A mantle-plume trigger for one of Earth’s largest Precambrian silicic large igneous provinces in the Amazonian Craton

The Amazonian Craton is host to one of Earth’s largest Proterozoic silicic large igneous provinces (SLIPs), the Orocaima SLIP (ca. 1.98 Ga). Nevertheless, the mechanism(s) responsible for this large-flux felsic magmatic event and its relationships with ...
