I am in a Geology 100 class and for the longest time I was confused by Bowen's Reaction Series. This video really helped me out, just wanted to say thanks! Great video!
Just to clarify a couple of thing, Does olivine is form up until a certain temperature and then stop forming when pyroxene starts to form? Secondly, in both the discontinuous and continuous reaction series, when a mineral phase has formed with cooling - provided that temperature doesn't increase again - does that mineral phase remain? I.e. if olivine crystals were formed and then the composition of the melt was less Mg and Fe-rich, do the olivine crystals react with the melt and change to a different composition or are the olivine crystals always removed from the melt and no longer interact with it i.e. fractional crystallisation? I'm getting confused over this as I don't really understand my teacher's definition of discontinuous reaction: "As magma cools and its composition changes, mineral phases react with residual magma and change to a different mineral phase - providing that there is sufficient time for the reactions to occur"? Thanks
Great question! If you look at the quartz, you can see that it filled in the spaces between the other mineral crystals that had already formed at slightly higher temps.
+Caroline Sheffield Because the olivine doesn't change into pyroxene; The cooler magma will crystallize into new minerals, without affecting the minerals that has been already created.

I keep coming back to Bowen’s. Your explanations are the clearest.

Thank you for clearing up this topic! I have been avoiding it but have an exam coming up. It all makes sense now.
Awesome way of explaining, it was very helpful, Thank you very much!
Fun fact about muscovite. It was named after Muscovy in Russia where it was found and used to make small windows it used to be called Muscovy glass
Thanks for this video! And keeping it up.
I am arabic and learning a lot thx , I am so glad
Very nice...down-to-earth explanation. Thank you.
thank you somuch for your quick response...looking foward to more videos that would make earth science intresting
Thank you, its been very helpful ...

that was amazing!!!
what is the name of the text book that you are using
very good
thanks
Thanks 👍👍
the guy seems so high
still don’t understand the continuous vs discontinuous series
We learn that in high school 😭
So, how do we get amphiboles, potassium feldspar and quartz in one rock?
Great question! If you look at the quartz, you can see that it filled in the spaces between the other mineral crystals that had already formed at slightly higher temps.
If the olivine changes into pyroxine as it cools, how can you hold a chunk of cool olivine in your hand? What major piece am I missing here?
+Caroline Sheffield Because the olivine doesn't change into pyroxene; The cooler magma will crystallize into new minerals, without affecting the minerals that has been already created.
Differentiation. The formation of pyroxene is contingent on the availability of elements in the melt.
Good question.
