Evening talk by Dr. Keith James September 18th 2019. The talk was entitled, "Not Written in Stone:Plate Tectonics at 50"
Dr. Keith James is a consultant geologist and fellow of the Institute of Geophysics and Earth Sciences at Aberystywyth University in Wales. He has worked with Shell all over the world - and later with Conoco.
Dr James commenced his talk by saying that published Plate Tectonics teaching is complacent. It should adapt to emerging data, including multiple working hypotheses, and enable students to think.
He then went on to describe a number of dicoveries that he suggests should put the theory of plate tectonics into doubt.
His ideas are controversial and many will disagree so the following link is to a PDf of his ideas and you can come to your own conclusions.
