Graphite: The mineral Graphite information and pictures
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.

Non Silie MineralsProperties of Chemical Element
The majority basic group of nonsilie minerals is known as the native elements. 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.

Iran is home to 68 minerals with more than 37 billion tons of proven and 57 billion tons of potential reserves. Barite is a generally white or colorless mineral primarily used as a weighting agent for drilling fluids in oil and gas exploration.
Family of Minerals msnucleus
200757&ensp·&enspFAMILY OF MINERALS . The chemical composition of a mineral determines the overall geometric arrangements of that mineral. How the atoms bond with each other determines other properties including crystal shape, cleavage, behavior of light, and hardness.. Chemical families are divided into classes depending on the anion or positive radical that is part of their chemical formula.

In which mineral group does it belong? Carbonates. What mineral fizzes when it comes in contact with hydrochloric acid? Calcite. Dull, Silky, Waxy, Pearly, and Earthy are terms that describe which property of minerals? Diamond and graphite have the same chemical composition. Compare and contrast these two to explain why diamond is a gem and
Graphite: Mineral information, data and localities.
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".

How do minerals change without melting? and it might just transform back to graphite! Above is the stability ranges for the three guys I mentioned above, diamond occurs four times higher than this diagram (more than 120km into our mantle)! What type of nonsilie mineral group does calcite belong to?
2.3 Mineral Groups – Physical Geology
2.3 Mineral Groups Most minerals are made up of a ion (a positively charged ion) or several ions and an anion (a negatively charged ion (e.g., S 2–)) or an anion complex (e.g., SO 4 2–). For example, in the mineral hematite (Fe 2 O 3), the ion is Fe 3 + (iron) and the anion is O 2– (oxygen). We group minerals into classes on the basis of their predominant anion or anion group.
Schist Metamorphic rocks
Amphibolebearing rocks with a lineated fabric belong to this group. Schistosity is a type of foliation, characterised by the preferred orientation of elongated or platy mineral grains (which are abundant in schistose rocks). Schistosity is a result of pressure in the crust which forces the grains to align perpendicular to the force applied.
