Mutinaite, a new zeolite from Antarctica: the natural counterpart of ZSM-5
Mutinaite is the third new zeolite from Ferrar dolerites at Mt. Adamson (Northern Victoria Land, Antarctica). The mineral occurs as subspherical aggregates of tiny radiating lath-like fibers or as aggregates of transparent, colorless to pale-milky, tiny tabular crystals; it has vitreous luster, whit...

Mutinaite is the third new zeolite from Ferrar dolerites at Mt. Adamson (Northern Victoria Land, Antarctica). The mineral occurs as subspherical aggregates of tiny radiating lath-like fibers or as aggregates of transparent, colorless to pale-milky, tiny tabular crystals; it has vitreous luster, white streak and good {100} cleavage. Mutinaite is brittle with measured and calcd. d. 2.14(3) and 2.17 g/cm3, resp. Optically, it is biaxial neg. with ns α = 1.485(2), β = 1.487(2) and γ = 1.488(2). The orientation is X = b, Y = a, Z = c. Mutinaite is orthorhombic with a = 20.223(7), b = 20.052(8), c = 13.491(5)Å, space group Pnma.
