SEMINAR ON MAGMAS: SOURCE TO SURFACE
Instructors: Kiser, Dasgupta, Gonnermann, Lee, Levander, Morgan, Niu, Lenardic
MONDAY: 12-1 PM, RM 327
We will conclude the seminar with a discussion on the effect of local stresses on volcanic eruptions (Gudmundsson, 2006).
The MASH zone will be discussed this week (Hildreth and Moorbath, 1988).
11/02/15 & 11/09/15
This week we will discuss a review paper on magma reservoir differentiation (Jaupart and Tait, 1995).
Kerr et al., 1989
Worster et al., 1990
The formation of large silicic magma reservoirs will be discussed this week (Jellinek and DePaolo, 2003).
Transitioning to subduction zones, we will discuss a paper on melt formation in the mantle wedge (England and Katz, 2010).
This week we will discuss melt conduits in the mantle section of the Oman ophiolite (Braun and Kelemen, 2002).
Expanding on our discussion of mid-ocean ridges, we will discuss a paper on the Oman ophiolite (Kelemen et al., 1997).
This week we will transition to the magmatic systems associated with mid-ocean ridges. Two papers on seismic surveys over the East Pacific Rise and Juan de Fuca Ridge will be discussed (Kent et al., 2000; Carbotte et al., 2012).
This week our discussion will be motivated by two short, nontechnical papers published in Elements in 2008 (Miller and Wark, 2008; Bachmann and Bergantz, 2008).
This week we will discuss a 2015 seismic study published in Science by Huang et al. which images new details of the magmatic system beneath Yellowstone. As suggested by Helge, the 2009 review paper by Smith et al. is a good starting point if you want more background on previous work at Yellowstone.
Here you can download the powerpoint presentation of the Huang et al., 2015 paper.
Below there are three papers on the crustal structure of the Snake River Plain. The first two papers are results from a rather old refraction experiment along and across the SRP. The third is a more modern study using receiver functions from an array across the SRP. Just look at the figures of the crustal models.
