	Franklinite
		Franklinite is a zinc spinel, an iron zinc oxide, named for the type locality Franklin (Sussex Co., New Jersey, USA), and for Benjamin Franklin (1706-1790) for whom Franklin was named.
		Franklinite is dark grey to fl with a submetallic luster, but contrary to most ore minerals it is not completely opaque - very thin chips are slightly translucent with red colour.
		Franklinite is for all practical purposes stable in a normal household environment.

	Origin Franklin ore deposit (Site not responding. Last check: 2007-10-09)
		The composition of franklinite, as shown by these analyses, reveals the very significant fact that all the iron present is ferric iron, with the exception of one specimen.
		The absence of ferrous iron in all but one analysis of franklinite and the very small quantities of it in the other ore minerals is strong proof for the writer's theory of a fully oxidized ore body as the source of the present ores.
		The franklinite was formed by the dehydration of the limonite, manganite, and the slightly hydrous hematite and pyrolusite, in the presence of ZnCO

	Franklinite (Site not responding. Last check: 2007-10-09)
		Franklinite is one of the minerals found at Franklin, New Jersey, a world famous locality that has produced many formerly unknown and exotic mineral species.
		Specimens from Franklin often contain the rounded fl grains of franklinite surrounded by white calcite and/or greenish willemite with a sprinkling of red zincite.
		Franklinite’s hardness is 6, and its specific gravity ranges from 5.0 to 5.2, which is slightly above the average for metallic minerals.

	Franklinite crystal on calcite - Sterling Hill, Ogdensburg, NJ (Site not responding. Last check: 2007-10-09)
		Franklinite is an oxide of zinc, manganese, and iron.
		This nice specimen is the result of countless attempts to recover an intact crystal from a franklinite - calcite - willemite boulder that sits on the Mine Run Dump at Sterling Hill.
		Quality of specimens seems to be directly proportional to the time spent on that boulder and inversely proportional to the number of pieces knocked loose with any one hammer swing...

	Franklinite
		Franklinite a Zinc Iron Oxide of the Spinel Group is named after Franklin, New Jersey, the locality where it was first discovered.
		Franklinite is a rare mineral world wide, but it is the dominant mineral of the zinc deposits found at Franklin and Sterling Hill, in Sussex County New Jersey.
		The Franklinite deposits in New Jersey are part of a massive hydro thermal replacement depost (limestones and dolimites), with both massive Franklinite beds, and small granular crystals.

	Fluorescent Minerals
		Franklinite is a zinc iron ore. Franklinite was named after Franklin, New Jersey, the town where it was discovered.
		Franklinite does not fluoresce, but is often found with calcite and willemite.
		In the UV illuminated image the orange mineral is calcite and the green mineral is willemite.

	Franklinite Mine 1 - IronMiners.com
		The Franklinite Mine was in fact the only commercial mine where the mineral franklinite was an important ore of iron.
		The deposit consisted of a massive body of franklinite that was as wide as 100 feet in some areas but irregular in width.
		The tunnel was merely a haulageway where the ore was transported from the open pit.

	Franklinite - basic information
		Franklinite is a major component of the Zn-Mn-Fe orebodies at Franklin and Sterling hill, and was mined in great quantity as an ore of zinc.
		Franklinite is fl in color, and transparent reddish-brown in small fragments.
		Franklinite has a normal spinel-type structure and contains zinc, manganese and iron.

	Franklinite - LoveToKnow 1911
		FRANKLINITE, a member of the spinel group of minerals, consisting of oxides of iron, manganese and zinc in varying proportions, (Fe, Zn, Mn)"(Fe, Mn) 2"'0 4.
		Associated with franklinite at Franklin Furnace, and found also at some other localities, is another member of the spinel group, namely, gahnite or zinc-spinel, which is a zinc aluminate, ZnAl 2 O 4, with a little of the zinc replaced by iron and manganese.

		The red ore, which is a nick name for Franklinite, was thought to be magnetic (magnetite).
		After the 1850's Franklinite was found to be an excellent source for ores such as zinc, iron and manganese.

	rock bookends
		Primarily zincite and franklinite, the zinc ore also has streaks of white calcite and willamite that fluoresce bright red and green under UV light.
		The bookends are extremely heavy at 17 pounds which eliminated the possibility of flat lap polishing on the cut surface.
		The combination of gemmy red zincite and metallic octahedrons of franklinite is an interesting and attractive set of bookends and a great presentation for a mineral specimen considered rare world wide.

	Re: Franklinite as a detector mineral?? (Site not responding. Last check: 2007-10-09)
		I've never see any reference to Franklinite, or any form of magnetite, being used profitably as a detector.
		The confusion may come from the fact that Franklinite is often found with zincite which is used in combination with another mineral, e.g.
		Zincite in a form of zinc oxide with a dark orange color.

		Franklin, N.J. Zincite, ZnO, is a very rare mineral found in large amounts exclusively at Franklin, N.J., intimately intergrown with franklinite.
		Both zincite and franklinite are highly colored, the zincite possibly by the manganese ion (Palache et al., 1944), the franklinite primarily by the ferric ion.
		Both the ferrous and ferric ions are primarily responsible for the fall- off in reflectivity towards the blue and for the crossover for different particle size samples.
