z1751 - Large, perfect tetranatrolite balls till 2 cm . The relationship between tetranatrolite and Gonnardite is still under discussion from this locality. size 4 x 3 x 3 cm
In the mid-1970s a cavern encountered on the 430-meter level of the X orebody, was encrusted with botryoidal and stalactitic vanadinite. SEM investigation has shown alternating layers of dark vanadinite with narrow layers of yellow descloizite. An extremely rare, unique occurrence . The descoizite is fluorescent under LW UV. Size 8x6x3 cm
