... of the apatite supergroup. It occurs in skarn from the Malmkärra iron mine, Norberg, Västmanland (one of the Bastnäs-type deposits in Sweden), associated with calcite, dolomite, magnetite, lizardite, talc, fluorite, baryte, scheelite, gadolinite-(Nd) and other REE minerals. Fluorbritholite-(Nd) forms anhedral...

... experiments. Fluorbritholite-(Nd) was found on a boulder in the dumps of the Malmkärra Mine in Sweden. The Malmkärra mine ( Geijer and Magnusson 1944 ) started Fe-ore operations in 1664 and stayed open until the mid-1930s. This area of Sweden is well known for rare earth element minerals. Ytterby is ~150...
