The observation is made that there are very strong similarities between the supercontinents Columbia,Rodinia and Pang(ae)a.If plate tectonics was operating over the past 2.5 billion years of Earth history,and dominated by extroversion and introversion of ocean basins,it would be unusual for three supercontinents to resemble one another so closely.The term strange attractor is applied to landmasses that form a coherent geometry in all three supercontinents.Baltica,Laurentia and Siberia form a group of strange attractors as do the elements of East Gondwana (India,Australia,Antarctica,Madagascar).
