[Rockhounds] ‘Fountain of diamonds’ erupts from ground due to tectonic plate movement

[Kreigh Tomaszewski]

Researchers have discovered a pattern where diamonds explode from deep
beneath the Earth’s surface in huge, volcanic “fountains”.

Diamonds form approximately 150 kilometres deep in the Earth’s crust and
are brought to the surface very quickly in eruptions called kimberlites,
travelling at between 18 and 133 kilometres per hour.

Researchers noticed kimberlites occur most often during significant
disruptions among tectonic plates. After analysing the ages of kimberlites
and the degree of plate fragmentation occurring at those times, scientists
now believe the break-up of supercontinents is what causes these huge,
diamond eruptions.
