Huntite mineral with formula CaMg3(C03}4 is a
natural carbonatic material with rhombohedral system that its
composition is between dolomite (CaMg(C03h) and magnesite.
For the first time Huntite was found in American Nevada
province, then in other places i,e. Poland, Hungary, France,
Australia, Iran and Greece.
According to thermOdynamic, Huntite forms in condition of
low pressure and tcmpreature in the surface or near surface area.
Investigation in Iran shows the existence ofHuntite mineral
within weathered ultramafic rocks. At outer pan of eastern Iran,
a great bulk of this rocks in ophiOlitic zone is origineted. In
some of this area outcrop of magnesite is in adjacent with
Huntite.
