The chemical formula of mineral Gormanite is indicated by (Fe,Mg)3Al4(PO4)4(OH)6-2H2O or Hydrated Iron Magnesium Aluminum Phosphate Hydroxide. Gormanite is actually a Phosphate mineral. Gormanite is a relatively new mineral in the mineral world. It was just described in the year 1980 in Canada. The mineral species Gormanite was named after Professor Donald Herbert Groman of the University of Toronto. Gormanite is known to crystallize in the triclinic system of crystal formation. In optical mineralogy, this triclinic crystal system commonly comprises crystals having three axes, of which all are unequal in length and are positioned oblique to one another. Gormanite is most commonly used as mineral specimen and it is often found exhibiting nice and fascinating microscope appearance when viewed with the aid of polarized light microscopes.

 

Gormanite is also found forming a series with another mineral called souzalite. In optical mineralogy, a series is a set of minerals with slight differences in their respective structures and chemical content. The chemical difference is commonly observed just between the two elements that can occupy the same site in the crystal structure and has the capability to substitute for each other. If the substitution can occur as 100 percent element A to 100 percent element B in the site, then a complete series occurs. But in this case of Gormanite and souzalite, the series is probably incomplete between the magnesium rich souzalite and the iron rich Gormanite. Mineral Gormanite is most commonly found forming attractive and colorful mineral specimens that generally show good crystal forms, which can be more fascinating to view under polarized microscope used in optical mineralogy. This is actually a really good addition top anyone’s collection.

 

            Mineral Gormanite is most commonly found showing blue green color that can be more splendidly exhibited when viewed with the aid of polarizing microscopes used in optical mineralogy. Gormanite is most commonly found exhibiting a vitreous luster in reflected light of the petrographic polarizing microscope for mineralogists. Mineral Gormanite also shows indistinct cleavage when it is closely evaluated under a polarizing microscope for used in optical mineralogy. The specific gravity measure of the mineral usually gives an approximate value of about 3.1 grams per cubic centimeters, which is considered average for translucent minerals. The hardness measure of the mineral Gormanite when it is evaluated using the Mohs scale method is usually ranging from 4 to 5. Gormanite mineral section is most commonly found leaving a pale green streak when it is rubbed on a white porcelain streak plate.

 

            Most Gormanite crystals are found translucent to transparent in appearance. The crystal habits of mineral Gormanite as described in optical mineralogy usually include stubby to prismatic crystals and druzy crusts that are usually nice and interesting when viewed with the aid of polarized light microscopes. Some Gormanite crystals can be found in radial form where the crystals radiate from the center without producing stellar forms. This habit is commonly splendidly exhibited under polarizing microscopes for mineralogists. Some Gormanite crystals can be found bladed or aggregates of thin lathlike crystals that are also interesting when viewed with the aid of polarized microscope used in optical mineralogy.

 

            Gormanite is most commonly found showing moderate surface relief when viewed closely with the aid of petrographic polarizing microscopes. Gormanite is most commonly found showing biaxial negative figure when the mineral section is evaluated between crossed nicols of petrographic polarizing microscopes used in optical mineralogy. The maximum birefringence of Gormanite is usually found 0.041 when it is evaluated in plane-polarized light of polarizing microscopes. Gormanite also exhibits strong dispersion under polarizing microscopes for geologists. The refractive index of mineral Gormanite is usually ranging from 1.619 to 1.660. Mineral Gormanite is also non-fluorescent. Mineral There is no specific data found on the toxicity and health dangers for mineral Gormanite. However, the specimens of this mineral species should be treated with great care and use of sensible precaution is advised upon handling them. Gormanite is a no radioactive mineral.

 

            Gormanite is commonly associated with other interesting minerals including phosphates minerals like lazulite, wardite, augelite, ludlamite, goyazite, kulanite, and brazilianite as well as calcite and siderite. The best field indicators of mineral Gormanite usually include color, crystal habit, localities and associations. Gormanite can be found forming in phosphate ironstones. Gormanite is actually one of the new Phosphates coming from the hydrothermal deposits. Gormanite notably occurs at several other localities including The Big Fish, Rapid Creek, and Blow River areas located at Yukon Territory of Canada.
