A basic understanding of the various tectonic hypotheses is necessary
to understand Earth geodynamics. Tectonics is the key to unlocking the
regional structural geometry, and the regional geology is the key to
unlocking the geodynamic history. Much of this history is recorded on
the oceanic lithosphere. Lithosphere motions determine regional structure
and the geomorphology. Lithosphere motion after the principal production
phase gives rise to additional stresses which may or may not change
the geomorphology of an existing feature. Thus secondary and tertiary
tectonics create secondary and tertiary features on the primary structure.
The basic assumption is that three physical possibilities exist; Earth
can maintain the status quo, expand, or contract. Using ocean floor
rock ages to show the fallacy of the magnetic isochrons, expansion and
status quo are refuted. Contraction driven by the surge-tectonic hypothesis
seems to be the explanation for ocean floor lineaments recorded by bathymetry
and structure.
Keywords: plate tectonics, earth expansion, magnetics, surge tectonics
