The Moeraki Boulders


There are many anomalous objects buried in mountains, drowned in oceans or scattered across the landscape that are not adequately explained through conventional theories. 

40 kilometers south of Oamaru, New Zealand, is a beach where hundreds of calcium carbonate spheres have fallen out of a cliff face and rolled down into the water. They range in size from small nodules to giant balls over 4 meters in diameter. Said to be the result of slow growth around a nucleus, the spheres are referred to as “concretions” and are thought to be the result of tiny amounts of mineral precipitation taking place over 65 million years.

The Moeraki Boulders come from within a hillside that has been cut into by weathering. The various mineral layers are composed of mudstones and the nodules appear to have grown in place. The layers often surround them like nacre surrounds a foreign object to form the pearl in an oyster, yet the spheres are not part of the layers. If the surrounding material is dug away, the stone balls will fall out of their cavities because they are not attached to the inner wall.

Glassified spherules, created by C. J. Ransom in his VEMASAT laboratory, prove that lightning strikes might be a way by which stone eggs form. When NASA reported the discovery of “blueberries” on Mars, Dr. Ransom shot rock dust and soils with high voltage electric discharges. His results look remarkably similar to the Martian blueberries and to other such accumulations of stone balls on Earth.

Electric arcs of great power will smash matter into the center of a vortex and crush it into spherical shapes. It may also melt the material to a greater or lesser degree. Because of these “z-pinch” zones of compression, several kinds of “stone ball” might result and they will be composed of different substances, depending on their location.


For example, there are Moqui balls – iron spheres with sandstone cores, cannonballs, blueberries, thunder eggs, Apache tears and geodes. Many of them are hollow inside. What else besides electrical compression can account for the variety of substrate, the often-pressurized interiors of the spherules or the fact of their spherical shape in the first place? If the stones formed in place due to precipitation, they would be domes with flat bottoms. If they were in motion when they formed, they would be lozenge-shaped, like river rocks, or bullet-shaped – either way, they would not retain a rounded shape.

It seems likely that the Moeraki Boulders were left by giant electric arcs as they passed through the southern landscape of New Zealand, excavating the canyons, uplifting the stone tors and creating many other unusual geological formations there.
