Measurements of areas of sea floor broken up into age groups show that apparent areal global sea-floor spreading rates increase exponentially from Jurassic to Holocene time, proving that subduction has taken place in that time. The sea-floor spreading phenomenon is a coordinated global process where, at a given time, high spreading rates in one ocean basin are compensated for by low rates in another. Sea-floor spreading is symmetric within 15% over periods of 60 to 165 m.y. This study shows… CONTINUE READING
