Septarian structures occur in concretions or concretionary sheets ... tauke travelfoldsofhonor orgcraigslist canby oregon Septarian concretions or septarian nodules are sometimes called Dragon Eggs. They form primarily in an ocean setting just below the sediment surface through a series of steps. Some sort of nucleus, such as a fossil, is buried in the sediment. Fine grained calcite mud precipitates around this nucleus and a hard mud ball is formed. The longer the ocean level stays relatively constant, the bigger ... is limestone organic Concretion. A concretion is a volume of sedimentary rock in which a mineral cement fills the porosity (i.e. the spaces between the sediment grains). Concretions are often ovoid or spherical in shape, although irregular shapes also occur. The word 'concretion' is derived from the Latin con meaning 'together' and cresco meaning 'to grow'.In septarian concretions, the original cementing mineral was clay, which contains water.
