Reading assignments Stan Hart (03/03/1998)
The following papers will be discussed on Tuesday, March 17
- Hoffman, A., Mantle geochemistry: the message from oceanic
volcanism, Nature, 385, p. 219-229, 1997.
- Carlson, R.W. Mechanisms of Earth differentiation: consequences
for the chemical structure of the mantle, Reviews of Geophysics,
32, p. 337-362, 1994.
(Concentrate on the first section of the paper, pp338-345, titled
"Differentiation accompanying planet formation", with the main questions to
be asked being Are the upper and lower mantles the same chemical
composition or not? and Why is this issue important for the discussion of the
scale of mantle convection?.)
- Javoy, M., The integral enstatite chondrite model of the Earth Geophys. Res. Lett., 22, 2219-2222, 1995.
N.B. There is no class on Tuesday March 10th: instead of
class, study carefully the Davies & Richards '92 (see last
week's assignment) and the Carlson '94 and Hoffman '97
(see below) papers.
These are good overviews and we'll come back to them several
times during this course.
Other useful review articles that I can recommend are:
- Silver, Carlson, and Olson, Deep slabs, geochemical
heterogeneity, and the large scale structure of mantle
convection: investigation of an enduring paradox, Rev.
Earth Planet. Sci. 16, 477-541, 1988.
- Montagner Can
tomography tell us anything about convection in the mantle?
Rev. Geophys., 32, 115-138, 1994.
