http://www.webmineral.com/data/Grossular.shtml WebMagnetite is a black, opaque, magnetic mineral that leaves a black streak when rubbed across a hard rough surface. It is one of the most abundant metal oxides, and its crystal structure contains both the ferrous (Fe+2) and ferric (Fe+3) forms of iron ions. A complex pattern of electrons between the two forms of iron is the source of its ...

WebApr 11, 2024 · Demantoid is a rare and famous green garnet, spessartine (also called spessartite) is an orange garnet, and rhodolite is a beautiful purple-red garnet. Garnets can even exhibit the color-change phenomenon similar to the rare gemstone alexandrite. All garnets have essentially the same crystal structure, but they vary in chemical composition. WebMineralogically and chemically, rhodolite garnets are members of the pyrope- almandine solid-solution series, with an approximate bulk garnet composition of Py 70 Al 30. [1] WebApr 17, 2024 · The silicate molecule (SiO4) is a part of the complex chemical formula for garnet. What is garnet chemical composition? There is a general chemical formula of R3R2( SiO4)3 where R3 is a bivalent (giving up two electrons) metal and R2 is a trivalent (giving up three electrons) metal in the mineral. qualitative research is naturalistic
