The US used to be leading rare earth producer in 1990, but the situation has changed long ago. In 2018, Beijing increased rare earths mining by 15,000 tons to 120,000 tons, while the US produced just 15,000 tons in total. China holds 44 million tons of the elements if its reserves, while the US just 1.4 million tons.


The behaviour of rare earth elements (REE) during fluid-rock interaction in mid-crustal shear zones has received little attention, despite their potential for mass balance calculation and isotopic tracing during deformation. In this study, several cases of large REE mobility during Alpine fluid-driven shear zone development in the pre-Alpine granitic basement of the Mont Blanc Massif are ...
