Scientific paper
A defense is conducted of the proposition that continental crust is recycled into the mantle and that the earth is in a near-steady state, with essentially constant volumes of ocean and crust through geological time. A contrasting view, that the continental crust has grown with time, has been repeatedly expressed by Moorbath (1977, 1978). It is pointed out that his arguments against recycling are not persuasive, and that the evidence which he presents is easily accommodated in a no-continental-growth model. Attention is given to evidence of continent and ocean volume, early planetary differentiation, continental accretion and destruction, evidence for the subduction of sediment, a quantitative simulation of the no-growth hypothesis, the Pb isotope evolution, the apparent single-stage evolution of Pb and Sr isotopes in ancient rocks, the inert gases He-3 and Ar-36, stable isotopes in sediments and ocean water, and steady-state chemical sedimentology.
