Compare the ways in which ironmagnesium minerals and feldspars crystallize from magma?

In Bowen's reaction series, feldspar minerals go through a continuous change of composition, while iron-magnesium groups have an abrupt change of mineral types. When magma cools, the feldspars that form are calcium-rich. As cooling continues, the feldspars react with magma and the feldspar composition changes. The result is a zoned crystal with sodium-rich outer layers and calcium-rich core. For iron-magnesium minerals, when magma starts cooling, a mineral begins to crystallize. However, when the magma temperature drops, a whole new mineral begins to form. The previously formed minerals reacts with the magma and is converted into the new mineral.


What are two feldspars found in granite?

What is the first minerals to form when magma cools that are rich in iron calcium and magnesium?

The first minerals to form when magma cools and is rich in iron, calcium, and magnesium are typically olivine, pyroxene, and/or plagioclase feldspar. These minerals have high melting points and tend to crystallize early as the magma cools.


What is the old name for the element carbon?
