is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake. Earthquakes, volcanic eruptions and underwater explosions (including detonations, landslides, glacier calvings, meteorite impacts and other disturbances) above or below water all have the potential to generate a tsunami. Unlike normal ocean waves, which are generated by wind, or tides, which are in turn generated by the gravitational pull of the Moon and the Sun, a tsunami is generated by the displacement of water from a large event. Tsunami waves do not resemble normal undersea currents or sea waves because their wavelength is far longer. Rather than appearing as a breaking wave, a tsunami may instead initially resemble a rapidly rising tide. For this reason, it is often referred to as a tidal wave, although this usage is not favoured by the scientific community because it might give the false impression of ...

Southland Region
Southland () is New Zealand's southernmost region. It consists of the southwestern portion of the South Island and includes Stewart Island. Southland is bordered by the culturally similar Otago Region to the north and east, and the West Coast Region in the extreme northwest. The region covers over 3.1 million hectares and spans 3,613 km of coastline. , Southland has a population of 103,900, making it the eleventh-most-populous New Zealand region, and the second-most sparsely populated. Approximately half of the region's population lives in Invercargill, Southland's only city. The earliest inhabitants of Southland were Māori of the Waitaha iwi, followed later by Kāti Māmoe and Kāi Tahu. Early European arrivals were sealers and whalers, and by the 1830s, Kāi Tahu had built a thriving industry supplying whaling vessels, looked after whalers and settlers in need, and had begun to integrate with the settlers. By the second half of the 19th century these industrie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lewis Pass
Lewis Pass is the northernmost of the three main mountain passes through the Southern Alps in the South Island of New Zealand. With an elevation of 907 metres, it is slightly lower than Arthur's Pass and higher than Haast Pass. The pass is the saddle between the valleys of the Maruia River to the northwest in the West Coast Region and the Lewis River to the southeast in north Canterbury. The small spa of Maruia Springs is close to the saddle, on the West Coast side. Lewis Pass is named after Henry Lewis who, together with Christopher Maling, was the first European to discover the pass, in April 1860 while working as a surveyor of the Nelson Provincial Survey Department. Before this time the pass was used by the Ngāi Tahu Māori of Canterbury to transport pounamu (greenstone) from the west coast. State Highway 7 traverses the pass. The road officially opened on Saturday 30 October 1937. It had a regular bus route over it until Intercity's service was replaced by a ...

Canterbury Plains
The Canterbury Plains () are an area in New Zealand centred in the Mid Canterbury, to the south of the city of Christchurch in the Canterbury region. Their northern extremes are at the foot of the Hundalee Hills in the Hurunui District, and in the south they merge into the plains of North Otago beyond the Waitaki River. The smaller Amuri Plain forms a northern extension of the plains. Geology The Canterbury Plains were formed from Quaternary moraine gravels transported from the Southern Alps and deposited here during glacial periods in the late Pleistocene approximately 3 million to 10,000 years ago. The alluvial gravels were then reworked as shingle fans of several of the larger rivers, notably the Waimakariri, the Rakaia, the Selwyn, and the Rangitata. Part of the Canterbury-Otago tussock grasslands, the land is suitable for moderately intensive livestock farming but is prone to droughts, especially when the prevailing wind is from the northwest. At these times, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southland Syncline
The Southland Syncline is a major geological structure located in the Southland, New Zealand, Southland Region of New Zealand's South Island. The syncline folds the Mesozoic Greywacke, greywackes of the Stratigraphy of New Zealand, Murihiku Terrane. The northern limb of the fold is steep to overturned, while the southern limb dips shallowly to the northeast. The axial plan dips to the northeast and the axis plunges to the southeast. The Murihiku Terrane is formed predominantly from Permian to Jurassic sedimentary rocks with minor igneous intrusions, and is marked by prominent strike ridges particularly on its northern limb due to the steeper dip. These are created from the erosion of alternating strata of sandstone and mudstone. The northern edge of this fold system is marked by the Murihiku Escarpment, at the southern extreme of the Waimea Plains. Many of the names of stage (geology), stages and epoch (geology), epochs in the Permian, Triassic, and Jurassic periods in the New Ze ...

Peneplain
In geomorphology and geology, a peneplain is a low-relief plain formed by protracted erosion. This is the definition in the broadest of terms, albeit with frequency the usage of peneplain is meant to imply the representation of a near-final (or penultimate) stage of fluvial erosion during times of extended tectonic stability. Peneplains are sometimes associated with the cycle of erosion theory of William Morris Davis, but Davis and other researchers have also used the term in a purely descriptive manner without any theory or particular genesis attached. Discussion 390px, Sketch of a hypothetical peneplain formation after an orogeny. The existence of some peneplains, and peneplanation as a process in nature, is not without controversy, due to a lack of contemporary examples and uncertainty in identifying relic examples. By some definitions, peneplains grade down to a base level represented by sea level, yet in other definitions such a condition is ignored. Geomorphologist K ...

Schist
Schist ( ) is a medium-grained metamorphic rock generally derived from fine-grained sedimentary rock, like shale. It shows pronounced ''schistosity'' (named for the rock). This means that the rock is composed of mineral grains easily seen with a low-power hand lens, oriented in such a way that the rock is easily split into thin flakes or plates. This texture (geology), texture reflects a high content of platy minerals, such as mica, talc, chlorite group, chlorite, or graphite. These are often interleaved with more granular minerals, such as feldspar or quartz. Schist typically forms during regional metamorphism accompanying the process of mountain building (orogeny) and usually reflects a medium Metamorphism#Metamorphic grades, grade of metamorphism. Schist can form from many different kinds of rocks, including sedimentary rocks such as mudstones and igneous rocks such as tuffs. Schist metamorphosed from mudstone is particularly common and is often very rich in mica (a ''mica schis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Permian Ophiolite Belt
The Permian ( ) is a geologic period and stratigraphic system which spans 47 million years, from the end of the Carboniferous Period million years ago (Mya), to the beginning of the Triassic Period 251.902 Mya. It is the sixth and last period of the Paleozoic Era; the following Triassic Period belongs to the Mesozoic Era. The concept of the Permian was introduced in 1841 by geologist Sir Roderick Murchison, who named it after the region of Perm in Russia. The Permian witnessed the diversification of the two groups of amniotes, the synapsids and the sauropsids (reptiles). The world at the time was dominated by the supercontinent Pangaea, which had formed due to the collision of Euramerica and Gondwana during the Carboniferous. Pangaea was surrounded by the superocean Panthalassa. The Carboniferous rainforest collapse left behind vast regions of desert within the continental interior. Amniotes, which could better cope with these drier conditions, rose to dominance in place of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
