The North China Craton (NCC) was originally formed by the amalgamation of the eastern
and western blocks along an orogenic belt at∼ 1.9 Ga. After cratonization, the NCC was …

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 …

Evidence of life on Earth is manifestly preserved in the rock record. However, the microfossil
record only extends to∼ 3.5 billion years (Ga), the chemofossil record arguably to∼ 3.8 Ga …

Abyssal peridotites are ultramafic rocks collected from mid-ocean ridges that are the
residues of adiabatic decompression melting. Their compositions provide information on the …

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 …

In 1794, the German physicist EFF Chladni published a small book in which he proposed
the extraterrestrial origin of meteorites. The response was skepticism and disbelief. In the …

Continents, especially their Archean cores, are underlain by thick thermal boundary layers
that have been largely isolated from the convecting mantle over billion-year timescales, far …

We present a new global thermochemical model of the lithosphere and underlying upper
mantle constrained by state of the art seismic waveform inversion, satellite gravity (geoid …

Diamond is not a common rock-forming mineral (an exception being “diamondite”; see
Jacob and Mikhail 2022, this volume) nor a common crustal mineral (the exceptions being …

The origin of cratonic diamonds is reviewed on the basis of nearly 5000 analyses of silicate,
oxide and sulphide inclusions in diamonds. Compositional fields are defined for common …
