"Tiny crystals found in an Australian rock formation may be the key to understanding what earth looked like in its very earliest days, researchers say; a new study of 4-billion-year-old crystals seems to indicate that our planet already had plate tectonics, and may have looked much like it does today.
Little is known about the so-called Hadean or the ‘hell-like’ period of Earth’s history, which spans the time from Earth’s formation 4.6 billion years ago until about 3.8 billion years ago. The best geological clues of this era come from hard minerals called zircons, which have survived weathering and can be found within younger rocks."
