First SHRIMP U-Pb and 40Ar/39Ar chronological results from impact melt breccia from the Paleoproterozoic Dhala impact structure, India

The ~11-km-wide Dhala impact structure, in north-central India, is located in Archean granitoids of the Bundelkhand craton and is partially exposed beneath Paleoproterozoic sediments belonging to the Vindhyan Supergroup, which place the age of the structure between ca. 2.5 Ga and ca. 1.7 Ga.
