meteorites

Meteorites, classified according to chemical and petrographic characteristics, chemical composition according to the

* Stones removed (aerolite)
* Ferri (siderite) and
* Acalculous ferrous (fossil-Dee) (Siderolit)

are classified into three groups. Wedding meteorites, iron, silicon, carbon, magnesium, aluminum and oxygen occurs. Moored in the meteorite nickel, gallium, germanium and iridium are found. Wedding ferrous olivine in meteorites that contain various metals.

When large meteorites falling to earth or a large crater and disconnected parts may constitute a small craters. Meteorite crater formation, but the density, velocity, angle of entry into the atmosphere and strikes based on characteristics of the material that does not always create a crater structure.
