A dendrite is a crystal habit, wherein the crystal exhibits a branched chain growth. The term is used in crystallography and geology. The term dendrite is derived from the Greek word dendron (δενδρον), which boom means. Usually the dendritic crystal form is associated with fossils. Dendrite is formed naturally between fissures in rock. Some variants of manganese oxides and hydroxides, which often show a dendritic growth pattern: birnessiet (Na4Mn14O27 · 9H2 O) corona diet (PBMn8O16) cryptomelaan (KMn8O16) holla diet BaMn8O16) romanechitet ((Ba, H2O) Mn5O10) todorokiet ((Ba, Mn, Mg, Ca, K, Na) 2Mn3O12 · 3H2O) and others. In crevices of rock quartz develops a three-dimensional shape of dendrite with moss agate is formed. A similar phenomenon is known in other fields as arborescentie.
