Mina San Carlos, San Juan de Plan, Huesca, Aragón, España


Cobalt mine known since 1730, which was producing around 70 tonnes of cobalt ore a year towards the 18th and 19th centuries. The mineral was employed to get blue pigment, used in French and German ceramics industry. The latest operations of the mine were made between 1936 and 1945.

Most of the ore is included within by a carbonate horizon interlayered on top of Silurian black shales, that belongs to the autochthonous Palaeozoic units of Gavarnie nappe. This ore-bearing unit is extensively ankeritized and developed a roughly stratiform shape with a total length of 500 m and a maximum thickness of 2 m. The origin of this ankerite is clearly epigenetic as evidenced by investigations of contact relationships between the ankerite and the remaining Silurian limestones. Four stages of ore deposition can be distinguished: (I) Fe sulphides and sulpharsenides, (II) Co-Ni arsenides and sulpharsenides (Fig. 3E), (III) Co triarsenides, and (IV) a late Fe-Bi-Cu-(Co) stage.
