Title: Pump-Like Tidal Driving of Tectonic Plates: GEOLOGIC NOTES

Author(s): George W. Moore (2)


Large oppositely directed torques at the leading and trailing edges of solid-earth tidal bulges alternately may open and close the lithosphere at lines of sea-floor spreading. Subcrustal material then could rise during the opening stage and remain as new crust during the closing. This mechanism accounts particularly well for the movement of small plate fragments, and it may help to explain the coherence of very long slender plates such as the American.
