Dendritic Limestone

Dendritic Limestone is a sedimentary rock characterized by the presence of dendritic patterns, which are branching, tree-like formations. These patterns are typically created by the deposition of iron or manganese oxides within the limestone. The limestone itself is composed primarily of calcium carbonate, often formed from the accumulation of marine organisms' shells and skeletons. The dendritic patterns are usually black or brown and contrast with the lighter color of the limestone, creating visually striking patterns. The formation of these dendrites occurs when mineral-rich fluids seep through the rock, and the minerals precipitate out in these characteristic branching forms.
