Description

Chemical Composition: Fe,Cr,Mg Crystal System: Anhedral Description: Common Name: Ferrochromanganese (Meteorwrong) Chemistry: Fe,Cr,Mg Group: Ferrochromanganese Location: Unknown Description: Original identification: "Heavy, irregularly shaped with semi-metallic look. Dull bronze to rusty brown. Widdmanstatten patterns are apparent." In Feb 2012, this specimen was identified by Dick Pugh, PhD, of the Portland Meteor Lab as being Ferrochromanganese - one of the most commonly misidentified 'meteorites' in Oregon. It is an artificial alloy made in the making of steel. PHYSICAL CHARACTERISTICS: A meteorite is a natural object originating in outer space that survives impact with the Earth's surface. Meteorites can be big or small. Most meteorites derive from small astronomical objects called meteoroids, but they are also sometimes produced by impacts of asteroids. When it enters the atmosphere, impact pressure causes the body to heat up and emit light, thus forming a fireball, also known as a meteor or shooting/falling star. The term bolide refers to either an extraterrestrial body that collides with the Earth, or to an exceptionally bright, fireball-like meteor regardless of whether it ultimately impacts the surface. Type of Fossils Present: None Hardness: 9 Corundum Luster: Metallic Occurrence: Ferrochromanganese is an artificial alloy made in the making of steel. Pressure: High Rock Color: Dark Rock Origin: Terrestrial Rock Type: Metamorphic Surface Process: Not apparent Texture: Mircocrystalline Variety: Other terms: pseudometeorite, if it actually resembles a meteorite, and leaverite. The latter is derived from "Don't bother picking it up, just leave it right there."
