We’ve just finished igneous rocks in lecture & lab, but haven’t gotten far enough into metamorphic rocks to really appreciate a paper yet, so this week we’re reading:
Dufek, Josef and Bachmann, Olivier, 2010, Quantum magmatism: Magmatic compositional gaps generated by melt-crystal dynamics: Geology, v. 38, p. 687-690.
(sorry about the paywall…)
The questions I proposed came from where last week’s discussion went (mainly about why the diagrams were important to the paper & what they were trying to convey):
- what is their data comprised of?
- how do their interpretations relate back to the data?
- are all of the diagrams in the paper needed?
- would you want another diagram or two?
I was tempted to talk about the England & Katz Nature paper, but I thought that the thermal modeling might be a bit too much for the students. Maybe when we get to subduction zones in the tectonic portion of the class…
