Greetings Doug Ok lets look at global motion in relation to Antarctica >>From the viewpoint of Antarctica, I expect it is a case of ridges moving themselves away from Antarctica, primarily toward Australia, and minimally if at all toward Africa.<< If we assume that the Mid Point of the Ridge is moving away from Antarctica then why are the shift faults extending inward? The plate is forming as the opposite plate pulls away why wouldn't the Antarctic plate fill in the shift faults as a solid without the fault? >> I will go on a buying spree on my return to Calif., and high on the list is a globe (right after my nervous breakdown; see my message to Lanny), very preferably one with seafloor relief. (Anyone know a good place to look?) << Mine is the National Geographic Physical Globe approximately 18". Shows all the basin features but is from 1974. I'll been meaning to get a new one. There is a flat map in one of the recent issues that is pretty good. >>I am still trying to figure what you mean by "bowing". Is it the angling of the transform faults relative to the spreading ridges, or what?<< Bowing is when the shift fault or transform fault has an arc to it. This would be shifting along the ridge in both theories. All curved features would be indicating this shift. Based on how you have explained Mid Ridge formation then how do we explain this… the Ridge between Antarctica and Africa appears to have shifted 6500 miles lateraly along a 850 mile section of ridge. If the various maps portray that area correctly. How do you explain this much shifting here and where was this motion distributed worldwide? Kamron Kamron
