The Sikhote-Alin meteorite is the largest observed meteorite fall in modern history. It rained fireballs into the Sikhote-Alin Mountains in Eastern Siberia, Russia on February 12, 1947 at 10:38am. The meteorite was brighter than the sun and impacted the moutains with such an explosion it was felt over 100 miles away. Pieces were even found embedded in nearby trees! This meteorite is classified as an iron meteorite and is composed of 93% iron. If you have any questions, do not hesitate to ask me. If you purchase from me you should know that the authenticity of this meteorite is guaranteed! I am a member of the IMCA or the International Meteorite Collector's Association. This is an organization that is a check and balance of those who collect, trade and sell meteorites. You can only join this organization by having the utmost integrity. You must to have two references from existing members to get in and a good reputation. Members of this organization maintain a high standard by monitoring each others' activities for accuracy and honesty. It is every IMCA member's responsibility and pleasure to offer help and assistance to fellow members in order to ensure specimens are genuine. It is not wise to purchase meteorites on or other sources from those who are not IMCA members. This is a very tight-knit community made up of meteorite hunters, dealers, collectors, and scientists who look out for each other to make sure that the meteorites offered to the public are authentic and genuine. I encourage you to visit the IMCA website and get more information on what being a member means, and how your purchases from its members are guaranteed. IMCA Member #7446 Below is some information about this meteorite: It was a still, frosty, almost cloudless day on the morning of February 12th, 1947 in Eastern Siberia, when at 10:38 a.m. local time a bolid appeared in the sky, clearly visible in a full sunlight. It initially looked like a bright star, but soon turned into a dazzling fireball, which became slightly elongated. The Bolid rapidly crossed the sky north to south, leaving behind it a boiling dusty trail of the meteoroid particles. Then it passed out of sight, behind the hills in the Sikhote-Alin Mountains. During the flight, the bolid split into several parts, shich could be observed on the last visible segment of its trajectory. Several minutes after the bolid shine went away, local inhabitants heard loud bangs like explosions or a cannonade. Then followed a thunder and roaring rolled far over the taiga and resounded over and over in spurs of the Sikhote-Alin ridge. The most intense phenomena were reported by witnesses in villages situated along the ground projection of the meteoroid trajectoory. They told about doors swung, windows broken, and plaster falling out during the fall. Flame was breaking out of furnaces, ashes and smouldering brands flied out. Horses neighes, cows mooed, they broke loose and dsashed around. Dogs rushed under cover yelping, or ran away into the forest. Almost all witnesses asserted that the bolid's flight lasted only 4-5 seconds. It was observed over territory more than 600 kilometeres in diameter. The gieant trail of dust and smoke remained on the sky for the rest of the day! Gradually it was twisting due to strong air currents in the upper atmosphere. The trail disappeared only by the sunset. An artist named Medvedev witnessed the meteoroid flight and pictured it right away. Ten years later, in 1957, his painting was reproduced on a Soviet postal stamp. In two days, the fall location, had been determined by plane pilots who saw clearly marked fresh craters amidst untouched snow. Soon afterwards, a group of geologists arrived from Khabarovsk. They examined craters and holes and gathered the first specimens of the meteorite iron. Exploration of the fall site Regular expediations began to work on the site already at the end of April 1947, after the snow melted out. The region was throuroughly examined. Explorers found 20 craters of diameter more than 9 meters (the biggest one #1, was 26 meters inb diameter and 6 meters deep), and also 98 smaller craters and penetration holes, o.5 to 9 meters in diameter. Besides, they outlined the "scattering ellipse", that contained small pieces and stretched down north from the principle crater field, encircling an area of about 4 km by 12 km. This ellipse was a result of the meteroite falling apart during the flight. Smaller pieces which were losing speed sooner than the larger ones, fell down as a shower in the meteorites tail.

Two principally distinct types of specimen have been discovered. First, there are fragments, or shrapnel. These, of ragged shape, are shivers of the meteorite, occured as a result of the destruction of the large pieces (2-3 tons), which hit the ground at high velocities, formed craters, and broke into fragments that bounced off. Another type is complete individuals. These are probably the ones that broke off of the mass during the main descent. They show ablation and fusion crust. The surface was evaporized and eroded by the trip through the atmosphere. There feature is regmeglypts - or thumbprints - ablation cavities in the surface of the specimen.

The largest piece of the meteorite of weight, 1,745 kilograms, was excavated from crater #45 of diameter 3.5 meters at a depth of 4 meters. This is an excellent, individual specimen, oriented, with a distinct regmaglyptic surface and "fly lines". It is on display and the Fersman Mineralogical Museum in Moscow. Total mass of meteorite iron that reached the ground is estimated by various researchers as 70-100 tons. Offical data reports over 27 tons recovered to date. Technical data: Coordinates of the fall: 46 degrees 9.6 minutes North, 134 degrees 39 minutes East. Trajectory: Azmuth 20 degrees East of North; Altitude (decent angle to horizon) 38 degrees ; at the final segment 60 degrees . Structural Class: Coarsest Octahedrite. Chemical Class: Iron IIB ; Fe 93.32% , Ni 6.00%, Co 0.47% , Cu 0.03% , P 0.28% , S < 0.01% . Minerals composing the meteorite: Kamacite, taenite, plessite, schreibersite, rhabite, troilote, chromite.
