Kimberliittimagma
Kimberliittimagma is a theoretical magma type proposed in high‑pressure petrological studies to explain certain deep‑mantle melt compositions. The term combines “kimberlite,” a well‑known mafic volcanic rock that originates from the mantle, and the suffix “magma,” indicating a molten material. Kimberliittimagma has been suggested to exist at depths exceeding 700 kilometers, where temperatures reach between 1,300 and 1,500 degrees Celsius and pressures exceed 25 kilobars.
The composition of kimberliittimagma is thought to be low in oxygen fugacity, high in silicon and magnesium,
Kimberliittimagma is of interest to geoscientists because it could provide a mechanism for transporting volatile components
Despite its theoretical foundation, direct sampling of kimberliittimagma is currently impossible due to the inaccessible depth
