A concretion is a hard, compact mass of rock that often forms around decaying organic matter. In the case of septarian nodules the concretions formed around decaying sea-life in a marine environment.(The name septarian originates from the term "little walled," referring to the raised cracks in the outside of some concretions.) In these concretions the fine-grained concretion body (usually composed of calcite, CaCO 3) is cut by a radiating network of fractures filled with coarsely crystalline calcite and other minerals (Figs. 4 and 5). The ...

A concretion is a hard, compact mass of rock that often forms around decaying organic matter. In the case of septarian nodules the concretions formed around decaying sea-life in a marine environment.Syneresis within the concretions can cause septarian fractures to occur. Secondary minerals may precipitate and fill voids left by decaying tissues. Tidal laminae are often compressed around concretions, suggesting that compaction of the sediment occurred after lithification of the proto-concretion (Kuecher et al. 1990). Based on Baird et al.

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 ...
