(Papers of the week took a small vacation while my petrology class & I tried to catch up due to a few unplanned pauses, but now we’re back!)
This week’s paper is:
Martin, V.M., Davidson, J., Morgan, D., and Jerram, D.A., 2010, Using the Sr isotope compositions of feldspars and glass to distinguish magma system components and dynamics: Geology, v. 38, p. 539-542.
(Behind a paywall–sorry.)
This paper went into the lineup due to the fact it combined chemistry (topic from week 4) with magma chamber dynamics (week 5 & 6), so its a final review on the information we just dealt with and a preview of what’s coming. I took the advice of a number of fellow instructors around the web and choose to post several questions that I wanted the students to answer & send me before our discussion this morning:
- what kind of data is being used by the authors?
- why did they choose to work with this type of data?
- identify for each interpretation the data it is specifically based on
The majority of the data is actually in a figure and not within the text, so I’m going to interested to see what the student’s reaction to that is.
