Reading assignment Van der Hilst (31/03/1998)

Following are three short papers for the presentations. In addition to this, all should read the review paper by Thorne Lay:
Lay, T., The fate of descending slabs, Annu. Rev. Earth Planet. Sci. , 22, 33-61, 1994.

NB. With the exception of the Wick & Richards paper, copies of all paper are in the file holder at my door (Rm 54-514). If you take these to make xeroxes, PLEASE RETURN THEM so that others can use them too!
