The ocean floor spreading theory was proposed during 1961 and 62 by
Robert Dietz and Harry Hess. This concept was a revolutionary one,
and renewed the scientists thoughts on the dynamics of the ocean
bottom. Then, for example, the coincidence of the Wadati-Benioff
Zone with the subduction zone proposed by new concept was well
understood. Further development of the ocean floor spreading theory
was the proposal of new concept "plate tectonics" proposed by
Xavier LePichon and by a few others during 1967 and 68. This new
idea could solve the various conflicts involved in the "ocean floor
spreading theory." Therefore, today, scientists understand that the
plate tectonics theory was born by the ocean floor spreading
theory, which is able to cover the weak points of the latter. D/V
Glomar Challenger started her Leg Ion 20 July, 1968 from Orange,
Texas to implement the Deep Sea Drilling Project. The timing almost
coincided with the proposal period of the plate tectonics. After
carrying out a few legs of the drilling operations, the results
obtained by D I V Glomar Challenger well proved the rightness of
the newly proposed theories of the ocean floor spreading and the
plate tectonics. For us, the successful processes started by the
ocean floor spreading theory, improved by the concept of plate
tectonics and proved by the DSDP results have been a golden
monument in the field of earth sciences probably for several
centuries.
