	Torbernite - Wikipedia, the free encyclopedia
		Torbernite, whose name derives from the Swedish chemist Tornbern Bergmann (1735-1784), is a radioactive, green phosphate mineral, found in granites and other uranium-bearing deposits as a secondary mineral.
		Torbernite is isostructural with a related uranium mineral, autunite, with torbernite's lack of fluorescence a notable difference.
		As torbernite is radioactive, collectors are urged to take proper precautions in the handling and storage of any specimens.

	Uranium Ore Minerals
		Torbernite and meta-torbernite are hydrous copper uranium phosphates, the only difference between the two being the number of water molecules present; their physical properties are identical.
		The principal non uranium minerals associated with torbernite are the clay minerals, limonite, quartz, pyrite, and the copper sulfides and carbonates.
		Like torbernite and meta-torbernite, autunite and meta-autunite are identical in their physical properties, the distinction being made on the basis of the number of water molecules present.

	Metatorbernite - Wikipedia, the free encyclopedia
		Metatorbernite (or meta-torbernite) is a radioactive phosphate mineral, and is a dehydration pseudomorph of torbernite.
		However, more commonly, it is formed by the dehydration of torbernite, which causes internal stress and breakage within the crystal lattice, resulting in crystals composed of microscopic powder held together using electrostatic force, and having a lighter green colour, opaque diaphaneity, and a relatively dull lustre.
		It is especially closely associated with torbernite, but is also found amongside autunite, meta-autunite and uraninite.

	Alpha Track - Uranium Mineralization Concepts
		Autunite and torbernite and their "meta" forms are widespread, found mostly as fracture fillings, joint coating and crystals.
		Autunite and torbernite are commonly found together, and where crystallized, occur as thin to thick tabular plates.
		torbernite is apple to emerald green in colour, contains copper and is found in the oxidized zones of copper-ruanium deposits.

	TORBERNITE (Hydrated Copper Uranyl Phosphate)
		Torbernite is a popular mineral among collectors who seek uranium bearing minerals.
		Torbernite can lose water and convert to a different mineral called meta-torbernite of the meta-autunite/meta-torbernite group of minerals.
		The presence of torbernite crystal has been used by prospectors as an indicator of profitable uranium ore in the area.

	Torbernite
		Torbernite is a 20 year old young man who would rather be anyone than himself.
		He often poses as other people, and so no one is really sure he is who he says he is. When he first came to the Dark Kingdom, his name was Momiji Ryuuichi.
		Torbernite's unwillingness to face reality is something of a problem.

	Torbernite (Site not responding. Last check: 2007-10-30)
		Because of this, prospectors used torbernite as an indicator of possible profitable uranium strikes and it is itself an important ore of uranium.
		Torbernite is chemically unstable and will dehydrate in open air forming metatorbernite.
		Notable occurances of torbernite are Shrinklobwe, Shaba, Zaire; Cornwall, England; and North Carolina, USA.

		Torbernite is a Uranium bearing mineral whose structure is composed of Phosphate tetrahedrons linked to Uranium-oxygen groups that form distorted octahedrons.
		Crystal habits of Torbernite include tabular square crystals dominated by two pinacoid faces, formations in parallel growths (looking like a stacked book), and as crusts, micaceous, foliated and scaly aggregates.
		Torbernites conversion is less dramatic, involving the lose of a few water molecules only.

		-Metatorbernite being formed by the dehydration of Torbernite, and it is therefore a pseudomorph of Torbernite, and not the true crystal form of Metatorbernite.
		When Torbernite loses water, there is ~16% shrinkage in its unit cell volume, which causes a large internal stress to develop within the crystal lattice.

	Autunite - LoveToKnow 1911
		Though closely resembling the tetragonal torbernite in form, it crystallizes in the orthorhombic system and is optically biaxial.
		The colour is sulphur-yellow, and this enables the mineral to be distinguished at a glance from the emerald-green torbernite.
		Autunite is usually found with pitchblende and other uranium minerals, or with ores of silver, tin and iron; it sometimes coats joint-planes in gneiss and pegmatite.

		The relationship between such minerals as autunite and meta-autunite, uranocircite and metauranocircite (Cook 1994), and torbernite and metatorbernite are but a few examples of this phenomenon.
		Certainly one could list all known torbernite localities and be relatively safe, but that leaves out the important possibility that metatorbernite occurs naturally in circumstances in which it was the original species and did not form by dehydration of torbernite.
		Torbernite is typically considered a secondary mineral formed by the weathering or oxidation of other uranium-beating minerals.
