Nature of magmatism and sedimentation at a Columbia active margin: Insights from combined U-Pb and Lu-Hf isotope data of detrital zircons from NW India

► Distinctive age peak of ca. 1.85 Ga in detrital zircons of north Indian metasediments. ► An active geodynamic realm along the entire margin of north India at ca. 1.85 Ga. ► A coherent crustal entity of north India-Madagascar-eastern Cathaysia-South Korea during Columbia times.
