Their most frequent condition is cuboidal, Nevertheless they might also form octahedra, dodecahedra, macles, or put together shapes. The construction is the result of quite a few impurities with sizes in between one and 5 microns. These diamonds likely fashioned in kimberlite magma and sampled the volatiles.[twenty]

the way in which a mineral forms helps identify its id. Diamond types below superior temperature and tension situations that exist only within a selected depth assortment (about 100 miles) beneath the earth’s surface.

This really is aided by isotopic dating and modeling from the geological history. Then surveyors ought to go to the region and obtain samples, trying to find kimberlite fragments or indicator minerals. The latter have compositions that reflect the circumstances in which diamonds form, for example Extraordinary soften depletion or substantial pressures in eclogites. nonetheless, indicator minerals could be misleading; an even better method is geothermobarometry, wherever the compositions of minerals are analyzed as when they were in equilibrium with mantle minerals.[sixty six]
