Summary

The Moeraki Boulders are geological marvels, exposed by erosion of sedimentary rocks laid down from 65 to 13 million years ago. They are formed by the gradual precipitation of calcite in mudstone over 4 million years. These spherical concretions are internationally significant for their scientific value and are a popular tourist attraction.
