Dear All: Those of you who are teaching isotope geochemistry (stable AND radiogenic): What are you using for a text? I think Faure's book is still great but it's quite out of date now. More recent books don't seem to work either. Has anyone found that one of these works well for them? Are there any new books out there? I suspect most of you put together your own readers, but I just wanted to check. -Tom Johnson *********************** Prof. Thomas M.
