Meteorite hunters have created a funny term to refer to all the many rocks that look similar to meteorites but are not, they call them meteor "wrongs". Pinterest. However, the commonest type of meteorite,the chondrites (which are a stony material), do not appear to have a parent body in the asteroid belt (maybe this type of material is specific to Earth-approaching asteroids?)

It is therefore unlikely that a meteorite would be found in or near the ocean or a riverbed, although meteorites have occasionally been found in dry washes in the desert. They are comprised of roughly equal amounts of nickel-iron and stone and are divided into two groups: pallasites and mesosiderites. Barringer Crater in Arizona. The more common meteorite types are chemically and geologically primitive, and while their chemistry may offer a fascinating glimpse into the planet-forming . Stony meteorites, the most common type of meteorite, are generally composed of approximately 75 - 90% silicon-based minerals, 10 - 25% nickel-iron alloy, and trace amounts of iron sulfide. The biggest meteorite ever found on Earth is the Hoba meteorite. Pallasites are "believed to form between the outer shell and core of an asteroid" (8), and the primary silicate mineral found in them is olivine. Only one other LL7 fall has ever been recovered."
