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

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 …

Since first being discovered in India over 2000 years ago, the most striking and universally
recognized shape of an uncut diamond is the octahedron. This shape was revered from …

Ophiolites, which represent segments of oceanic lithosphere obducted onto the continental
crust, provide an important window into processes such as continental rifting, mantle …

Because of the great potential for zircon to provide insights into crustal melting and
evolution, much work has been done to develop tools to interpret its trace element …

Diamond‐hosted majoritic garnet inclusions provide unique insights into the Earth's deep,
and otherwise inaccessible, mantle. Compared with other types of mineral inclusions found …

The discovery of diamonds in metamorphic rocks of continental affinities occurred shortly
after the discovery of coesite in similar rocks. These important discoveries led to a revolution …

This chapter reviews the systematics of partial melting of mantle lithologies–like peridotite
and eclogite–in the presence of carbon dioxide. It discusses the composition of mantle …

The enigmatic appearance of cuboctahedral diamonds in ophiolitic and arc volcanic rocks
with morphology and infrared characteristics similar to synthetic diamonds that were grown …

Geophysical investigations and laboratory experiments provide strong evidence for
subduction of ancient oceanic crust, and geological and mineralogical observations suggest …
