Abstract
Detrital monazite geochronology and geochemistry provide crucial constraints on the crustal evolution and metamorphic history of continental landmasses. In this study, we investigate detrital monazites to reconstruct the tectonic and magmatic evolution of the North and South American continents during the ‘Boring Billion’ period (1.8–0.8 Ga).

Key Highlights

  • Crustal Evolution: Reconstructs the tectonic and magmatic history of North and South America during the middle Proterozoic (“Boring Billion”) using detrital monazite proxy.
  • Multi-proxy Approach: Combines U–Pb geochronology and trace element geochemistry of detrital monazites to trace metamorphic and igneous thermal events.
