Subject: Crustal Shift Theory
I was initially interested in Crustal Shift mechanism as a way to explain paleo-environment changes in the Geologic Record, and existence of ancient maps of the Antarctic coastline. I thought that Hot Spots would be a good way to identify changes in position of continents. This is because they all have very distinctive chemical compositions and are relative static in relation to the crust. However I soon realised that they in fact disprove crustal slip theory, this is because the Hawaiian islands for example show a continuous movement over a hot spot during the last 30 Million years. See http://www.oceansonline.com/hotspots.htm There are other mechanisms as noted on your site, such as the effects of Mechanics of Centrifugal forces that when combined with the movement of plates and meteor impacts may I believe provide a better explanation.
( For the record I have a degree in Geology/Geophysics )
