Septarian concretion
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. By relating episodes of septarian fracturing to times of rapid burial, the timing of diagenetic cement formation can be constrained.
Oct 6, 2009 · Septarian Concretion Formation. Septarian concretions, also known as septarian nodules, are mineral deposits that have a different composition than the host rock. Often the concretion forms by accretion when silica or another mineral begins to form a nodule within the host rock. The nodule may grow around grain of sand or a plant or animal ...
Septarian structures have attracted debate since the late 19th Century, when the accepted hypothesis was that they formed by shrinkage of the interior parts of the concretion. This idea has attracted many proponents since that time involving increasingly more complicated growth models ( Pratt, 2001 ).
