| Description | Brief file entitled 'Triple junctions', relating to the paper: McKenzie, D & W J Morgan, "The evolution of triple junctions", 'Nature', vol 224 (1969), pp125-133.
Comprises: letter from Fred Vine, assistant professor of geology and geophysics at Princeton University, New Jersey, USA, recounting the struggles he has had trying to get Jason Morgan, McKenzie's co-author, to finish his side of the paper, giving detailed comments on the draft paper, and finishing with Vine stating that he has changed his mind about applying for the vacant lectureship at the University of Edinburgh, 27 February 1969*; brief notes and equations; copies of various figures from previously published papers which have been annotated, notably by Tanya Atwater* indicating the magnetic anomalies around the San Andreas Fault, some of which appear in the final published paper; short typescript paper "Gulf of California, San Andreas Fault, and East Pacific Rise" by Mason L Hill, 1968*, which concludes by stating that until more studies are undertaken the 'new global tectonics', as put forward by Jason Morgan, can only be treated as a working hypothesis. |
