Mount Moehau
The Moehau Range is the northernmost range on the Coromandel Peninsula, extending from the settlement of Colville, New Zealand northwards to the tip of the peninsula. Mount Moehau is the highest point of the range, at 892m above sea level. Physical geography The Moehau Range is the central feature of the Colville Ecological District. Environment Waikato's local area planting guide describes the area as "long ridges and steep streams radiating out to the coast, steep and broken hillslopes, floodplains, harbours and estuaries." The Colville Ecological District takes in , 59% of which is in indigenous vegetation, and 8% of which is virgin forest. To the south the range is drained by Waikawau River. Geology Most of the range is made up of metamorphic, prehnite-pumpellyite Manaia Hill Group greywackeˌ sandstones and siltstones (Waipapa terrane) of Jurassic/Cretaceous age, formed about 150 million years ago. They have few fossils, but are interbedded with feldspar-lithic volcani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coromandel Peninsula
The Coromandel Peninsula ( mi, Te Tara-O-Te-Ika-A-Māui) on the North Island of New Zealand extends north from the western end of the Bay of Plenty, forming a natural barrier protecting the Hauraki Gulf and the Firth of Thames in the west from the Pacific Ocean to the east. It is wide at its broadest point. Almost its entire population lives on the narrow coastal strips fronting the Hauraki Gulf and the Bay of Plenty. In clear weather the peninsula is clearly visible from Auckland, the country's biggest city, which lies on the far shore of the Hauraki Gulf, to the west. The peninsula is part of the Thames-Coromandel District of the Waikato region. Origin of the name The Māori name for the Coromandel comes from the Māori legend of Māui and the Fish, in which the demigod uses his hook to catch a great fish from the depths of te Moana-Nui-a-Kiwa (The Pacific Ocean). ''Te Tara-O-Te-Ika-A-Māui'' means 'The spine of Māui's fish'. The spine can be understood to be the C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hornblende
Hornblende is a complex inosilicate series of minerals. It is not a recognized mineral in its own right, but the name is used as a general or field term, to refer to a dark amphibole. Hornblende minerals are common in igneous and metamorphic rocks. The general formula is . Physical properties Hornblende has a hardness of 5–6, a specific gravity of 3.0 to 3.6, and is typically an opaque green, dark green, brown, or black color. It tends to form slender prismatic to bladed crystals, diamond-shaped in cross-section, or is present as irregular grains or fibrous masses. Its planes of cleavage intersect at 56° and 124° angles. Hornblende is most often confused with the pyroxene series and biotite mica, which are also dark minerals found in granite and charnockite. Pyroxenes differ in their cleavage planes, which intersect at 87° and 93°. Hornblende is an inosilicate (chain silicate) mineral, built around double chains of silica tetrahedra. These chains extend the length of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Strand Station
The Strand Station, also referred to as Auckland Strand Station, is a railway station located on the eastern edge of the Auckland CBD. It serves as the long-distance railway station for Auckland. It is the northern terminus of the Northern Explorer service between Auckland and Wellington, and the northern terminus for the Te Huia service on Saturdays from 24 July 2021. Suburban services are not scheduled to pass through the station, however, it serves as a backup for Britomart Transport Centre during times of disruption. The platforms were formerly part of the Auckland Railway Station complex which was opened in 1930 on Beach Road, replacing the previous railway terminus which was on the Queen Street site where Britomart now stands. The 1930 station was the third to serve as the rail terminus for Auckland, and remained the sole station serving the CBD until its closure in July 2003, when Britomart became the new terminus. The original Platform 7 (now referred to as Platform 1) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Auckland Ferry Terminal
The Auckland Ferry Terminal, also called the Downtown Ferry Terminal, is the hub of the Auckland ferry network, which connects the Auckland CBD with suburbs in North Shore, West Auckland, and South Auckland, and islands in the Hauraki Gulf. The terminal is on the Auckland waterfront, at the north end of Queen Street, across Quay Street from the Britomart Transport Centre, which is the hub for local buses and trains. The ferry terminal is composed of two main elements, a yellow Edwardian Baroque building facing Queen Street and the CBD, and newer wharves and a waiting area building (the actual ferry terminal of today) facing the Waitematā Harbour. Facilities Edwardian building By the early 20th century, the Auckland Harbour Board recognised the need for a dedicated ferry building in Auckland. Original plans were for a five-storey structure, but after public outrage at the height, a design of four storeys and a clock tower was proposed. The plan was similar to that of th ...

Auckland War Memorial Museum
The Auckland War Memorial Museum Tāmaki Paenga Hira (or simply the Auckland Museum) is one of New Zealand's most important museums and war memorials. Its collections concentrate on New Zealand history (and especially the history of the Auckland Region), natural history, and military history. The present museum building was constructed in the 1920s in the neo-classicist style, and sits on a grassed plinth (the remains of a dormant volcano) in the Auckland Domain, a large public park close to the Auckland CBD. Auckland Museum's collections and exhibits began in 1852. In 1867 Aucklanders formed a learned society – the Auckland Philosophical Society, later the Auckland Institute. Within a few years the society merged with the museum and '' Auckland Institute and Museum'' was the organisation's name until 1996. Auckland War Memorial Museum was the name of the new building opened in 1929, but since 1996 was more commonly used for the institution as well. From 1991 to 2003 the muse ...

Britomart Transport Centre
Britomart Transport Centre, also known as Britomart railway station, is the public transport hub in the Auckland Central Business District, central business district of Auckland and the northern terminus of the North Island Main Trunk railway line. It combines a railway station in a former Edwardian architecture, Edwardian post office, extended with expansive Modern architecture, modernist architectural elements, with a bus interchange. It is at the foot of Queen Street, Auckland, Queen Street, the main commercial thoroughfare of the CBD, with the main ferry terminal just across Quay Street, Auckland, Quay Street. The centre was the result of many design iterations, some of them being substantially larger and including an underground bus terminal and a large underground car park. Political concerns and cost implications meant that those concepts did not proceed. However, at the time of its inception in the early 2000s the centre was still Auckland's largest transport project e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parliament House, Wellington
Parliament House ( mi, Te Whare Paremata), in Lambton Quay, Wellington, is the main building of the New Zealand Parliament Buildings. It contains the debating chamber, speaker's office, visitors' centre, and committee rooms. It was built between 1914 and 1922, replacing an earlier building that burned down in 1907. Parliament started using the yet to be completed building from 1918. Parliament House was extensively earthquake strengthened and refurbished between 1991 and 1995. It is open for visitors almost every day of the year, and is one of Wellington's major visitor attractions. Parliament House is a Category I heritage building registered by Heritage New Zealand. Architecture Parliament House was designed in an Edwardian neoclassical style. It was deliberately designed to display New Zealand materials; the building is faced with Takaka marble, with a base course of Coromandel granite.

Quartz Diorite
Quartz diorite is an igneous, plutonic ( intrusive) rock, of felsic composition, with phaneritic texture. Feldspar is present as plagioclase (typically oligoclase or andesine) with 10% or less potassium feldspar. Quartz is present at between 5 and 20% of the rock. Biotite, amphiboles and pyroxene The pyroxenes (commonly abbreviated to ''Px'') are a group of important rock-forming inosilicate minerals found in many igneous and metamorphic rocks.

Porphyry (geology)
Porphyry ( ) is a textural term for an igneous rock consisting of coarse-grained crystals such as feldspar or quartz dispersed in a fine-grained silicate-rich, generally aphanitic matrix or groundmass. The larger crystals are called phenocrysts. In its non-geologic, traditional use, the term ''porphyry'' refers to the purple-red form of this stone, valued for its appearance. The term ''porphyry'' is from the Ancient Greek (), meaning "purple". Purple was the color of royalty, and the "imperial porphyry" was a deep purple igneous rock with large crystals of plagioclase. Some authors claimed the rock was the hardest known in antiquity. Thus, "imperial"-grade porphyry was prized for monuments and building projects in Imperial Rome and thereafter. Subsequently, the name was given to any igneous rocks with large crystals. The adjective ''porphyritic'' now refers to a certain texture of igneous rock regardless of its chemical and mineralogical composition. Its chief characteris ...

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] |
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] |
Diorite
Diorite ( ) is an intrusive igneous rock formed by the slow cooling underground of magma (molten rock) that has a moderate content of silica and a relatively low content of alkali metals. It is intermediate in composition between low-silica (mafic) gabbro and high-silica ( felsic) granite. Diorite is found in mountain-building belts (''orogens'') on the margins of continents. It has the same composition as the fine-grained volcanic rock, andesite, which is also common in orogens. Diorite has been used since prehistoric times as decorative stone. It was used by the Akkadian Empire of Sargon of Akkad for funerary sculptures, and by many later civilizations for sculptures and building stone. Description Diorite is an intrusive igneous rock composed principally of the silicate minerals plagioclase feldspar (typically andesine), biotite, hornblende, and sometimes pyroxene. The chemical composition of diorite is intermediate, between that of mafic gabbro and felsic grani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
