UCLA Meteorite Gallery Is Out Of This World
Within their collections, many a rockhound has at least one sample of a space rock, better known as a meteorite. Meteorites are truly rare. One meteorite researcher has been contacted by 2,100 people who claimed to have discovered one. Of the 2,100, only seven had found a true meteorite. The rest of the specimens mailed in were hematite or magnetite (iron ores), heavy minerals such as galena, slag from smelting, or just common rocks.
