The Moeraki Boulders on Koekohe Beach are certainly intriguing. They lie on the beach for us to appreciate thanks to the erosive impact of wave action.
The boulders are riddled with large cracks called septaria that radiate outward from a hollow core lined with calcite crystals. The processes that created septaria within the boulders remain a mystery.
The composition of the Moeraki Boulders is virtually identical to septarian concretions that have been found in sedimentary rocks elsewhere in New Zealand, in the Kimmeridge and Oxford Clays of England, and at many other locations worldwide.
