The chemical composition of the mineral Moschellandsbergite is indicted by the formula Ag2Hg3, Silver Mercury or silver amalgam. This Moschellandsbergite belongs to the Native Element. This silver amalgam is considered as a very very minor ore of silver and mercury. It is also used as mineral specimen wherein it usually exhibits a nice and interesting appearance when viewed under geological polarizing light microscopes. Despite the fact that this alloy Moschellandsbergite is a chemical compound, it is classified as element. This is due to the metallic bond possessed by this Moschellandsbergite, which is very much similar to the bonds of those more pure metallic elements. Thus, because of this, Moschellandsbergite is classified under Native Elements Class.
Moschellandsbergite was first described in 1938 at its type of locality in Germany. This mineral has incredibly long name and is also incredibly rare in occurrence. It was named after its type of locality at Landsberg, Germany, which is formerly Moschellandsberg. This locality in fact has produced many specimens of many mercury minerals that exhibit interesting appearance when evaluated with the aid of the polarizing microscopes. This locality has also produce some rather obscure mercury minerals especially the mercury alloys.
Mineral Moschellandsbergite is usually found having silver-white to gray color that is more fascinatingly interesting when viewed under geological polarizing microscopes.? The luster that is commonly found exhibited by the mineral in reflected light of the polarizing microscope is usually metallic. The cleavage of mineral Moschellandsbergite is usually not seen when viewed under polarizing microscope for geologists. The fracture that is usually found when Moschellandsbergite is examined closely under polarizing microscope is usually conchoidal. The hardness measure of the mineral when it is evaluated using the Mohs scale method is usually 3.5. When specimen of Moschellandsbergite is rubbed on a white porcelain streak plate, it is usually found leaving a gray streak. The specific gravity measure if the mineral is usually found ranging from 13.6 grams per cubic centimeters to 13.7 grams per cubic centimeters, which is considered well above average, even for metallic minerals.
Moschellandsbergite is known to crystallize in the isometric system, which can be seen clearly visible under a polarizing light microscope for geologists. This isometric system comprises crystals having three axes, all of which are perpendicular to one another and all are found equal in lengths. Most crystals of the mineral species are found opaque in appearance. The crystal habits of Moschellandsbergite usually include small rhombic dodecahedral crystal and globular masses that can be seen majestically exhibited under petrographic polarizing light microscopes.
Moschellandsbergite is an isotropic mineral species. This means that it has no power to produce any illumination and it consequently appears totally dark when viewed at different angels between crossed nicols of the polarized microscopes. Since Moschellandsbergite is an isotropic mineral, it has no birefringence display even closely evaluated under petrographic polarizing microscopes. Moschellandsbergite is commonly found associated with other interesting mineral species such as mercury, cinnabar, calomel and many other mercury minerals. There is no specific data found on the toxicity and health danger for mineral Moschellandsbergite. However, the specimens of the mineral species should be treated with great care and use of sensible precaution is advised upon handling them. Moschellandsbergite is a non-radioactive mineral species.
The best field indicators of mineral Moschellandsbergite usually include density, color, crystal habit, and locality. Moschellandsbergite has limited occurrence to its type of locality at Landsberg, Germany.
