What is typically used to refer to meteorites that contain predominantly iron and nickel?

Siderites are the term specifically used to describe meteorites that contain a significant amount of iron and nickel. These meteorites are primarily composed of metallic iron and can often be identified by their high density and metallic luster. The composition of siderites is of great interest in both planetary geology and materials science, as they can provide insights into the conditions and processes that formed them in space.

In contrast, lunarites are meteorites originating from the Moon, aerolites refer more generally to stony meteorites that may contain silicate minerals, while tektites are glassy objects formed from the debris of meteorite impacts on Earth. Understanding the specific characteristics and classifications of meteorites helps in studying their origins and the history of our solar system.
