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.

Septarian concretion. Septarian concretions have been recognized in many sedimentary units spanning nearly all ages. Although they exhibit a bizarre structure, their widespread occurrence makes septarian concretions more than just simple geologic curiosities. The tapering veins, or "septaria", within these concretions are often filled with complex, relatively late-stage (post-concretion body) isopachous rim and ...

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.
