How to Determine the Elemental Composition of Minerals

Pure Minerals always Have same Composition A pure mineral, one that is not mixed with any other mineral, is always of the same composition (certain exceptions). For example, iron pyrites is composed of iron and sulphur, in the proportion of 46.67% of iron and 53.33% of sulphur; and any specimen of the pure mineral will, when analyzed, always contain iron and sulphur in these proportions.

What Is the Composition of Cast Iron? | Reference.com

When the ore is melted, it is poured into molds. It cools and forms a scale on the surface that acts as a protective covering for the metal. However, cast iron is naturally prone to rusting because of its high iron composition. When iron comes into contact with oxygen and water vapor, a chemical reaction occurs, and rust is the visible result.

Composition of Mars - Wikipedia

The elemental composition of Mars is different from Earth's in several significant ways. First, Martian meteorite analysis suggests that the planet's mantle is about twice as rich in iron as the Earth's mantle. The planet's distinctive red color is due to iron oxides on its surface. Second, its core is richer in sulphur.
