RM1747   Metatorbernite and quartz

Calo, Vimianzo, A Coruña, Galicia, Spain

Group of very sharp metatorbernite crystals, with an intense green grass color, showing the combination of the first and the second order dipyramids, truncated by pinacoidal faces. Its intense color gives a nice contrast with the white quartz matrix. Large open cast mines ans small prospects of kaolinite with some quartz veins in which torbernite crystals have been found. We could say that this locality is included in the most worldwide important torbernite localities due to the crystal quality, size and multiple habits.


Size: 4.5 x 2.7 x 2.2 cm.
Main crystal: 3 mm.
Found in ca. 2008

Presents radioactive activity.
