Abstract

Geologic records of isotopic changes in ocean composition present the possibility of unraveling the history of secular changes in the geochemical cycles of carbon, sulfur, and strontium. In general, the conventional interpretation of the C and S isotopic age curves, as reflecting changes in burial fluxes, is favored; however, short-term fluctuations may have been caused by these other effects. For Sr there is no clear, conventional interpretation of secular variability in oceanic isotopic composition against which to weigh the alternatives. -from Author
