Meteorites are often divided into three overall categories based on whether they are dominantly composed of rocky material (stony meteorites), metallic material (iron meteorites), or mixtures (stony–iron meteorites).

What type of meteorite is the most abundant?
Stony meteorites are by far the most common. More than 95% of meteorites observed to fall to Earth are stony. They can be divided into chondrites and achondrites.

What are the different types of meteorites found on Earth?
There are three major types of meteorites: the “irons,” the “stonys,” and the stony-irons. Although the majority of meteorites that fall to Earth are stony, most of the meteorites discovered long after they fall are irons. Irons are heavier and easier to distinguish from Earth rocks than stony meteorites.
What are the different types of stony iron meteorites?
There are two different types of stony-iron meteorites: pallasite and mesosiderite. Pallasites contain big, beautiful olive-green crystals – a form of magnesium-iron silicate called olivine – embedded entirely in metal.
Are there any meteorites that do not contain chondrules?
It was a witnessed fall (1960) and is a rare type of achondrite—a stone meteorite which does not contain chondrules. Eucrites are volcanic rocks from other bodies in the solar system, and Millbillillie is one of the very few meteorites which does not contain iron-nickel.
How are meteorites used to study the asteroid belt?
They can use photographic observations of meteorite falls to calculate orbits and project their paths back to the asteroid belt. They can also compare compositional properties of meteorites to the different classes of asteroids. And they can study how old the meteorites are – up to 4.6 billion years.
