3-Billion-Year-Old Klerksdorp Spheres Found in Ottosdal, South Africa.





Miners and rockhounds working in a mine near Ottosdal, South Africa have collected mysterious metal spheres from pyrophyllite deposits. Known as Klerksdorp spheres, these are small, spherical or disc-shaped, and range from dark reddish brown to dusky red in color. The spheres range from 0.5 to 10 centimeters in size, with three even latitudinal grooves around them. What is strange about the discovery is that although most of the remarkable samples of these spheres appear to be manufactured, they have, in fact, been dated to 3 billion years ago.

Extremist groups believe that these spheres are artifacts from ancient civilizations; however, geologists explain that Klerksdorp spheres are actually concretions formed from the natural process of the precipitation of volcanic sediments, ash, or both. Even the latitudinal ridges and grooves exhibited by Klerksdorp spheres are also natural. The same characteristics are also observed in the Navajo Sandstone of southern Utah known as ‘Moqui marbles’, the carbonate concretions found in Schoharie County, New York, and in concretions found in Australia.

False claims were also made but later on disproved after close examination of the spheres. One claim said that testing by NASA found that the spheres were ‘perfectly balanced’ while another stated that the spheres were manufactured from a metal ‘harder than steel.’

Specimens of the Klerksdorp spheres are housed in Klerksdorp Museum in Klerksdorp, a city about 70 kilometers away from Ottosdal. The discovery of the spheres is another addition to the many breathtaking wonders of the world.
