Hot, wide, continental back-arcs explain Earth’s enigmatic mid-Proterozoic magmatic and metamorphic record
Higher than average thermobaric ratios (temperature/pressure) of metamorphic rocks and abundant ‘dry’ ferroan magmatism including massif anorthosite suites are two enigmatic features of the mid-Proterozoic (1.85–0.85 Ga) that have unclear origins. It has been proposed that elevated mantle temperatur...
