Bowen's Reaction Series

Front

What is Bowen's Reaction Series?

Back

A sequence that illustrates the order in which minerals crystallize from cooling magma, showing the relationship between temperature and mineral composition.

Front

What type of minerals crystallize at higher temperatures?

Back

Minerals that are typically low in silicon and high in iron and magnesium.

Back

Minerals that are typically high in silicon and low in iron.

Front

Where would plagioclase be found in Bowen's Reaction Series?

Back

At the top of the continuous series.

Front

What elements are abundant in minerals that crystallize at high temperatures?

Back

Iron and magnesium.

Front

What is the significance of the discontinuous series in Bowen's Reaction Series?

Back

It shows the crystallization of minerals that change composition as temperature decreases.

Front

What is the significance of the continuous series in Bowen's Reaction Series?

Back

It illustrates the gradual change in composition of plagioclase minerals as temperature decreases.

Front

Which mineral melts first as rock heats up?

Back

Potassium Feldspar.

Front

What is the relationship between temperature and mineral composition in Bowen's Reaction Series?

Back

As temperature decreases, minerals with higher silica content crystallize.

Front

What is a common characteristic of minerals that crystallize at high temperatures?

Back

They tend to be dark-colored and dense.
