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 …

Kimberlites are volcanic rocks enriched in CO2 and H2O and derive from the deepest-
sourced melts (up to 300 km) that reach Earth's surface. The mantle processes that generate …

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 …

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 …

Micro-inclusions in diamonds from Zaire and Botswana differ in composition from the more
common large inclusions of the peridotitic or eclogitic assemblages. These sub-micrometre …

There are six distinct classes of gold deposits, each represented by metallogenic provinces,
having 100's to> 1000 tonne gold production. The deposit classes are:(1) orogenic gold;(2) …

Fluid-inclusions in fibrous diamonds from Jwaneng (Botswana) contain water, carbonates,
silicates, apatite, and CO 2. Average compositions of fluids trapped in individual diamonds …

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

This chapter is devoted to the carbon and nitrogen stable isotope compositions of terrestrial
diamonds with a strong focus on monocrystalline diamonds formed in Earth's mantle. The …
