Klerksdorp sector , find inside pyrophyllite deposit mine in South Africa , are weird . take care like diminutive ancient cricket balls , with seam - similar lines around their midriff , it ’s easy to see why they became the depicted object of confederacy theories postulate aliens and ancient , forgotten civilization .
Inarticles in the 1980s , they were speculated to be made by " a mellow civilisation , a pre - flood civilization about which we know virtually nothing " , while the same museum curator who say this claimed that the spheres rotated of their own accord while engage in a " vibration - costless " display case .
fake - scientist claim that the spheres could only be cook up , despite being found in3 - billion - year - old rock , while even impostor - er scientist believed them to beproof of alien .
The claims about the sphere fascinate the tending ofgeologist Bruce Cairncross in 2006 , who write that he had been amused by an clause that described them as " mystery sphere of influence " , and by one programme ’s selection to have a psychical examine the Isidor Feinstein Stone , declaring them to be the clay of an ancient spaceship .
Cairncross offered up a rational account for the spheres , find in a geological formation known as the Dominion Group . The feature of speech is made of empire , with layers of volcanic lava that were deposit on top . After a lot of atmospheric pressure and heat , the level of volcanic rock became pyrophyllite , the case in which the Klerksdorp spheres were found .
The spheres are bang as conglutination : spherical , oval-shaped , or pumpkin-shaped object made of different mineral to the host careen , and are somewhat unwashed , with thousands having been found around the world . They are often retrieve in fine - grain rocks , like pyrophyllite , as it allows for the movement of weewee .
" They form by hastiness from an aqueous solution and consist of minerals crystallized in the host rock,“Cairncross explained .
The welkin are spherical ( or slightly off - globose ) as they organise around a tiny metric grain of mineral in a solution containing iron , atomic number 20 , and other elements .
" Because the server rock is evenly textured all round the growth of the concretion takes place , nonsensitive in all focussing , as a 360 - degree , three - dimensional arena , " Cairncross writes , impart that if the liquid is prompt or the John Rock surrounding it is not the same consistency in all direction , the shape can become distorted .
The lines across the area are due to impression from the master of ceremonies rock , which was built up in layers over a foresighted , tenacious time , leaving the layered outcome .
Meanwhile , the mystery of why the sector supposedly spun " on its own " was explained by the curator of the Klerksdorp Museum , after which the spheres are named .
" Some years ago I put the ball back to its original position ( on a crank shelf ) during a journalist ’s visit and he tried to make a sensation of it , " Mr R Marx explained . " It is quite instinctive that it will rotate a bit as it is round and we have many earth tremors due to ( gold ) mining activities . "
