SphaleriteSphalerite is a sulfide mineral with the chemical formula(Zn, Fe)S. It is the most important ore of zinc. Sphalerite is found in a variety of deposit types, but it is primarily in sedimentary exhalative, Mississippi-Valley type, and volcanogenic massive sulfide deposits. It is found in association with galena, chalcopyrite, pyrite (and other sulfides), calcite, dolomite, quartz, rhodochrosite, and fluorite.
Silicate mineralSilicate minerals are rock-forming minerals made up of silicate groups. They are the largest and most important class of minerals and make up approximately 90 percent of Earth's crust. In mineralogy, the crystalline forms of silica (SiO2) are usually considered to be tectosilicates, and they are classified as such in the Dana classification system (75.1). However, the Nickel–Strunz classification categorizes them as oxide minerals (4.DA).
Gerard TroostGerardus Troost (March 5, 1776 – August 14, 1850) was a Dutch-American medical doctor, naturalist, mineralogist, and founding member and first president of the Philadelphia Academy of Natural Sciences. BiographyTroost was born in Den Bosch, Netherlands, to Anna Cornelia (Van Heeck) and Everardus Josephus Troost. He was the older brother of Benoist Troost.
ManganeseManganese is a chemical element; it has the symbol Mn and atomic number 25. It is a hard, brittle, silvery metal, often found in minerals in combination with iron. First isolated in the 1770s, manganese is a transition metal with many industrial alloy uses, particularly in stainless steels in which it improves strength, workability, and resistance to wear.
Armand Lévy (mineralogist)Serve-Dieu Abailard "Armand" Lévy (14 November 1795 – 29 July 1841) was a French mathematician and mineralogist. He is remembered for the Haüy-Lévy notation for describing mineral crystal structures. LifeLévy was born in Paris where his Jewish businessman father had married Céline Mailfert, a Catholic. Although his birth and death records list his names as Serve-Dieu Abailard, he registered with the Geological Society of London under the name Armand.
UltravioletUltraviolet radiation (UV; sometimes called ultraviolet light) is electromagnetic radiation of wavelengths of 100–400 nanometers, shorter than that of visible light, but longer than vacuum ultraviolet and extreme ultraviolet (radiation bands that overlap UV but share some properties with soft X-rays). UV radiation is present in sunlight and constitutes about 10% of the total electromagnetic radiation output from the Sun.
FluorescenceFluorescence is one of two kinds of photoluminescence, the emission of light by a substance that has absorbed light or other electromagnetic radiation. When exposed to ultraviolet radiation, many substances will glow (fluoresce) with colored visible light. The color of the light emitted depends on the chemical composition of the substance. Fluorescent materials generally cease to glow nearly immediately when the radiation source stops.

William I of the NetherlandsWilliam I (Willem Frederik; 24 August 1772 – 12 December 1843) was King of the Netherlands and Grand Duke of Luxembourg from 1815 until his abdication in 1840. Born as the son of William V, Prince of Orange, the last stadtholder of the Dutch Republic, and Wilhelmina of Prussia, William experienced significant political upheavals early in life.
Vieille MontagneThe Société des mines et fonderies de zinc de la Vieille-Montagne (French; lit.'Company for Mines and Foundries of Zinc at Vieille-Montagne') was a Belgian mining company which produced zinc. The company took its name from an important zinc mine known as "old mountain" or "old mine" (Altenberg) located near Kelmis.*As an Amazon Associate I earn from qualifying purchases.
