RM1713 Adularia (K Feldspar variety)
Val Giuv, Tavetsch, Vorderrheintal, Grisons, SwitzerlandA 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
