Caryopilite
A variety of Minerals
What is Caryopilite?
Caryopilite is reddish-brown to tan in color naturally; in thin sections, it is light brown to yellow. The mineral occurs as tabular pseudohexagonal crystals, commonly as rosettes, up to 4 millimeters (0.16 in). It can also be stalactitic, reniform with a concentrically radiating structure, or have massive habit. The mineral forms as a product of metamorphism in manganese-bearing minerals. Caryopilite has been found in association with brandtite, calcite, gonyerite, jacobsite, lead, manganoan calcite, rhodonite, sarkinite, tirodite.

Key Characteristics
Composition of Caryopilite
Caryopilite consists of triangular islands formed by tetrahedra rings coordinated with sheets containing octahedrally coordinated manganese. The crystal structure shows some short-range order, but linkages between islands are fully disordered. Thus, no unit cell can truly be defined.
