The Mineral azurite. Azurite owes its name to its beautiful azure-blue color, which makes it a very popular and well-known mineral. Large, well-formed, and deep blue crystals from Tsumeb (Namibia), Bisbee (Arizona), and Milpillas (Mexico), make exquisite collector's minerals that are regarded as some of the finest mineral masterpieces in nature.
Historique de la description et appellations Inventeur et étymologie. Décrite par François Sulpice Beudant en 1832, le nom dérive de la composition chimique (nickel).. Synonymie. En raison de sa couleur rouge cuivre, le minerai est souvent appelé « cuivre-nickel » : l'équivalent allemand « Kupfernickel » a été employé dès 1694.
Breithauptite This mineral is relatively common in the veins at Cobalt and was one of the first minerals noted during the initial discovery. At the time, it was mistaken for a copper mineral, probably because of its peculiar pink-red metallic color. Breithauptite occurs in the veins at Cobalt as masses, sometimes filling the entire vein or replacing other arsenides/sulfides and silver.
There are 66 individual minerals that contribute to the typical computer that are identified above. There are others,in addition to those above, but it should be evident that without many minerals, there would be no computers, or televisions, for that matter.
This is a very nice specimen consisting of pale copper red masses of the uncommon nickel mineral NICKELINE, also known as NICCOLITE, on all sides from the Frontier Mine, Timiskaming District, Ontario, Canada. The specimen is 2.45 by 1.4 cms in size.
From very early times nickel-bearing minerals, such as niccolite, were mixed with glass to create green glass.. Nickel. When nickel was extracted from niccolite, the mineral name was a logical source of the name for the element, nickel.. Nickel. He named the new metal nickel after the mineral name of niccolite..

Sulfide minerals are compounds in which sulfur is combined as an anion with a metal (or semi-metal) cation or cations. The definition is commonly widened to include minerals in which the anion is As or Sb, sometimes together with S, and to include Se and Te minerals. The sulfosalts are a special group of the sulfide minerals that have a general
niccolite, bismuthenite. The aplites, with the associated metallic minerals, are thought to be late-stage differentiates from the tholeiitic magma from which the diabase was formed and indicate that such a magma may yield minerals carrying Co, As, S, Ni, Ag, and Bi. The major mineralization
Nickeline is a nickel arsenide mineral. The analyses by Oen et al. (1984) show it to be fairly constant in composition and slightly antimonian. Nickeline, also called niccolite, occurred in an isolated, anomalous assemblage in the Trotter Shaft at Franklin. It was a rare occurrence, apparently very limited in extent, and has not been found ...
Minerals and mineral collecting are part of life in the Keweenaw. E. W. Heinrich, in his book Mineralogy of Michigan, recently revised by George W. Robinson, has compiled lists, descriptions and localities of Keweenaw Minerals.There are three groups of minerals in the Keweenaw. The first are primary minerals, which make up the lavas and redbeds.
Description; Additional information; Nickeline or Niccolite. A mineral consisting of nickel arsenide (NiAs) containing 43.9% nickel and 56.1% arsenic. Small quantities of sulfur, iron and cobalt are usually present, and sometimes the arsenic is largely replaced by …
Formula: NiAs Hexagonal Description: Nickeline, also referred to as "niccolite", is a rare mineral found in high temperature hydrothermal deposits, especially those in mafic igneous rocks. Other nickel minerals, pyrrhotite and chalcopyrite are commonly associated. ASHLAND COUNTY: Nickeline is found as a minor component of a hydrothermally mineralized zone found in drill core taken from the ...
Nickeline is named for its nickel composition, being one the primary nickel minerals. In the 1600's, it was thought to have contained copper due to its bronze color, and was known as kupfernickel ("kupfer" is copper in German.)It was officially named Nickeline by French mineralogist Francois Sulpice Beudant in 1832, and subsequently renamed Niccolite by James Dwight Dana in 1868, derived from ...
Metallic minerals that have been reported are: niccolite, skutterudite, gersdorffite, rammelsbergite, annabergite, erythrite, arsenopyrite, native antimony, pyrite and chalcopyrite. The main zone, which occurs near the margin of a diabase dyke, is located across the SW limb of a conjugate fault system with the massive niccolite lens in a ...
Metasedimentary bedrock of coastal Maine contains a diverse suite of As-bearing minerals that act as significant sources of elements found in ground and surface waters in the region. Arsenic sources in the Penobscot Formation include, in order of decreasing As content by weight: löllingite and realgar (c.70%), arsenopyrite, cobaltite, glaucodot, and gersdorffite (in the range of 34–45% ...

Minerals, singly or in combination, make up rocks. For example, subequal amounts of quartz and alkali-feldspar, sometimes with biotite and plagioclase, make up granite, a common crustal igneous rock (triangular diagram at the top of the figure). All minerals, like all materials, consist of one or more elements, the building blocks of all matter.
Niccolite is an arsenide of nickel mineral. Niccolite's color ranges from a gray to a copper color. Arsenic can be replaced by antimony. The specific gravity of this mineral ranges from 7.3 to 7.7, and it may contain small quantities of iron, cobalt or sulphur. Due to its …

The body needs many minerals; these are called essential minerals. Essential minerals are sometimes divided up into major minerals (macrominerals) and trace minerals (microminerals). These two groups of minerals are equally important, but trace minerals are needed in smaller amounts than major minerals.
