3. Use data from Appendices A and F to compute a modern value of the sulfate residence
time in the ocean. Draw a sulfur cycle involving erosion, rivers, the ocean, ridges, and
the burial of sedimentary pyrite. Examine
Fig 9.8
and propose possible interpretations
to the fast
34
S oscillations in the Cretaceous and the Paleocene.
