The chemical formula of mineral Laueite is indicated by MnFe2(PO4)2(OH)2 – 8H2O or Hydrated Manganese Iron Phosphate Hydroxide. Laueite is actually a Phosphate mineral. Laueite is also a member of the Paravauxite Group of minerals. Laueite mineral was named after Max Felix Theodor von Laue (1879 – 1960), a professor of physics at the Kaiser-Wilhelm Institute at Berlin, Germany and in the University of Gottingen, Gottingen, Germany. Mineral Laueite was first described in 1954 at the Hagendorf South Pegmatite at Bavaria, Germany. Laueite 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.

 

Laueite is dimorphous with another interesting mineral called stewartite. In optical mineralogy dimorphous minerals have the same formula but with different structures. This mineral Stewartite was named after its type of locality at Stewart Mine, Pala, San Diego County, California. Mineral Stewartite was actually first discovered from this locality. Laueite is commonly used as mineral specimen and it is often found exhibiting nice and fascinating appearance when viewed under petrographic polarizing microscopes used in optical mineralogy. Laueite is a rare phosphate mineral that shows interesting microscope images under geological polarizing microscopes.

 

            Mineral Laueite is most commonly found showing yellow, orange, honey-brown, orange-yellow or brown color that could appear more splendidly exhibited with viewed under polarizing light microscope used in optical mineralogy. Laueite is also commonly found exhibiting vitreous luster when evaluated in reflected light of polarized microscopes for mineralogists. Laueite is most commonly found exhibiting perfect cleavage and this can be seen more clearly visible when closely examined with the aid of petrographic polarizing microscope used in optical mineralofy. Laueite is alos usually found with conchoidal fracture that that is more clearly visible when viewed with the aid of polarizing microscope for mineralogists. The specific gravity measure of the mineral Laueite usually gives an approximate value ranging from 2.4 grams per cubic centimeters, which is considered average. The hardness measure of mineral Laueite when it is evaluated using the Mohs scale method is usually 3. Laueite is most commonly found leaving a white streak when it is rubbed on a white porcelain streak plate.

 

            Most Laueite crystals are found translucent to transparent. The habit of mineral Laueite as described in optical mineralogy usually include wedge-shaped to tabular or prismatic crystals that are usually interesting when viewed under polarizing microscopes for mineralogists. Laueite can be also found forming fibrous crusts that can be more fascinating and majestically exhibited when viewed under polarizing light microscope for mineralogists. Laueite is most commonly found forming small crystals that can be very well formed and can be found showing splendid images under polarizing microscopes for geologists or the ones used in optical mineralogy. Although Laueite mineral is composed of manganese, its crystals are wonderfully colorful most especially when viewed under petrographic polarizing light microscopes. When viewed closely under polarized light microscope used in optical mineralogy, mineral Laueite can exhibit an attractive honey-brown coloration. This is actually its typical and most noteworthy color.

 

            Laueite is most commonly found exhibiting a moderate surface relief when viewed under several adjustments on the aperture diaphragm of the polarizing microscope for mineralogists. Laueite is most commonly found showing biaxial negative figure when evaluated between crossed nicols of polarizing microscopes for mineralogists. The refractive index of mineral Laueite is usually found ranging from 1.588 to 1.682. The maximum birefringence of mineral Laueite when it is evaluated between crossed polars of petrographic polarizing microscope is usually found 0.092. Laueite also shows weak dispersion when viewed under polarized microscopes used in optical mineralogy. There is no specific data found on the toxicity and health dangers for mineral Laueite. However, the specimens of this mineral species should be treated with great care and use of sensible precaution is advised upon handling them. Laueite is a non-radioactive mineral species.

 

            Mineral Laueite Laueite is commonly found associated with other interesting minerals such as limonite, strunzite, stewart and others. The best field indicators of mineral Laueite usually include color, perfect cleavage, locality, associations and crystal habit. Laueite can be found at the famous Palermo Miner in New Hampshire. The minerals that are found from the Palermo Mine, such as Laueite, are result of the phosphate rich pegmatitic intrusion that has undergone extensive alteration. From this mineralogically famous mineral site, dozens of unusual and rare but attractive primary and secondary phosphate minerals have been found. Laueite is actually one of those wonderful minerals found from Palermo Mine. The mineral notably occurs at the Black Hills region of South Dakota in USA as well as Hagendorf in Germany and of course the famous Palermo Mine in New Hampshire, USA.
