From the article:
Curtin University-led research has found new evidence to suggest that the Earth's first continents were not formed by subduction in a modern-like plate tectonics environment as previously thought, and instead may have been created by an entirely different process.
Published in the journal Geology, the research team measured the iron and zinc isotopes in rock sourced from central Siberia and South Africa and determined that the composition of these rocks may have formed in a non-subduction environment.
