Tiny pyrophyllite spheres from 3 billion years ago
Found in nearly three-billion year-old mined deposits of pyrophyllite at Ottosdal, near Klerksdorp in South Africa, the Klerksdorp “Spheres” actually range from roughly spherical, through badly squashed, to disc-shaped. Some of them are intergrown in groups. Much of the woo hinges on the false claims that the objects are perfectly spherical,
Whenever its from out of space or a creation of Alien ,they all agree its creation of someone . Its may be the alien , the mother nature or Human . A three billion years old object the beauty in the eye .
Geological explanation of their origin
Various professional geologists agree that the Klerksdorp spheres originated as concretions, which formed in volcanic sediments, ash, or both, after they accumulated 3.0 billion years ago. Heinrich argues that the wollastonite nodules formed by the metamorphism of carbonate concretions in the presence of silica-rich fluids generated during the metamorphism of the volcanic deposits containing them into pyrophyllite. It was also argued that the hematite nodules represent pyrite concretions oxidized by weathering of near surface pyrophyllite deposits. Below the near-surface zone of weathering, which has developed in the pyrophyllite, pyrite concretions are unaffected by weathering and, thus, have not been altered to hematite. The radial internal structure of these objects is a pseudomorph after the original crystalline structure of the original carbonate or pyrite concretion.
Both Cairncrossnd Heinrich argue that the grooves exhibited by these concretions are natural in origin. As proposed by Cairncross,the grooves represent fine-grained laminations within which the concretions grew. The growth of the concretions within the plane of the finer-grained laminations was inhibited because of the lesser permeability and porosity of finer-grained sediments relative to the surrounding sediments. Faint internal lamina, which corresponds to exterior groove, can be seen in cut specimens. A similar process in coarser-grained sediments created the latitudinal ridges and grooves exhibited by innumerable iron oxide concretions found within the Navajo Sandstone of southern Utah called “ Latitudinal grooves are also found on carbonate concretions found in Schoharie County, New York. The latitudinal ridges and grooves of the Moqui marbles are more pronounced and irregular than seen in the Klerksdorp (Ottosdal) concretions because they formed in sand that was more permeable than the fine-grained volcanic material in which the Klerksdorp (Ottosdal) concretions grew
Very similar concretions have been found within strata, as old as 2.7 to 2.8 billion years, comprising part of the Hamersley Group of Australia. The Australian concretions and the Klerksdorp spheres are among the oldest known examples of concretions created by microbial activity during the diagenesis of sediments
Conspiracy Theory :
An oft-repeated claim is that testing by NASA found the spheres to be so precisely balanced that they concluded that they could not have been constructed on Earth, but would have required a zero-gravity environment. Other than a circulating image of an unverifiable letter there appears to be no record whatsoever of a NASA investigation of the Klerksdorp objects (but of course, if you’re into that sort of thing, the absence of records is proof of the “”).
