Type Occurrence of Scainiite
General Appearance of Type Material:
Acicular crystals, elongated [010], black in colour with bluish metallic luster. The bluish colour apparently arises from a superficial very low hydrothermal alteration of the crystals.
Place of Conservation of Type Material:
Museo di Storia Naturale e del Territorio, Pisa University, Italy Catalogue numbers: 15521, 15522, 15523.
Musée de l'Ecole des Mines de Paris, France.
Musée de l'Ecole des Mines de Paris, France.
Geological Setting of Type Material:
Late extensional calcite veins embedded in the dolomitic limestones.
