SEPTARIAN CONCRETIONS

Kabardino-Balkaria, Russia

Septarian concretions are unique rock formations characterized by their cracked or geometric patterns, often filled with minerals like calcite, aragonite, barite, and sometimes pyrite, encased in a hard outer layer of limestone or mudstone.

These formations occur in sedimentary rocks, typically originating in tranquil marine environments where an organic nucleus, such as a deceased marine creature or shell, gets swiftly enveloped by sediment.
