	Haematite or Hematite - Gemstone Information (Site not responding. Last check: 2007-10-19)
		Haematite is a compact form of iron oxide.
		Haematite is sometimes used as beads to imitate fl pearls.
		Haematite is often carved as a cameo or sealstone, and is very commonly seen in gent's rings with a crude intaglio carving of a helmeted warrior's head.

	Wholesale haematite included quartz crystals from TOPROCK minerals and crystals
		Haematite is often ground down to a powder and then reconstituted with a resin.
		When haematite crystals are found in a pattern that resembles the petals of a flower, they are called "iron roses" while the shiny crystals are known as "specular haematite" The word specular comes from the Latin word for mirror, and this form of haematite is indeed often used in the manufacture of reflective surfaces.
		Haematite is both a primary and a secondary mineral.

	HAEMATITE, or HEMATITE - Online Information article about HAEMATITE, or HEMATITE
		Haematite has no distinct cleavage, but may show, in consequence of a lamellar structure, a tendency to parting along certain planes.
		Much haematite occurs in a compact or massive form, often mammillary, and presenting on fracture a fibrous structure.
		The hard haematite is occasionally cut and polished as an ornamental stone, and certain kinds have been made into beads simulating fl pearls.

	Haematite and Ferric Oxide (IARC Summary & Evaluation, Supplement7, 1987)
		Underground haematite miners have a higher incidence of lung cancer in the presence of exposure to radon daughters (although other agents might also contribute to the risk) than surface haematite miners [ref: 1-11].
		Haematite mining with low-grade exposure to radon daughters and silica dust was not associated with excess lung cancer in a relatively large cohort [ref: 12].
		The importance of exposure to radon daughters in the occurrence of lung cancer in haematite miners is also suggested by the time trend of lung cancer rates in a mining population [ref: 4].

	Semi-Precious Beads - Haematite Shapes. Stars, hearts, cubes and ovals.
		Haematite is a polished iron ore. It has a metallic fl appearance, although the text book says it should be red due to the oxides in the stone.
		Haematite is a heavy stone and is believed to promote Anti-depression.
		The haematite ovals that we stock are 6mm long and 3mm in width.

	Ilmenite - LoveToKnow 1911 (Site not responding. Last check: 2007-10-19)
		It crystallizes in the parallel faced hemihedral class of the rhombohedral system, thus having the same degree of symmetry as phenacite and pyrophanite, but differing from that of haematite.
		and (Fe,Mg)0 in this ratio of 1:1, yet there is often an excess of ferric oxide to be accounted for; this may perhaps be explained by the regular intergrowth on a minute scale of ilmenite with haematite, like the intergrowth of such substances as calcite and sodium nitrate, which are similar crystallographically but not chemically.
		Ilmenite has a fl streak; it is opaque, but in very thin scales sometimes transparent with a clovebrown colour.

	Catalyst of a sintered iron oxide-containing article - Patent 4789659
		Reduction of the sintered iron oxide article to an iron article is conveniently conducted by passing a current of a reducing gas such as hydrogen and/or carbon monoxide over the sintered iron oxide articles at a temperature in the range 300 to 1200.degree.
		Haematite was milled to a fine powder, having a median particle size of 3.mu.m, all the particles having a size below 10.mu.m.
		958 parts by weight of the milled haematite powder was then mixed with 31 parts by weight of alumina trihydrate, and 11 parts by weight of calcium carbonate, both of which had been previously ground to a similar degree of fineness as the haematite.

	Geological Society - News - Blueberries spied on Mars, explained on Earth
		They are rich in iron, in the form of grey haematite (identified using the Mössbauer spectroscope on the rover) that probably formed in a wet environment.
		Marjorie Chan and her team from the University of Utah had wondered if there might be haematite concretions on Mars, given the red sediments present there, and the suggestions of water flow at some time in the past.
		They were familiar with haematite balls, concretions that range from a few millimetres to 20 centimetres across, and weather out from red sandstone in Zion and Capitol Reef national parks, Grand Staircase-Escalante National Monument, Snow Canyon State Park and the Moab area, in southern Utah.

		Haematite (blue-white) occurs as very poorly polished fine-grained intergrowths cementing silicate grains (low reflectance, right top and bottom); as rounded martite grains pseudomorphing magnetite (centre right) and as single coarse-grained crystals (top centre, bottom left).
		Haematite occurs as very fine crystals (right) that lie along the basal cleavage of phyllosilicates; as martite (blue-white, bottom centre); as a medium grained mosaic (top left) and as authigenic lanceolate euhedral crystals (top left) overgrowing detrital haematite.
		Haematite as martite pseudomorphs after magnetite (two crystals, centre right) and as a rounded lath-shaped pseudomorph (bottom centre) is white and shows faint bireflectance (blue-white to white, centre right).

		The Spirit rover on Mars has identified haematite at a location half way around the planet to where its twin buggy Opportunity found the same mineral.
		Haematite is normally formed in the presence of water - certainly on Earth.
		Spirit's discovery was made in front of the so-called Columbia Hill in a very odd-shaped rock dubbed the "Pot of Gold" by US space agency scientists.

	Haematite and Iron Oxide (IARC Summary & Evaluation, Volume 1, 1972)
		On the basis of epidemiological evidence, exposure to haematite dust may be regarded as increasing the risk of lung cancer development in man.
		The risk is manifest in underground workers but not surface workers, and it is not known whether the excess risk is due to radioactivity in the air of mines, the inhalation of iron oxide or silica, or to a combination of these or other factors.
		There is no evidence that iron-ore dust (haematite) or iron oxide influences the incidence of cancers at sites other than the lungs.

	GeoArch: Experimental smelting - ores
		Although rather different in physical properties, this imported ore is reasonably close to the less siliceous Llanharry and Miskin haematites in its chemical composition, as well as being fairly close to a Forest of Dean or Glamorgan goethite after roasting.
		The Llanharry haematite was used for smelts 6 and 8.
		The Sishen haematite was used for smelts 20, 21, 22, 23, 24 and 25.

	Geological Society - News - Mars — rust bucket of the Solar System
		Grey haematite is not the sort of rust you might expect to find on a desert-dry planet like Mars.
		The coarse-grained structure of grey haematite is important, says ASU's Jack Farmer, head of the NASA Astrobiology Institute's Mars Focus Group, because "to get that kind of coarsening of the crystallinity, you would need to have a reasonable amount of water available" where the haematite formed.
		The peaks and valleys of this graph are characteristic of infrared emissions from haematite.

	Swaziland National Trust Commission - Iron Mines in Malolotja
		Enquiries by Boshier among the Swazis elicited the information that haematite deposits had been mined in historic times and that it was the custom to fill in the excavation to avoid offending the spirits of the underworld.
		The question was why would people interested in haematite go to all the trouble to mine a material that could easily be got by opencast.
		At Lion Cavern it is estimated that at least 1 200 tons of soft haematite ore, rich in specularite, had been removed in ancient times.

	Minotaur hits two new haematite systems
		Minotaur says that regional drilling at Mt Woods intersected a new massive haematite body at the Proteus prospect, 6km southeast of Prominent Hill, and encountered a further haematite alteration system at the Triton prospect, another 1.5km to the south.
		From the top of basement at 74m, the drillhole intersected a dense, massive haematite rock (average 38% iron) with quartz-carbonate veining that continued to 130m depth, followed by haematite- chlorite- and magnetite-altered sediments and breccia to 188m.

		In one of the mines they were lying among and beneath thousands of tons of red iron oxide known as haematite.
		The question was why would people interested in haematite go to all the trouble to mine a material that could easily be got by mining the surface.
		These quarries were removed in the course of modern mining, but C14 dates obtained beforehand place the beginnings of iron ore mining at about 400 AD although it is thought that ancient opencast mines date to about 2 000 BC during the Late Stone Age.

		Drill holes were drilled on 400 metre by 40 metre spacings and have confirmed that the mineralisation is continuous over a strike length of 2.6 kilometres and is open both along strike and down dip.
		The drilling confirmed the high grade tenor of the haematite iron mineralisation combined with low levels of deleterious containments.
		Test pitting and metallurgical testwork on several of the identified haematite scree deposits will be initiated with a view to determining reserves sufficient to allow mining to proceed.

	[Jewelry making - Article 01169] - [Orchid] Magnetic Haematite?
		They were little balls, magnetic enough that they stuck together, had the usual haematite lustre, except that under the 10x loupe the surfaces could be seen to be pitted, the pits not being close enough together to diminish the polish, but yet being fairly uniformly distributed over the (blueberry size) "haematite" balls.
		Now, haematite is not naturally magnetic (or at least only marginally so, certainly not enough for two pieces to stick together).
		I seem to remember however that haematite, heated sufficiently, transforms into magnetite, which can be strongly magnetized.

		Because palaeomagnetic negative directions are very close to the present-day dipolar field, a rock magnetic and SEM study was conducted in order to check the primary nature of the remanent magnetization and to identify the nature and origin of the remanence carriers.
		In some sites, a mixture of haematite and magnetite carries the remanence of both polarities.
		These results reinforce the low palaeolatitude of the Amazon craton at the time of the Marinoan ice age.
