Septarian concretion
One of the lesser understood features of concretions is a variety of heavily fractured concretions, named septarian concretions. By taking a new approach in the study of septarian fracture patterns, it is possible to connect the episode of fracturing to a wider tectonic event and better understand how and when they fractured.Chapter Jan 1978 Kitty L.
