System:TetragonalColour:Black
Hardness:6 - 6½
Name:Named in 1863 by A. E. Nordenskiold after an ancient Finnish divinity.


A group name for Tapiolite-(Fe)-Tapiolite-(Mn) Series.

The original iron-dominant tapiolite material came from "near Kulmala Farm", Sukula, Tammela, Etelä-Suomen Lääni, Finland.

Classification of Tapiolite

Hey's CIM Ref.:18.1.46

Occurrences of Tapiolite

Geological Setting:Granite pegmatite

Physical Properties of Tapiolite

Lustre:Adamantine, Sub-Adamantine, Metallic, Sub-Metallic
Diaphaneity (Transparency):Opaque
Colour:Black
Hardness (Mohs):6 - 6½
Fracture:Irregular/Uneven
Density (measured):7.35 - 7.37 g/cm3

Crystallography of Tapiolite

Crystal System:Tetragonal
Class (H-M):4/mmm (4/m 2/m 2/m) - Ditetragonal Dipyramidal
Morphology:Short prismatic [001] or equant, with {001}, {100}, {110} and {113} usually well developed. Untwinned crystals often appear monoclinic or orthorhombic due to distortion.
Twinning:On {013}, very common. The twins are distorted by elongation on [0_31] (parallel to an adjacent pair of 113 faces) and simulate orthorhombic symmetry. Also twinned on {101}, rare.
