Some iron meteorites contain oxygen-bearing phases: chromite, phosphates, and silicates, which can be isotopically analyzed to search for genetic associations with stony meteorite groups. There is a clear isotopic and chemical connection between the group IAB irons and winonaites (one class of primitive achondrite, discussed below). Iron was available to some of the world’s oldest civilizations as early as 1500 B.C., although some accounts place its discovery as far back as 2500 B.C. It is called a “Metal of Antiquity” and was first obtained from meteorites that had fa...

It is like the glaze on ceramic ware. Usually, fusion crust is black because of iron in the meteorite. But sometimes it is brown or greenish or even clear.

Specimens are weathered, but still adhere strongly to a good magnet.2) Is the specimen rust-like, brown, or orange colored? Weathered meteorites (found buried or in soil) will tend to be dark and rusty looking. Man-made iron slag has similar colors. Naturally-occurring iron compounds in Kentucky can also be dark and rusty, but sometimes have a purplish color or hue. Iron-nickel metal. More than 95% of all meteorites contain iron-nickel (FeNi) metal. As a consequence, meteorites have concentrations of nickel that are much greater than that of nearly any terrestrial rock. “Iron-nickel” means that the metal is mostly iron but it also contains 5-30% nickel.Weathering and Erosion - When the land is worn down by the elements, it's called weathering.
