The world's oldest rocks are spread across the globe and paint a picture of Earth's turbulent early history. Here are some of the most notable and important formations scientists have discovered.
This volcanic history is decisive for determining the age of the crustal rock. Since their formation, lunar rocks (like terrestrial rocks) contain radioactive isotopes. Isotopes are variations of ...
and the consequent implications for crustal structure and tectonic evolution of continents. Much of my research involves the integration of tools from structural geology, petrology of all rock types, ...
Resetting the geological clock This volcanic history is decisive for determining the age of the crustal rock. Since their formation, lunar rocks (like terrestrial rocks) contain radioactive isotopes.
"Not only could thick crust in the southern highlands have generated ... "Granites aren't just rocks; they're geological archives that tell us about a planet's thermal and chemical evolution ...
