| Lithology description: The beds frequently contain accumulated biodetritus, mainly Echinodermata-debris and Bivalve-shell. The marly claystone is subdivided through layers of pyrite nodules, accumulations of limeconcretions and finley distributed Bivalve-(Bositra)-shell, forming a quite disturbed sedimentsuccesion. | |
| Environment: | offshore |
