Meteorites

Beckettite is a relatively new mineral, approved in 2015 and to date reported only from the type locality.

Localities

At the type locality, the Allende meteorite, Pueblito de Allende, Chihuahua, Mexico, beckettite is a refractory (heat resistant) mineral, occurring as micrometer-sized grains intergrown with hibonite and perovskite, and surrounded by secondary grossular, anorthite, coulsonite, hercynite and corundum. It occurs within highly altered areas in a vanadium-rich inclusion from the carbonaceous chondrite.
Beckettite is a surrounded by primary high-temperature mineral resulting from igneous crystallisation of a vanadium-rich melt, together with vanadium-bearing hibonite, perovskite, burnettite, spinel and paqueite (Meteoritics & Planetary Science, 56 (in press)).
