Faulted layer of radiolarian chert


This is from the Chert Series Beds exposed on Mt. Lykaion near Megalopolis in the Peloponnesos. I collected it during the summer of 2009.  The fact that the specimen holds together even though it is full of faults is one of its remarkable features, …making it a ‘collectable.’

Age & Formation
Faults cutting and displacing radiolarian chert layer, Peloponnesos, Greece. Jurassic is age of original layer. Faulting took place during late Cretaceous and early Tertiary.
