U-Pb age data from southwest Madagascar provide a compelling case that the pre-Gondwana Indian plate was stitched with the arc terranes of the Arabian Nubian Shield along a suture that closed between 580. Ma and 520. Ma. The key observations supportive of this interpretation are: (1) metamorphism da...
