What kind of rock is a diamond a metamorphic rock an igneous rock or a sedimentary rock?

Answer 1

A diamond is a crystalline mineral form of the element carbon. Igneous, metamorphic, and sedimentary are descriptive terms used to classify types of rocks, not minerals such as diamond.

Diamond is accepted as a valid mineral by the International Mineralogy Association.

Diamonds are found in igneous rock which is brought to the surface of the earth by volcanic eruptions bringing magma to the surface. Diamond itself is strictly an allotrope of the element carbon, a mineral, one form of crystal that can be created from carbon.

However, the diamond itself is a metamorphicmineral, as it forms under heat and pressure from solid-state processes. It forms independently of the igneous rock in which it is found, qualifying it as a type of xenocryst.

Answer 2

No, Diamonds are metamorphic rocks formed by heat and pressure rather than sediments. Some would say that they are noteven metamorphic because they are not really a rock. They are actually minerals, more specifically the mineral form of carbon. But either way they are most certainly not sedimentary rocks.

Answer 3

Diamond is a mineral formed from the element carbon, and is not considered a rock by the classifications in the query.

Answer 4

Diamonds come from the heat and pressure exerted on carbon for a long period of time. So diamonds come from carbon

Answer 5

Well the very early finds of diamond were in India, in alluvial stream beds. Probably there are still some there in 'fossil' stream beds.

Answer 6

Yes. In the earths metamorphic layer the topmost layer is of diamonds.

Answer 7

Diamond is an allotrope of carbon, a mineral, not a rock, and is not classified as a type of rock.

Answer 8

comes from space
