RM1713   Adularia (K Feldspar variety)

Val Giuv, Tavetsch, Vorderrheintal, Grisons, Switzerland

A glassy, translucent to transparent, very sharp, colorless adularia interpenetrated crystals from this classic Swiss locality. Green chlorite has nicely dusted and accented this excellent piece, which is complete all-around and is essentially pristine, except for contacting at the base. An old specimen.
Val Giuv is very rich in Alpine-type fissures, in particular, the Giuv syenite. Pockets are unevenly distributed and are concentrated along the southern boundary of the Giuv syenite rock body. Alpine-type fissures also occur in the aplite dikes but differ slightly in their paragenesis (beryllium minerals like milarite only occur in and around aplites).


Size: 6.5 x 6 x 5.5 cm.
Found in 1970's

Ex. L. Daunis (Barcelona)
