Septarian is a mixture of orock, mineral, and organic materials. Septarian generally consists of yellow calcite, brown aragonite, grey limestone, and barite. Septarian concretions are the result of volcanic activity when mud and organic matter are trapped and sealed by pressure intense drying in a cemented state. As septarian never forms the same, each sink is truly one of a kind.
