Busa Del Pomar
'' 'Busa del Pomar' '' is an ancient silver mine located in the north of Italy, just north east Trento. It is one of the major mines (locally called canope) that are part of the old Monte Calisio silver-mining complex. Position and structure The mine is situated at about 600 m asl and is located about 1 km from the village of , near both to Masi Saracini and to Via Claudia Augusta. The mine has three entrances: the lower entrance and the main entrance are connected and continue with a remarkable development of tunnels which are often unstable and passable with difficulty. The third entrance, unlike the previous ones, does not continue in depth but stops almost immediately.

Via Claudia Augusta
The Via Claudia Augusta is an ancient Roman road, which linked the valley of the Po River with Rhaetia (encompassing parts of modern Eastern Switzerland, Northern Italy, Western Austria, Southern Germany and all of Liechtenstein) across the Alps. The route still exists, and since the 1990s increased interest in long-distance hiking and cycling have made the German and Austrian stretches of the Via Claudia Augusta popular among tourists, with the result that modern signage (''illustration'') identifies the revitalised track. Since 2007, the ''Giontech Archeological Site'', in Mezzocorona/Kronmetz (Italy) serves as the Via Claudia Augusta International Research Center with the support of the ''Foundation Piana Rotaliana'' and the Government of the City of Mezzocorona/Kronmetz. History In 15 BC, the Roman general Nero Claudius Drusus, the stepson of Augustus, got orders from his stepfather to improve the passage through the Alps for military purposes and to increase Roman control ...

Bellerophon Formation
Bellerophon (; Ancient Greek: Βελλεροφῶν) or Bellerophontes (), born as Hipponous, was a hero of Greek mythology. He was "the greatest hero and slayer of monsters, alongside Cadmus and Perseus, before the days of Heracles", and his greatest feat was killing the Chimera, a monster that Homer depicted with a lion's head, a goat's body, and a serpent's tail: "her breath came out in terrible blasts of burning flame." Bellerophon was also known for capturing the winged horse Pegasus with the help of Athena’s charmed bridle, and earning the disfavour of the gods after attempting to ride Pegasus to Mount Olympus to join them. Etymology One possible etymology that has been suggested is: Βελλεροφόντης (Bellerophóntēs) from Ancient Greek βέλεμνον (bélemnon), βελόνη (belóne), βέλος (bélos, "projectile, dart, javelin, needle, arrow") and -φόντης (-phóntēs, "slayer") from φονεύω (phoneúō, "to slay").

Galena
Galena, also called lead glance, is the natural mineral form of lead(II) sulfide (PbS). It is the most important ore of lead and an important source of silver. Galena is one of the most abundant and widely distributed sulfide minerals. It crystallizes in the cubic crystal system often showing octahedral forms. It is often associated with the minerals sphalerite, calcite and fluorite. Occurrence Galena is the main ore of lead, used since ancient times, since lead can be smelted from galena in an ordinary wood fire. Galena typically is found in hydrothermal veins in association with sphalerite, marcasite, chalcopyrite, cerussite, anglesite, dolomite, calcite, quartz, barite, and fluorite. It is also found in association with sphalerite in low-temperature lead-zinc deposits within limestone beds. Minor amounts are found in contact metamorphic zones, in pegmatites, and disseminated in sedimentary rock. In some deposits the galena contains up to 0.5% silver, a byprodu ...

Silver
Silver is a chemical element with the Symbol (chemistry), symbol Ag (from the Latin ', derived from the Proto-Indo-European wikt:Reconstruction:Proto-Indo-European/h₂erǵ-, ''h₂erǵ'': "shiny" or "white") and atomic number 47. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. The metal is found in the Earth's crust in the pure, free elemental form ("native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc Refining (metallurgy), refining. Silver has long been valued as a precious metal. Silver metal is used in many bullion coins, sometimes bimetallism, alongside gold: while it is more abundant than gold, it is much less abundant as a native metal. Its purity is typically measured on a per-mille basis; a 94%-pure alloy is described as "0.940 fine". As one of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barite
Baryte, barite or barytes ( or ) is a mineral consisting of barium sulfate ( Ba S O4). Baryte is generally white or colorless, and is the main source of the element barium. The ''baryte group'' consists of baryte, celestine (strontium sulfate), anglesite (lead sulfate), and anhydrite (calcium sulfate). Baryte and celestine form a solid solution (Ba,Sr)SO4. Names and history The radiating form, sometimes referred to as ''Bologna Stone'', attained some notoriety among alchemists for specimens found in the 17th century near Bologna by Vincenzo Casciarolo. These became phosphorescent upon being calcined. Carl Scheele determined that baryte contained a new element in 1774, but could not isolate barium, only barium oxide. Johan Gottlieb Gahn also isolated barium oxide two years later in similar studies. Barium was first isolated by electrolysis of molten barium salts in 1808 by Sir Humphry Davy in England. The American Petroleum Institute specification API 13/ ISO 13500, which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Former Mines
A former is an object, such as a template, gauge or cutting die, which is used to form something such as a boat's hull. Typically, a former gives shape to a structure that may have complex curvature. A former may become an integral part of the finished structure, as in an aircraft fuselage, or it may be removable, being using in the construction process and then discarded or re-used. Aircraft formers Formers are used in the construction of aircraft fuselage, of which a typical fuselage has a series from the nose to the empennage, typically perpendicular to the longitudinal axis of the aircraft. The primary purpose of formers is to establish the shape of the fuselage and reduce the column length of stringers to prevent instability. Formers are typically attached to longerons, which support the skin of the aircraft. The "former-and-longeron" technique (also called stations and stringers) was adopted from boat construction, and was typical of light aircraft built until ...
