Large Sikhote-Alin Meteorite Shrapnel
Located in London, GB
Sikhote-Alin Meteorite Shrapnel, Iron, Coarsest Octahedrite
“This chunk of twisted metal shows the extreme force of the low altitude air burst which exploded the main mass, causing shockwaves which collapsed chimneys, shattered windows and uprooted trees. Sonic booms were heard more than 300 kilometres away and a 33-kilometre long smoke trail persisted in the sky for several hours.” - Dr Alan E. Rubin, PhD Department of Earth, Planetary, and Space Sciences, UCLA
Dating back to the formation of the solar system, some 4.55 billion years ago, Sikhote-Alin meteorites are the best preserved of all known iron meteorites. This extremely aesthetic specimen is a beautiful example of the so-called shrapnel type. It is the result of a powerful secondary explosion which occurred close to the ground, producing a wonderfully scarred and sculptural appearance, with torn and jagged edges and delicate flow lines. On the morning of 12 February 1947, an enormous iron meteor passed through the Earth’s atmosphere, exploding over the Sikhote-Alin mountains in South-eastern Russia...
