Pervasive closely spaced fracturing in radiolarian chert, Peloponessos, Greece


I collected this rock during the summer of 2008 in the Pindos fold and thrust belt of the Peloponessos near the village of Ano Karyes.  I like this rock because it keeps me quite humble as I try to think about all the factors and conditions that created such a fractured ‘mess’ of this rock.  And I puzzle over how it holds together without just falling apart in my hand.

Age & Formation
Radiolarian chert from within Chert Series Beds of Jurassic age, ~180 Ma., Peloponessus, Greece.
