The origin of bimodal (mafic–felsic) rock suites is a fundamental question in volcanology. Here we use major and trace elements, high-resolution Sr, Nd and Pb isotope analyses, experimental ...

The rock record and geochemical evidence indicate that continental recycling has been occurring since the early history of the Earth. The stabilization of felsic continents in place of Earth’s ...

These granite peaks are an example of felsic rock, created via plate tectonics. Credit: Basil Greber This also would mark the beginning of plate tectonics, since that process is believed to be ...
