Initially, it may seem extremely daunting to be sitting in front of several thousand carats of
small diamonds, knowing that the likelihood of finding a diamond with a meaningful …

Earth's carbon, derived from planetesimals in the 1 AU region during accretion of the Solar
System, still retains similarities to carbon found in meteorites (Marty et al. 2013) even after …

Kimberlite magmatism has occurred in cratonic regions on every continent. The global age
distribution suggests that this form of mantle melting has been more prominent after 1.2 Ga …

Mineral inclusions encapsulated in diamonds are the oldest, deepest, and most pristine
samples of Earth's mantle. They provide age and chemical information over a period of 3.5 …

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 …

Geothermobarometric calculations for a worldwide database of inclusions in diamond
indicate that formation of the dominant harzburgitic diamond association occurred …

Diamonds and a wide range of unusual minerals were originally discovered from the
chromitite and peridotite of the Luobusa ophiolite along the Yarlong–Zangbu suture zone in …

ABSTRACT Views of the Superior Province as an accretionary orogen have developed over
the past two decades as a result of recognition of numerous distinct protocontinental and …

Ophiolites are a newly documented host of diamonds on Earth. Abundant diamonds have
indeed been separated from peridotites and chromitites of ophiolites in China, Myanmar …

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