SEPM Strata:  We do not have time to keep up with the latest innovations in everything, so we need to find groups of dedicated individuals who are keen to keep abreast of the changes, and more importantly, tell us!  SEPM Strata is a site that does exactly that for sedimentology and sequence stratigraphy.  The are lots of explanatioons, examples, animations and videos.  A great sedimentology refernce resource.

Tell your friends!
