Plate Tectonics at 50 (William Smith Meeting, October 2017) Session 1

This first session from the conference looks at the history of scientific developments leading up to the plate tectonics paradigm. After the opening welcome by Malcom Brown (President of the Geological Society) the session is chaired by Rob Butler (University of Aberdeen). Tony Watts’ (University of Oxford) introduction covers the history of tectonic concepts leading up to the 1960s and what happened next. This leads to Hank Frenkel (University of Missouri) looking at the parallel approaches taken by Jason Morgan and Dan McKenzie and the events leading up and following the Spring Meeting of AGU in 1967. Wolf Jacoby (Johannes Gutenberg University) ponders on why Alfred Wegener missed plate tectonics a century ago. Xavier Le Pichon (College de France) provides testimony from the 1960s, how he tested and then summarised plate tectonics concepts and then presents new ideas on the eastern Mediterranean. The discussion period looks at why other evidence, especially palaeomagnetism, was overlooked and then how quickly plate tectonics was adopted, taught and communicated. This set of presentations comes from a three-day meeting (3-5 October 2017) celebrating the 50th anniversary of the advent of the paradigm of plate tectonics. The meeting was convened to examine the state of the art and scope out new directions. There are 9 other sessions available to view together with the William Smith lecture by Dan McKenzie that concludes the meeting.
