2023 ± 4 million years ago a giant Asteroid hit the earth surface, of what today is South-Africa. The kinetic energy set free, when the Asteroid traveling at cosmic speed was abrupt stopped, was transferred into a gigantic Explosion. The Impactor and surrounding earth rocks vaporized immediately. One of the biggest impact structures known on earth was created. The rim to rim diameter of the Vredefort astrobleme is 160km. The impact affected earth surface has even a diameter of 300km.
This sphere is made from the impactite type impact-melt-breccia. Dark gray to black melt with shocked and unshocked granite and gneiss fragments.
