	Greenockite - LoveToKnow 1911
		GREENOCKITE, a rare mineral composed of cadmium sulphide, CdS, occurring as small, brilliant, honey-yellow crystals or as a canary-yellow powder.
		Isomorphous with greenockite is the hexagonal zinc sulphide (ZnS) known as wurtzite.
		Previous to the recent discovery in Sardinia of cadmium oxide as small octahedral crystals, greenockite was the only known mineral containing cadmium as an essential constituent.

	GREENOCKITE Chapter 21. Sulfides, arsenides, antimonides, and sulfosalts
		Greenockite was noted as an unconfirmed species by Canfield (1899) and Palache (1908, 1935), but this material has been found to be a mixture including hawleyite.
		Greenockite is yellow to orange-yellow and occurs as powdery encrustations and thin films for the most part.
		Greenockite is a cadmium sulfide mineral isostructural with wurtzite.

	Greenockite (Site not responding. Last check: 2007-10-13)
		Greenockite was first described by Jameson, and Connell, in 1840, who examined specimens found in a railway cutting at Bishopton, on the south bank of the River Clyde, a few miles west of Glasgow.
		Greenockite is one of the select band of minerals named after Scots or Scottish localities.Others include strontianite, caledonite, lanarkite, susannite, scotlandite, macphersonite, leadhillite, edingtonite, thomsonite, mattheddleite, and mullite.
		greenockite is fairly common as a bright yellow powdery stain on weathered zinc-rich ores at Wanlockhead in Dumfriesshire.

	Greenockite
		Greenockite is not found in crystals but only as a lemon-yellow powdery incrustation on limestone containing franklinite and fibrous green willemite.
		From the very small amount of material available for a test a distinct coating on charcoal was obtained indicative of cadmium; nevertheless the determination of the mineral is unsatisfactory.
		Greenockite is known only on specimens from Hamburg mine, an early and long-abandoned opening on the northernmost outcrop of the western leg of the ore body at Franklin.

	Greenockite - Wikipedia, the free encyclopedia
		Greenockite is a rare cadmium mineral that consists of cadmium sulfide, CdS, in crystalline form.
		It occurs as massive encrustations and as six-sided pyramidal crystals which vary in color from a honey yellow through shades of red to brown.
		Greenockite occurs with other sulfide minerals such as sphalerite and galena.

	GREENOCKITE (Cadmium Sulfide)
		Greenockite has the same structure as the zinc iron sulfide wurtzite.
		The tetrahedrons in greenockite all are oriented in one direction and produce the hexagonal (six fold rotational) symmetry.
		Crystals of greenockite are typically six sided pyramids where the hemimorphic character is easily seen as the top of the crystal is the point and the bottom of the crystal is the pyramid's base.

		Description: Greenockite is a bright yellow mineral formed by hydrothermal fluids.

	Cadmium
		Cadmium is often associated in small quantities (0.1—1%) with zinc ores such as sphalerite (ZnS), however the only commercially viable ore of the metal is greenockite (CdS), which theoretically contains 77.7% cadmium.
		Greenockite occurs in a yellow powdery form in the zinc ores of Missouri.
		Almost all cadmium is obtained as a by-product in the treatment of zinc, copper and lead ores.

		Greenockite regularly occurs as yellowish, powdery coatings or as a colouring pigment in other minerals,
		First discovered when constructing a railway tunnel between Glasgow and Greenock in the 19th century, it was described as a new species by Professor Jameson of Edinburgh University, in 1840, and named after Lord Greenock, the landowner.
		Brown, a Scottish collector of the period, had greenockite crystals in his collection pre-dating that year, but these were assumed to be an unusual form of sphalerite (zinc sulphide).
