| "The morning of February 12, 1947...was clear over the Sikhote-Alin Mountains of eastern Siberia. These mountains lie in Siberia's Maritime Province on a narrow strip of land wedged between the Sea of Japan to the east and China to the west."...at 10:38A.M. ,a flaming fireball as large as the sun suddenly appeared in the cloudless sky. It was traveling from north to south and casting shadows and changing colors with red dominating, especially toward the end of the flight. Loggers, that were close to it, saw it split into several pieces before crashing beyond the trees with a huge explosion and a sound of tremendous "rolling thunder". The shock wave was felt 100 miles away, breaking windows along the way! The pieces landed within a 1.2 mile area as the main mass breakup occurred only 3.6 miles above the Earth. |

| Three geologists from the Geological Society in Khabarovsk landed 7 miles away from the site on February 21st, to begin to explore the region and locate the site. After 3 days of searching, they came upon the site filled with fragments of bedrock hurled out by the meteorite. Snapped branches were strewn into the snow and sand and clay were mixed into the snow. They counted 33 craters. Later, 122 craters and pits were found in total, with the largest being 85 feet across and nearly 20 feet deep! Further searching produced individuals that display excellent regmaglypt's (the deep pits and cavities on the exterior of meteorites produced by ablation of certain minerals in the meteorite as it passes through Earth's atmosphere), and also excellent pieces of "shield-shrapnel" (iron meteorite fragment showing a smooth, rounded exterior with flow lines extending to a distorted, jagged edge). We at the Nature Source offer both for your collection needs. Iron Meteorites:" Believed to be the core material from what most likely was another "planetary" type body; (or very large asteroid). The "crust" of that body would be the achondrites. Today, meteoriticists use a new chemical classification system that divides the irons into twelve groups based on the concentrations of trace elements. There are certain elements, the siderophiles, that have an affinity for iron (their atoms can readily bond with iron atoms as the iron crystallizes in a melt). These elements include nickel as the major element and several trace elements such as iridium, gallium, and germanium." Octahedrites: "most iron meteorites contain between 7 percent and 13 percent nickel. This nickel content results in mixtures of low-nickel kamacite and high-nickel taenite. The inter growth of these two alloys leads to a striking structure that is diagnostic for octahedrites".
