System:TetragonalHardness:6 - 6½
Name:After an ancient Finnish divinity.


A group name for Ferrotapiolite-Manganotapiolite series.

The original tapiolite material came from Sukula, Tammela, Etelä-Suomen Lääni, Finland.

Physical Properties of Tapiolite

Hardness (Mohs):6 - 6½

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.
