Examples
As the meteorite cools and taenite and kamacite are sorting out of each other some of the trace elements will prefer to be located in taenite or kamacite.
All ordinary chondrites contain kamacite in decreasing abundance as you move from H to LL chondrites. citation Kamacite is also found in many of the less common meteorites mesosiderites and E chondrites.
For kamacite, the alloy is usually in the proportion of 90:10 to 95:5, although impurities (such as cobalt or carbon ) may be present, while for taenite the nickel content is between 20% and 65%.
Due to the face centered nature of the kamacite lattice and the body centered nature of the nickel lattice the two make intricate angles when they come in contact with each other.
However many museums and universities have samples of kamacite in their collection.
Kamacite is also only stable at low pressures as can be assumed as it only forms in space. citation Effect of shock Metallographic and X-ray diffraction can be used on kamacite to determine the shock history of a meteorite.
