    01.09.2008· The formation of kimberlite-hosted diamond deposits is a long-lived and complex series of processes that first involved the growth of diamonds in the mantle, and later their removal and transport to the earth's surface by kimberlite magmas. Dating of inclusions in diamonds showed that diamond growth occurred several times over geological time. Many diamonds are of Archaean age and many

    Four processes are thought to be responsible for virtually all of the natural diamonds that have been found at or near Earth's surface. One of these processes accounts for nearly of all diamonds that have ever been mined. The remaining three are insignificant sources of commercial diamonds.

    Le diamant (dja.mã) est l'allotrope de haute pression du carbone, métastable à basses température et pression. Moins stable que le graphite et la lonsdaléite qui sont les deux autres formes de cristallisation du carbone, sa renommée en tant que minéral lui vient de ses propriétés physiques et des fortes liaisons covalentes entre ses atomes arrangés selon un système cristallin cubique.
