Notes

  • Orthorhombic (orth): where each axis is of different length but the angle between each axis is 90°. (25% of known minerals).
  • Dome: an open form of facet (face) found in monoclinic and orthorhombic minerals.
  • Prism: a crystal that has a uniform cross section. In geometry, it is a solid that has two congruent and parallel faces (the bases) and whose lateral (side) faces are parallelograms.
  • Pinacoid: the face of a crystal that is parallel to two of the axes.
