| 説明 | Set on paleozoic granite rock this crater has a diameter of 380M and depth of 31M and is the largest meteoritic crater in Chile. It is estimated that the meteorite that formed the crater had a diameter of 13 meters and impacted against the ground at a speed of 54.000 MK/H. The shock wave produced by the impact was equivalent to 2 Hiroshma Atomic Bombs and generated temperatures higher than 1.400 C capable of vaporizing the meteorite along with local rocks which were ejected over the crater rim then solidifying and forming the impactites. A glassy vesicular aggregate composed of minerals from the local rock and small nodules belonging to the meteorite.(click next to continue) |
