Meteorites are solid bodies that come from space and fall to the surface of the Earth. Their dimensions vary, and they can be large masses weighing several tons or small fragments, even being vaporized when they explode when they hit the Earth. The cavity or depression that the meteorite produces when it hits the Earth is known as an impact crater.
Meteorites are classified according to their mineralogical composition into the following types:
– AEROLITES (stony): They have a composition similar to rocks. Silicates predominate. They can present chondrules (CHONDRITES) or not (ACHONDRITES).
– MESOSIDERITES (stony-iron): They are composed of similar amounts of silicates and Iron-Nickel alloys.
– SIDERITES (iron): Predominantly present Iron-Nickel alloys.
