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 …

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

Geological pathways for the recycling of Earth's surface materials into the mantle are both
driven and obscured by plate tectonics,–. Gauging the extent of this recycling is difficult …

Laboratory experiments and seismology data have created a clear theoretical picture of the
most abundant minerals that comprise the deeper parts of the Earth's mantle. Discoveries of …

The mineralogy and chemical compositions of inclusions in diamonds are the primary
source of information about the environment in which diamonds grow and help constrain the …

During the past two decades significant progress has been made in understanding the
origin and evolution of kimberlites, including relationships to other diamondiferous magma …

Earth's lower mantle most likely mainly consists of ferropericlase, bridgmanite, and a
CaSiO3-phase in the perovskite structure. If separately trapped in diamonds, these phases …

The science of studying diamond inclusions for understanding Earth history has developed
significantly over the past decades, with new instrumentation and techniques applied to …

Super-deep diamonds (SDDs) are those that form at depths between∼ 300 and∼ 1000 km
in Earth's mantle. They compose only 1% of the entire diamond population but play a pivotal …

A novel structure of calcium orthocarbonate Ca 2 CO 4-Pnma has been discovered using ab-
initio crystal structure prediction methods (AIRSS and USPEX) based on the density …
