Bolzano
Bolzano ( or ; german: Bozen, (formerly ); bar, Bozn; lld, Balsan or ) is the capital city of the province of South Tyrol in northern Italy. With a population of 108,245, Bolzano is also by far the largest city in South Tyrol and the third largest in historical Tyrol. The greater metro area has about 250,000 inhabitants and is one of the urban centers within the Alps. Bolzano is the seat of the Free University of Bozen-Bolzano, where lectures and seminars are held in English, German, and Italian. The city is also home to the Italian Army's Alpini High Command (COMALP) and some of its combat and support units. In the 2020 version of the annual ranking of quality of life in Italian cities, Bolzano was ranked joint first for quality of life alongside Bologna. Along with other Alpine towns in South Tyrol, Bolzano engages in the Alpine Town of the Year Association for the implementation of the Alpine Convention. The Convention aims to promote and achieve sustainable developme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magnesite
Magnesite is a mineral with the chemical formula (magnesium carbonate). Iron, manganese, cobalt, and nickel may occur as admixtures, but only in small amounts. Occurrence Magnesite occurs as veins in and an alteration product of ultramafic rocks, serpentinite and other magnesium rich rock types in both contact and regional metamorphic terrains. These magnesites are often cryptocrystalline and contain silica in the form of opal or chert. Magnesite is also present within the regolith above ultramafic rocks as a secondary carbonate within soil and subsoil, where it is deposited as a consequence of dissolution of magnesium-bearing minerals by carbon dioxide in groundwaters. Isotopic structure: clumped isotope The recent advancement in the field of stable isotope geochemistry is the study of isotopic structure of minerals and molecules. This requires study of molecules with high resolutions looking at bonding scenario (how heavy isotopes are bonded to each other)- leading to kno ...

Wilhelm Karl Ritter Von Haidinger
Wilhelm Karl Ritter von Haidinger (or Wilhelm von Haidinger, or most often Wilhelm Haidinger) (5 February 179519 March 1871) was an Austrian mineralogist. Early life Haidinger's father was the mineralogist Karl Haidinger (1756–1797), who died when Wilhelm was only two years old. The books on mineralogy and the collection of rocks and minerals of his father will almost certainly have raised the interest of young Wilhelm. The collection of his uncle, banker Jakob Friedrich van der Nüll, was by far larger and much more precious, even to such a degree that the famous professor Friedrich Mohs of Freiberg (Germany) had been asked to describe it in detail. Young Wilhelm Haidinger and the professor often met in the house of Wilhelm's uncle. After completing the "Normalschule" and the "Grammatikalschule" Wilhelm started out his pre-academical training at the local "Gymnasium". However, after completing only his first year, the "Humanitätsclasse", Wilhelm (now 17 years old) was asked by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pfitsch
Pfitsch (; it, Val di Vizze ) is a ''comune'' (municipality) South Tyrol in northern Italy, located about north of the city of Bolzano, on the border with Austria. It is named for the valley of Pfitschtal or Pfitscher Tal. Geography As of 30 November 2010, it had a population of 2,966 and an area of .All demographics and other statistics: Italian statistical institute Istat.

Zillertal
The Ziller Valley (german: Zillertal) is a valley in Tyrol, Austria that is drained by the Ziller River. It is the widest valley south of the Inn Valley (german: Inntal) and lends its name to the Zillertal Alps, the strongly glaciated section of the Alps in which it lies. The Tux Alps lie to its west, while the lower grass peaks of the Kitzbühel Alps are found to the east. The Ziller Valley is one of the valley areas in Tyrol most visited by tourists. Its largest settlement is Mayrhofen. Geography The Ziller Valley branches from the Inn trench near Jenbach, about 40 km northeast of Innsbruck, running mostly in a north–south direction. The Ziller Valley proper stretches from the village of Strass to Mayrhofen, where it separates into four smaller valleys, the Tux valley and the sparsely settled, so-called ''Gründe'' – Zamsergrund, Zillergrund and Stilluppgrund. Along the way, two more ''Gründe'' and the Gerlos valley, which leads to the Gerlos Pass and into Salzburg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tyrol (state)
Tyrol (; german: Tirol ; it, Tirolo) is a States of Austria, state (''Land'') in western Austria. It comprises the Austrian part of the historical County of Tyrol, Princely County of Tyrol. It is a constituent part of the present-day Euroregion Tyrol–South Tyrol–Trentino (together with South Tyrol and Trentino in Italy). The capital of Tyrol is Innsbruck. Geography The state of Tyrol is separated into two parts, divided by a strip. The larger territory is called North Tyrol (''Nordtirol'') and the smaller area is called East Tyrol (''Osttirol''). The neighbouring Austrian state of Salzburg (state), Salzburg stands to the east, while on the south Tyrol has a border with the Italy, Italian province of South Tyrol (Trentino-Alto Adige/Südtirol) which was part of the Austro-Hungarian Empire before the First World War. With a land area of , Tyrol is the third-largest state in Austria. Tyrol shares its borders with the federal state of Salzburg in the east and Vorarlberg in th ...

Magnesium Minerals
Magnesium is a chemical element with the symbol Mg and atomic number 12. It is a shiny gray metal having a low density, low melting point and high chemical reactivity. Like the other alkaline earth metals (group 2 of the periodic table) it occurs naturally only in combination with other elements and it almost always has an oxidation state of +2. It reacts readily with air to form a thin passivation coating of magnesium oxide that inhibits further corrosion of the metal. The free metal burns with a brilliant-white light. The metal is obtained mainly by electrolysis of magnesium salts obtained from brine. It is less dense than aluminium and is used primarily as a component in strong and lightweight alloys that contain aluminium. In the cosmos, magnesium is produced in large, aging stars by the sequential addition of three helium nuclei to a carbon nucleus. When such stars explode as supernovas, much of the magnesium is expelled into the interstellar medi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iron(II) Minerals
Iron () is a chemical element with symbol Fe (from la, ferrum) and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table. It is, by mass, the most common element on Earth, right in front of oxygen (32.1% and 30.1%, respectively), forming much of Earth's outer and inner core. It is the fourth most common element in the Earth's crust. In its metallic state, iron is rare in the Earth's crust, limited mainly to deposition by meteorites. Iron ores, by contrast, are among the most abundant in the Earth's crust, although extracting usable metal from them requires kilns or furnaces capable of reaching or higher, about higher than that required to smelt copper. Humans started to master that process in Eurasia during the 2nd millennium BCE and the use of iron tools and weapons began to displace copper alloys, in some regions, only around 1200 BCE. That event is considered the transition from the Bronze Age to the Iron Age. In t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
