Minerals | Special Issue : Graphite Minerals and Graphene
Graphite generally occurs in three forms: microcrystalline, crystalline lump or vein, and crystalline flake. The microcrystalline graphite is formed through contact metamorphism of coal by large scale igneous intrusion. Flake graphite is assumed to form from ancient organic matters during long period of high-grade regional metamorphism.

Vein Graphite Webversion
Vein graphite, also known as lump graphite, is a very special material. The ore is needle-shaped and was once formed in veins of up to one meter in width within cracks in the Earth's crust. This type of graphite is particularly soft, pure and well-suited for applications requiring high electrical conductivity. It is only mined in Sri Lanka.

What is Graphite?
Graphite is formed naturally through the metamorphism of carbon rich materials in rock which leads to the formation of either crystalline flake graphite, fine grained amorphous graphite, or crystalline vein or lump graphite. Graphite is a non-metal but has many properties of metals.
