Gottardiite, a new high-silica zeolite from Antarctica: the natural counterpart of synthetic NU-87
Gottardiite was discovered in the Jurassic Ferrar dolerites of Mt. Adamson (Northern Victoria Land, Antarctica). The new zeolite occurs as subparallel aggregates of transparent pseudo-hexagonal lamellae. The mineral is orthorhombic, space group Cmca, with a=13.698(2), b=25.213(3), and c=22.660(2) Å...
