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 …

Biotite (sensu lato) is a widespread rock‐forming mineral in magmatic rocks that can be
stable in a broad range of pressure and temperature, but appropriate biotite thermometers or …

After decades of low but continuing activity, applications of machine learning (ML) in solid
Earth geoscience have exploded in popularity. This special collection provides a snapshot …

Subduction related to the ancient supercontinent cycle is poorly constrained by mantle
samples. Sublithospheric diamond crystallization records the release of melts from …

The nature and cause of deep earthquakes remain enduring unknowns in the field of
seismology. We present new models of thermal structures of subducted slabs traced to …

Kimberlite-borne xenolithic eclogites, typically occurring in or near cratons, have long been
recognized as remnants of Precambrian subducted oceanic crust that have undergone …

Sublithospheric diamonds and the inclusions they may carry crystallize in the
asthenosphere, transition zone, or uppermost lower mantle (from 300 to∼ 800 km), and are …

The major-element chemical composition of garnet provides valuable petrogenetic
information, particularly in metamorphic rocks. When facing detrital garnet, information about …

Clinopyroxene major and trace element compositions document their physicochemical
evolution and have been widely used to detect mantle metasomatism. Classical methods …
