Tom, Last spring you posted to the ISOGEOCHEM list the following query: >Dear All: >Those of you who are teaching isotope geochemistry (stable AND radiogenic): >What are you using for a text? I'm ust curious as to what kinds of responses you got -- I saw the responses on the ISOGEOCHEM list suggesting books dealing with various aspects of stable isotope geochemistry, but did you turn up any good alternative to Faure's Principles of Isotope Geology for a more general treatment? Thanks, Tim -- -- Timothy Thorpe Allen, Ph.D. <[log in to unmask]> -- -- Geology and Environmental Studies, Keene State College -- -- http://kilburn.keene.edu/ --
