Septaria - Natural minerals and crystals

Septaria is a particular geological formation, characterized by desiccation nodules developing within sedimentary raw rocks and minerals">rocks, mainly marls. These nodules, often rounded or irregular in shape, present a network of fractures filled with calcite or other minerals. The mineralogical composition of septaria is variable, but it generally includes calcite, aragonite and dolomite, as well as traces of other minerals such as quartz or pyrite. The formation of these nodules extends over long geological periods and involves several stages. septaria attracts great interest from geologists due to its complex formation and mineralogical diversity. The study of these nodules allows us to better understand the geological processes that took place in the past. In addition, septaria is used in various fields, particularly in decoration and jewelry. The most aesthetic specimens are cut and polished to create art objects or jewelry.
