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 ... Burial histories of septarian concretions from the Eocene London Clay and the Jurassic Kimmeridge Clay show that fracturing can form under as little as 50 m of sediment.

Septarian concretions (we prefer concretions to nodules, since the term concretion is generally used for regular and nodule for irregular diagenetic bodies: Pettijohn, 1975) are characterised by two sets of fractures, a concentric set and a radial set (Austin, 1986; Fig. 1).
