Perovskite is recognized by its branching arborescent, or dendritic form. The 1.0 mm cluster shown here is a close view of the tip of one such form. The perovskite is associated with nepheline crystals and acicular apatite. (Not shown in photo.) Photomicrograph © Saul Krotki 2003. Robert Meyer Collection.
