| Iron meteorite | The meteorite is composed of about 84% iron and 16% nickel, with traces of cobalt. It is classified as a nickel-rich ataxite. A crust of iron hydroxides is locally present on the surface, owing to weathering. |
Iron meteorite consist overwhelmingly of nickel-iron alloy. The metal taken from these meteorites is known as meteoric iron and was one of the earliest sources of usable iron available to man.
While they are fairly rare compared to the stony...

|
Chondrites are stony meteorite that have not been modified due to melting or differentiation of the parent body. They formed when various types of dust and small grains that were present in the early solar system accreted to form primitive asteroid....

| Achondrite |
|
An achondrite is a stony meteorite that consists of material similar to terrestrial basalt or plutonic rocks. Compared to the chondrite, they have all been differentiated and reprocessed to a lesser or greater degree due to melting and...

| Pallasite |
|
A pallasite is a type of stony-iron meteorite. It consists of cm-sized olivine crystals of peridot quality in an iron-nickel matrix. Coarser metal areas develop Widmanstätten pattern upon etching. Minor constituents are schreibersite, troilite and...

| Mesosiderite |
|
Mesosiderites are a class of stony-iron meteorites consisting of about equal parts of metallic nickeliron and silicate. They are breccias with an irregular texture, silicates and metal occur often in lumps or pebbles, as well as in fine-grained...
