The garnets provide an interesting example of an isostructural group. The minerals of this group possess the general chemical formula A3B2(SiO4)3. The A lattice site is occupied by large ions such as calcium (Ca), magnesium (Mg), iron (Fe), and manganese (Mn) which possess two bonding electrons.
Mineral class : Sulphates : Anhydrite Gypsum group. Chemical formula : Ca(SO 4). 2H 2 O : Crystal system : Monoclinic. Habitus : Tabular or elongated crystals. Aggregates in the form of roses are called desertroses. Also radiating fibric aggregates. Twinning is common in the form of swallow tails. Grainy or compact aggregates are also common ...
Gold (Au), native copper (Cu), and diamond and graphite, which are made of carbon, are all native element minerals. Recall that a mineral is defined as naturally occurring. Therefore, elements purified and crystallized in a laboratory do not qualify as minerals, unless they have also been found in nature. Mineral Classification Tables
Named "plumbago" in 1739 by Magnus von Bromell, but in a different sense than previous authors such as Agricola and Conrad Gesner. Also called "molybdaena", but "molybdaena" was shown to represent two species, molybdenite and graphite as known today, in 1781 by Carl Wilhelm Scheele. Named graphite in 1789 by Abraham Gottlob Werner from the Greek "graphein", "to write".

Graphite is a mineral of extremes. It is extremely soft, cleaves with very light pressure, and has a very low specific gravity. In contrast, it is extremely resistant to heat and nearly inert in contact with almost any other material. These extreme properties give it a wide range of uses in metallurgy and manufacturing.
Galena Group. Galena is the primary ore mineral of lead. Worked for its lead content as early as 3000 BC, it is found in ore veins with sphalerite, pyrite, chalcopyrite, tennantitetetrahedrite, etc. and in skarns, as well as in sedimentary rocks where it may replace carbonate beds or be deposited in pore spaces.

Both have silicon and oxygen in their family name, so they both belong to the silicate family. Chemical families help to group minerals to look for similar properties. For example, "carbonates'' include the radical "CO 3" which reacts with acids to produce carbon dioxide. Minerals like calcite and azurite will produce a "fizzing" as carbon ...
Minerals that are composed of atoms from a single element are referred to as native elements.. The minerals in the gold group all occur together in the periodic table of elements and have a common crystal structure. They all are soft, can be hammered out into thin sheets (malleable), drawn into wire (ductile), and cut into thin shavings with a knife (sectile).

The carbonate minerals contain the anionic complex (CO 3) 2–, which is triangular in its coordination—, with a carbon atom at the centre and an oxygen atom at each of the corners of an equilateral triangle. These anionic groups are strongly bonded individual units and do not share.
It is scientifically a different mineral than Diamond, and believed to have formed when meteoric Graphite fell to earth. When this happened, great heat and stress transformed the Graphite into Diamond, but it retained Graphite''s hexagonal crystal lattice. For additional information, see .
