A new ca. 1.73 Ga mafic magmatic event in the Indian Shield: Evidence from an in-situ SIMS U-Pb baddeleyite date and geochemistry of the mafic intrusions within the Gwalior basin, Bundelkhand craton

•Reports a new in situ SIMS U-Pb baddeleyite date (1733 ± 23 Ma) in the Indian Shield.•Studied Gwalior mafic sills are derived from a melt originated from SZLM source.•Global occurrence of ca. 1.73 Ga magmatic event is limited, known from few cratons.•Depositional age of the Gwalior sediments is bracketed between 1980 and 1710 Ma.
