Tapiolite

This page is currently not sponsored. Click here to sponsor this page.
Formula:
(Fe,Mn)(Ta,Nb)2O6
Colour:
Black
Lustre:
Adamantine, Sub-Adamantine, Metallic, Sub-Metallic
Hardness:
6 - 6½
Specific Gravity:
7.35 - 7.37
Crystal System:
Tetragonal
Name:
Named in 1863 by A. E. Nordenskiold after an ancient Finnish divinity.
A name for chemically unanalysed members of the Tapiolite-(Fe)-Tapiolite-(Mn) Series.

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

18 : Niobates and Tantalates
1 : Niobates and tantalates containing neither rare earths nor U

Physical Properties of TapioliteHide

Adamantine, Sub-Adamantine, Metallic, Sub-Metallic
Transparency:
Opaque
Colour:
Black
Hardness:
6 - 6½ on Mohs scale

Chemical Properties of TapioliteHide

Formula:
(Fe,Mn)(Ta,Nb)2O6

Crystallography of TapioliteHide

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.
