Its veins reach grades far in excess of any other rare earth deposits anywhere in the world, and the mineralisation is in the form of seams of almost pure bastnaesite/monazite. We have discovered these veins outcropping at surface over almost all of the 39km 2 mining permit, which tells us that the deposit contains a potentially vast quantity of highgrade ore. But more recent testing suggests ...Get Price

Abstract A sequence of amphibolite to granulite facies metasedimentary and mafic metaigneous rocks from the western Italian Alps has been analysed for rare earth elements (REE). In this sequence, the metasedimentary granulites have probably been affected by a melting event while the metaigneous granulites remained unaffected. Metasedimentary granulites have a less fractionated chondrite ...Get Price
