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.

Magma Reservoir Longevity: Zircon age ranges demonstrate that mafic magma reservoirs can persist for up to ~10⁷ years.
Crustal Evolution: Highlights the role of mantle-derived mafic magmas in sustaining magma systems and shaping island arc crustal evolution.
