Magmatic thickening of crust in non–plate tectonic settings initiated the subaerial rise of Earth's first continents 3.3 to 3.2 billion years ago
When and how Earth's earliest continents—the cratons—first emerged above the oceans (ie,
emersion) remain uncertain. Here, we analyze a craton-wide record of Paleo-to …
