Vanadinite
Vanadinite is a mineral belonging to the apatite group of phosphates, with the chemical formula Pb5( V O4)3 Cl. It is one of the main industrial ores of the metal vanadium and a minor source of lead. A dense, brittle mineral, it is usually found in the form of red hexagonal crystals. It is an uncommon mineral, formed by the oxidation of lead ore deposits such as galena. First discovered in 1801 in Mexico, vanadinite deposits have since been unearthed in South America, Europe, Africa, and North America. Origins Vanadinite is an uncommon mineral, only occurring as the result of chemical alterations to a pre-existing material. It is therefore known as a secondary mineral. It is found in arid climates and forms by oxidation of primary lead minerals. Vanadinite is especially found in association with the lead sulfide, galena. Other associated minerals include wulfenite, limonite, and barite. It was originally discovered in Mexico by the Spanish mineralogist Andrés Manuel del Río ...

Azurite
Azurite is a soft, deep-blue copper mineral produced by weathering of copper ore deposits. During the early 19th century, it was also known as chessylite, after the Type locality (geology), type locality at Chessy, Rhône, Chessy-les-Mines near Lyon, France. The mineral, a basic carbonate with the chemical formula Cu3(CO3)2(OH)2, has been known since ancient times, and was mentioned in Pliny the Elder's ''Natural History (Pliny), Natural History'' under the Greek name (κυανός: "deep blue," root of English ''cyan'') and the Latin name ''caeruleum''. Since antiquity, azurite's exceptionally deep and clear blue has been associated with low-humidity desert and winter skies. The modern English name of the mineral reflects this association, since both ''azurite'' and ''Azure (color), azure'' are derived via Arabic language, Arabic from the Persian language, Persian (لاژورد), an area known for its deposits of another deep-blue stone, lapis lazuli ("stone of azure").

Anglesite
Anglesite is a lead sulfate mineral with the chemical formula PbSO4. It occurs as an oxidation product of primary lead sulfide ore, galena. Anglesite occurs as prismatic orthorhombic crystals and earthy masses, and is isomorphous with barite and celestine. It contains 74% of lead by mass and therefore has a high specific gravity of 6.3. Anglesite's color is white or gray with pale yellow streaks. It may be dark gray if impure. It was first recognized as a mineral species by William Withering in 1783, who discovered it in the Parys copper-mine in Anglesey; the name anglesite, from this locality, was given by F. S. Beudant in 1832. The crystals from Anglesey, which were formerly found abundantly on a matrix of dull limonite, are small in size and simple in form, being usually bounded by four faces of a prism and four faces of a dome; they are brownish-yellow in colour owing to a stain of limonite. Crystals from some other localities, notably from in Sardinia, are transparent and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Regions Of Morocco
Regions are currently the highest administrative divisions in Morocco. Since 2015, Morocco officially administers 12 regions, including one (Dakhla-Oued Ed-Dahab) that lies completely within the disputed territory of Western Sahara and two (Laâyoune-Sakia El Hamra and Guelmim-Oued Noun) that lie partially within it. The regions are subdivided into a total of 75 second-level administrative divisions, which are Prefectures and provinces of Morocco, prefectures and provinces. A region is governed by a directly elections in Morocco, elected regional council. The president of the council is responsible for carrying out the council's decisions. Prior to the 2011 Moroccan constitutional referendum, 2011 constitutional reforms, this was the responsibility of the Wali, the representative of the central government appointed by the King, who now plays a supporting role in the administration of the region.

Oriental (Morocco)
Oriental région or Oujda region ( ar, الشرق, aš-šarq; ber, ⵜⴰⴳⵎⵓⴹⴰⵏⵜ, tagmuḍant) is one of the twelve regions of Morocco, located in the north-eastern part of the country. It covers an area of 90,127 km² and has a population of 2,314,346 (2014 census) and is the easternmost region of Morocco. The capital and the largest city is Oujda, and the second largest city is Nador. The region includes 7 provinces and one prefecture. Mohamed Mhidia became wali (governor) of the region in 2015.

Provinces Of Morocco
In Morocco, the 75 second-level administrative subdivisions are 13 prefectures and 62 provinces. They are subdivisions of the 12 regions of Morocco. Each prefecture or province is subdivided into arrondissements (only in prefectures of some metropolitan areas), municipalities (''communes'', sing. ''commune'') or urban municipalities (''communes urbaines'', sing. ''commune urbaine'') in other urban areas, and districts (''cercles'', sing. ''cercle'') in rural areas. The districts are subdivided into rural municipalities (''communes rurales'', sing. ''commune rural''). One prefecture (Casablanca) is also subdivided into ''préfectures d'arrondissements'' (sing. ''préfecture d'arrondissements''), similar to districts (''cercles'') except they are grouping a few arrondissements instead of rural municipalities. Note: The arrondissements and (urban) municipalities should probably be thought of as fourth-level subdivisions, on the same level as the rural municipalities, but they are no ...

Western European Time
Western European Time (WET, UTC±00:00) is a time zone covering parts of western Europe and consists of countries using UTC±00:00 (also known as Greenwich Mean Time, shortly called GMT). It is one of the three standard time zones in the European Union along with Central European Time and Eastern European Time. The following Western European countries and regions use UTC±00:00 in winter months: *Portugal, since 1912 with pauses (except Azores, UTC−01:00) *United Kingdom and Crown Dependencies, since 1847 in England, Scotland, Wales, the Channel Islands, and the Isle of Man, and since 1916 in Northern Ireland, with pauses *Ireland, since 1916, except between 1968 and 1971 *Canary Islands, since 1946 (rest of Spain is CET, UTC+01:00) *Faroe Islands, since 1908 * Madeira islands, since 1912 with pauses * North Eastern Greenland ( Danmarkshavn and surrounding area) *Iceland, since 1968, without summer time changes All the above countries except Iceland implement daylight savi ...

Western European Summer Time
Western European Summer Time (WEST, UTC+01:00) is a summer daylight saving time scheme, 1 hour ahead of Greenwich Mean Time and Coordinated Universal Time. It is used in: * the Canary Islands * Portugal (including Madeira but not the Azores) * the Faroe Islands The following countries also use the same time zone for their daylight saving time but use a different title: *United Kingdom, which uses British Summer Time (BST) *Ireland, which uses Irish Standard Time (IST) ( (ACÉ)). Also sometimes erroneously referred to as "Irish Summer Time" (). The scheme runs from the last Sunday in March to the last Sunday in October each year. At both the start and end of the schemes, clock changes take place at 01:00 UTC+00:00. During the winter, Western European Time (WET, GMT+0 or UTC±00:00) is used. The start and end dates of the scheme are asymmetrical in terms of daylight hours: the vernal time of year with a similar amount of daylight to late October is mid-February, well before ...

Mississippi Valley-Type
Carbonate-hosted lead-zinc ore deposits are important and highly valuable concentrations of lead and zinc sulfide ores hosted within carbonate (limestone, marl, dolomite) formations and which share a common genetic origin. These ore bodies range from 0.5 million tonnes of contained ore, to 20 million tonnes or more, and have a grade of between 4% combined lead and zinc to over 14% combined lead and zinc. These ore bodies tend to be compact, fairly uniform plug-like or pipe-like replacements of their host carbonate sequences and as such can be extremely profitable mines. This classification of ore deposits is also known as Mississippi Valley Type or ''MVT'' ore deposits, after a number of such deposits along the Mississippi River in the United States, where such ores were first recognised; these include the famed Southeast Missouri Lead District of southeastern Missouri, and deposits in northeast Iowa, southwest Wisconsin, and northwest Illinois.
