| Scolecite is monoclinic and typically occurs as slender prismatic crystals with a squarish cross section. |
| Whereas monoclinic pyrrhotite is ferrimagnetic, the hexagonal variety is antiferromagnetic. |
| It has no cleavage or parting and is biaxial positive, nonpleochroic, and monoclinic. |
| Minute, monoclinic acanthite crystals on lead-hillite and silver are reported from the Mammoth-St. Anthony mine, Pinal County. |
| Crystallizes in scalelike monoclinic forms, but usually forms compact claylike masses. |
| These are, in order of decreasing symmetry, the cubic, hexagonal, tetragonal, trigonal, orthorhombic, monoclinic, and triclinic systems. |
