This is a simple essay explaining the Bowen Reaction Series.

This work made it possible to restart a complex hardening of geochemical relationships, called Bowens Reaction Series. This series shows that silicate mineralscancrystallize from mafic magmas in two ways, in a non continual series or a uninterrupted series. Iron and magnesium mysterious silicates(ferromagnesian) crystallize one after some other in a proper(postnominal) sequence (Chernicoff 56). Because each successive indication of this mineral crystalise differs from the one that came before it, this progression is called the discontinuous series. In the discontinuous series the first ferromagnesian mineral to crystallize is olivine. Olivine has a small(a) silica content and a relatively simple coordinate of self-sustaining tetrahedra (Chernicoff 56). At the same temperatures as the olivine and the pyroxenes crystallize, so does the calcium feldspar. As these crystals continue to interact with the remain liquid, sodiumions from the liquid magma replace the calcium ions in the calcium feldspar (Chernicoff 57). ultimately the crystals are completely reborn to sodium feldspar. Because one type of ion is cosmos replaced by a similar ion; the inner(a) structure does not change. This progression is called the continuous series (Chernicoff 57).

After both minerals from the discontinuous series and the continuous series have crystallized completely from an ab initio mafic magma, slight than 10% of the original liquid remains (Chernicoff 57). Depending on its composition, this liquid whitethorn this instant contain higher concentrations of silica, chiliad, and aluminum. In such a case, potassium feldspar, potassium-aluminum mica, and quartz are the move minerals to crystallize (Cherincoff 57).
