Most diamonds are metasomatic minerals, which means they grew from fluids or melts that
moved through solid mantle rocks and chemically interacted with them. The involvement of …

Minerals included in diamonds provide direct information about the petrologic and chemical
environment of diamond crystallization. They record information relating to local and …

Porphyry deposits arguably represent the most economically important class of nonferrous
metallic mineral resources. These magmatic-hydrothermal deposits are characterized by …

One of the key scientific questions about diamonds is “how are they formed?” To answer this
question, we need to know the diamond-forming reactions and the physicochemical …

Studies of the inclusions contained in natural diamonds have shown the occurrence of
minerals which must have formed at depths below the lithosphere and which may be closely …

Diamonds originate in the deep roots of ancient continental blocks (cratons) that extend into
the diamond stability field beneath about 140 km. Over the last two decades, rare diamonds …

Nanometre-sized isolated inclusions have been studied in four cloudy octahedral diamonds
from the Internatsionalnaya and one from the Yubileynaya mines (Yakutia). Transmission …

Peridotite xenoliths and diamonds from kimberlites represent an important source of
information about the composition of the continental lithosphere at depths exceeding 120 …

Abstract Shallow (garnet-free), depleted cratonic mantle, occurring as xenoliths in
kimberlites and alkaline basaltic lavas, has a high Mg#(100× Mg/(Mg+ Fe)> 92) and is poor …

A genetic relationship between diamond and subcalcic Cr-pyrope garnet, both being
produced by a metasomatic process, can be inferred from the sampling patterns of …
