Precambrian Continents

There is evidence for the early continents in cratons; scientists trace plate tectonics from early in Earth history through the formation of supercontinents, including Rodinia.

Birth of Plate Tectonics

Rodinia was the supercontinent before Pangaea. This supercontinent was probably not the first. Rocks dating from 1.1 billion years ago show how the continents were joined into this supercontinent.

15 of the largest plates mapped in the second half of the 20th century [Figure2]

  • Modern plate tectonics probably began about 3.2 billion years ago.
  • Some continents formed by 3.6 billion years ago.
  • Earlier continents came together and apart by plate tectonics processes.
  • As happens today, the plates moved due to mantle convection.
