I might be sticking my neck out a bit by attaching this article, but I'm sure that plenty of gazers will find it of interest. Please note the copyright by the Geological Society of America. Downloaded online as a PDF because I am a member of the GSA, published in the June 2007 issue of "Geology." Even though it is short, tthe article occupies 934KB due to graphics.
