RM2528   Carbonate-hydroxylapatite, montgomeryite and goethite

Elvira mine (Rocabruna mines), Bruguers, Gavà, Barcelona, Catalunya, Spain

Many years ago, these crystal aggregates were classified as brushite, but later analysis indicated that it was hydroxylapatite with carbonate groups. Fluorapatite is not common in Bruguers. These globular aggregates are disposed on an upholstered matrix with bright green microcrystals of montgomeryite. The matrix is goethite. From the J. Astor collection, formerly col. Jordi Pi, well-known nature and geological landscape photographer and mineral collector (Barcelona).


Size: 4.2 x 4.1 x 2.9 cm.
Found in ca. 1980.
