Elementary Crystallography
The orthopinakoid {100} is rarely seen, and a cross-section is therefore six-sided,
not eight- sided as in the pyroxenes. The prism angle is about 560. The
commonest terminations are the clinodome {011} and the positive hemi-
orthodome {101} ...

Cleavage: Very perfect parallel to the orthopinakoid. Also found massive, and
with broad cleavage surfaces. Colour: Greyish or greenish. Translucent to
subtranslucent Streak: Oolourless. Lustre. Pearly, but vitreous on cross-fractured
surfaces.

The mineral is somewhat concentrated into folia and porphyroblastic crystals up

that sections cut parallel to the schistosity exhibit numerous porphyroblasts,
