Clerksdorp balls

Clerksdorp balls or South African carved spheres were discovered in rock of Precambrian origin, which is about 2,8 billion years old near the city of Klerksdorp in North-West Province of South Africa. This is more than 200 metal balls of different diameters: from very small diameter of 2,5 cm to the size of cricket balls (about 10 cm). Exactly the same carved spheres were discovered in quarries near the town of Otgosuaul, in the western part of the Transvaal province.

The Clerksdorp balls found were of two types: one of bluish metal with white specks, others were hollow balls filled with white matter

The Clerksdorp balls found were of two types: one of bluish metal with white specks, others were hollow balls filled with white matter. Some of the spheres have a fibrous structure with an inner shell around it, which is so hard that it can not be scratched by steel.

After the discovery of circular grooves on some balls (and three parallel grooves on one of them), the scientists came to the conclusion that the Clerksdorp balls are the work of human hands. This fact says that a highly developed life existed on our planet hundreds of millions of years before the first human beings appeared on it.

Paul Heinrich turned to geologists for help, who suggested that the Clerksdorp balls consist of pyrite, which has a bronze-yellow color, and goetite, yellow-brown mineral, which is an oxide of iron. Heinrich believes that the clerksdorp balls were formed as a result of metamorphic processes from clay or volcanic ash. He rejects the fact that some spheres have a blue color, on the grounds that such information was submitted by the newspaper, which, he claims, printed articles of a very dubious quality.

Other researchers believe that the Clerksdorp balls are limonite nodules, a kind of iron ore. But such formations are usually found in groups that "stick together like bubbles of soapy foam". The Klerksdorp spheres are isolated, spherical, and, moreover, they are too hard to consist of limonite.

To the end, their composition has not been studied. Some sources claim that the Clerksdorp balls are made of nickel-iron alloy, meteorite origin, and that fibrous material inside some of them in the air turns into dust.

Until now, there is no explanation for grooves on them. If the Clerksdorp balls are of natural origin, then the grooves were applied after they were removed from the rock. But how and what they were applied to a subject that was close in hardness to diamond? In another case, they are inscribed on the spheres by intelligent beings 2,8-3 billion years ago, and who these creatures were, one can only guess.

The origin of the Clerksdorp balls became even more mysterious after Rolf Marks, director of the museum in Klerksdorp, where several South African carved spheres are located, reported that one of them, closed in a glass case and isolated from external sources of radiation, suddenly by itself began to rotate around its axis...
