The long-favored paradigm for the development of continental crust is one of progressive growth beginning at approximately 4 billion years ago (Ga). To test this hypothesis, we measured initial 176Hf/177Hf values of 4.01- to 4.37-Ga detrital zircons from Jack Hills, Western Australia.

Along the Iceland-Reykjanes ridge traverse, 176Hf/177Hf increases southwards.

Naturally occurring Hafnium has 5 stable isotope - 176Hf, 177Hf, 178Hf, 179Hf, 180Hf.
