Igneous Petrology Series: Lesson 9 - Ternary Peritectic Phase Diagrams

Welcome to the Igneous Petrology Series.

The igneous petrology series is a series of short and simple educational videos on topics such as thermodynamics, geochemistry, and geology.

In the fundamentals playlist, I talk about thermodynamics, element classification, and phase diagrams. These can be quite complicated subjects, but once they're broken down, you'll see they are not quite as daunting as first thought!

I think this is the best explanation of ternary peritectic....Good work really appreciate

Great video! I have a question about the green point which dodges the peritectic point at 5:03. Does that mean in the end when the entire liquid is cooled that there is a mineral assamblegde of forsterite (Olivin), enstatite, anorthite and cristobalite? Because by doging/bypassing the peritectic point the olivin does not get the chance to break down by reacting with the melt and form more enstatie?

How do you project your own experimental liquids on this projections? Any useful softwares?

Let's add a point here. The An-En join will not intersect the peritectic reaction curve. If intersect it will not a peritectic curve rather we can call it as a cotectic curve like other cotectic curves.

merci pour cette vidéo c'est une vraie mine d'or (un peu comme celles dans le Yukon chez vous les américains(piou piou))

Thanks for really helpful videos.
I have a question! Do the track of ternary diagrams have any differences between equilibrium and fractional crystallization?

Plzz make vid for diopside forsterite silica ternary system. plzzz

[farihatasnim]

Why do we draw a line from the enstatite end member tbrough the system? Why do it dodging the peritectic point?
