Dec 30, 2012· Diamond is not considered a rock forming mineral. The group of minerals that diamond belongs to is called native elements. Other members of this group are gold, platinum, and copper none of this group is a rock forming mineral.
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.

Dec 04, 2015· Pseudomorphism! Cool word isn''t it? This is a really cool way that a mineral can change its atomic structure without melting. But note that the mineral doesn''t change its chemical composition in this case. An example, a mineral such as Kyanite ("Al"_2"SiO"_5) has three forms which it can exist in depending on the pressure and temperature conditions.
What mineral group does the diamond belong to? Diamond is an elemental mineral. Read More. ... What is graphite mineral group? Graphite is a form of carbon, as is Diamond Read More.
Talc is known for being the softest mineral on earth. It is number 1 on the Mohs hardness scale, and can be easily scratched by a is not commonly seen in collections, as it is usually uninteresting and fairly common, although a few deeply colored and .
These elements are those with chemical formulae consisting of an only one element. In the conversation of the polymorphs two significant native element minerals were discussed, graphite and diamond. Further minerals of this group comprise native sulfur, gold, silver and copper. The left over five main groups of nonsilicate minerals are ...
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 ...
Sep 13, 2009· Graphite is an element. It is made of carbon. Other elements that are found in nature are copper, silver and gold, but they are metals and carbon is not a metal. Sulpher is another nonmetal element that is found is nature. So diamonds and graphite is in a very small group of nonmetallic elements that are found in nature.
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 another polymorph. The two share the same chemistry, carbon, but have very different structures and properties. Diamond is hard, Graphite is soft (the "lead" of a pencil). Diamond is an excellent electrical insulator, Graphite is a good conductor of electricity. Diamond is the ultimate abrasive, Graphite is a very good lubricant.

Molybdenite is a mineral of molybdenum disulfide, Mo S in appearance and feel to graphite, molybdenite has a lubricating effect that is a consequence of its layered atomic structure consists of a sheet of molybdenum atoms sandwiched between sheets of sulfur atoms. The MoS bonds are strong, but the interaction between the sulfur atoms at the top and bottom of separate ...

Graphite is a mineral composed exclusively of the element carbon. Graphite has the same chemical composition as Diamond, which is also pure carbon, but the molecular structure of Graphite and Diamond is entirely different. This causes almost opposite characteristics in their physical properties.
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.
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
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 .
Dolomite: A Mineral and a Rock "Dolomite" is a word that is used by geologists in two different ways: 1) as the name of the mineral dolomite; and, 2) as the name of a rock known as dolomite, dolostone, or dolomite rock. This page is about the mineral dolomite. If .
No. Mineral Mineral Group Formula 1 graphite C 2 sulfur I: native elements S 3 copper Cu 4 sphalerite ZnS 5 pyrite II: sulfides FeS2 6 chalcopyrite CuFeS2
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 ...
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.
May 28, 2007· So diamonds and graphite is in a very small group of nonmetallic elements that are found in nature. I should have been more precise. After reading the following answer I will modify my answer and state that graphite and diamonds are two different forms of the nonmetallic element carbon.
