Onset of plate tectonics by the Eoarchean
One of the most contentious areas of Earth Science today is when, or whether or not modern-
style plate tectonics was in operation in the Archean Eon. In this review we present evidence …

Formation and evolution of Archean continental crust: A thermodynamic–geochemical perspective of granitoids from the Tarim Craton, NW China
When and how continental crust formed and evolved to its current state is a fundamental
question regarding crust–mantle evolution and geodynamic regimes on the early Earth …

Is plate tectonics a post-Archean phenomenon? A petrological perspective
The petrogenesis of contemporary igneous and metamorphic rocks is commonly explained
by plate tectonics, but how far back in time does this relationship hold? Here we investigate …

Time-space evolution of an ancient continent, a window to changing crustal architecture: Insights from granitoids of Singhbhum Craton, eastern India
Archean cratons display spatial and temporal changes in the composition and thickness of
the crust, which has important implications for intracrustal differentiation, attainment of long …

Strongly peraluminous granites across the Archean–Proterozoic transition
CE Bucholz, CJ Spencer - Journal of Petrology, 2019 - academic.oup.com
Strongly peraluminous granites (SPGs) form through the partial melting of metasedimentary
rocks and therefore represent archives of the influence of assimilation of sedimentary rocks …
