½éÉÜ£º The book by Gary Nichols, a completely revised edition of his earlier work, is such a book. It is well written, clearly illustrated, and it covers (almost) all topics that are important in the two earth-science disciplines mentioned in its title. (Journal Of Sedimentary Research, June 2009) I think that Nicols' book is most valuable, not only for students and teachers, but also for graduates and professionals who become involved in a sedimentological topic outside their own narrow specialism.
