Riddarhyttan, Sweden033
Previous | Home | NextThis was the valuable present given to us found by our guides earlier at the Bastnäs talus slopes: a beautiful crystal of bastnäsite, a rare earth carbonate. The red crystal of bastnäsite, on the side of the specimen towards the viewer, is marked with a copper tag placed there by Bengt. We analyzed the crystal when we returned to the U.S. and found it to contain 26% lanthanum, 29% cerium, and 6% neodymium, with lesser amounts of other light rare earths.
