Stratabound concretions consist ...A new hypothesis for concretion growth and septarian cracking argues that quasi‐rigid 'proto‐concretions' formed via binding of flocculated clays by bacterial extracellular polysaccharide substances (EPS). This provided rheological and chemical conditions for tensional failure, subcritical crack growth, volume contraction, calcite ...One particular type, called a septarian concretion or septarian nodule, contains numerous angular cracks that form a network, usually in a contrasting colour.
